Starting a new thread for this setup to document the widest rear wheel/tire combo for the coupe. Hoping it helps others who are interested in doing the same.

I ordered the wheels April 13th and they were just shipped. Forgestar CF10 finished in textured black in 20"x12" +45 rear and 20"x9" +35 front. Should have them sometime this coming week. I can't say enough about how helpful Paul at Howey Industries has been in assisting me in the perfect aggressive fitment of this setup.

Just ordered the Nitto Invo's from my local Discount Tire who graciously price matched OnlineTires' price. Tire sizes 345-25-20 rear and 275-30-20 front. Scheduled for mounting Monday, May 21st.

The TPMS are all black GM/Vette sensors from ebay. The seller guaranteed them to work on the V.

These wheels are going on an evo green coupe lowered on Eibach springs. Black Forgestar lugnuts will be securing them. Eventually all chrome will be plasti-dipped matte black.

Check back May 21st for pics.

When do you expect delivery of your car? Wheels? Cant fn wait to see how this works out.. I know it isnt directly applicable to us sedan guys,, but gives motivation either way.. If you get the wheels and tires before your car comes in,, we should throw them on the back of my sedan and see how close this setup is for working with sedans.. maybe an 11" width with a minor offset adjustment would work?? hmmm Traction envy is strong right now!!

Wheels came in yesterday. Tires will be here Monday. Should have the car to put them on soon! haha

There is zero chance of these fitting on the sedan. The offset makes them stick out about 43mm further than the stock sedan wheels.

About the widest you can do on the sedan is a 10.5 or 10.75 rear wheel with a 305 or 315 tire. People have put the 11" rear wheel and 325 on the back of the sedan, but it just doesn't look right to me and there are some minor clearance mods to perform.

Wheels are in and tired are mounted, but one wheel has finish issues on the face that should have never passed QC. Slightly annoyed right now... waiting for word from Forgestar on how to resolve. I'll. Tell you this much, I'm not sensing it back and waiting another 5 weeks for a replacement.

Snap some pics of the fitment down the front and down the rear. Want to see if its in, flush, poke, etc.

btw welcome to the rim game, there is always drama at this level. Scratches, tire shops damaging them, stupid detailers using wrong chemicals or letting it dry in the sun wrecking finish. Past 2 yrs I've had a set of work wheels (12 weeks), and 2 sets of HRE. Everytime someone else touches them without supervision something happens. $$$ lost in depreciation.

Im with you on this.. Ive been cursed with my HREs. One wheel off my Saleen was destroyed by the machine when it "malfunctioned" and had to be rebuilt by HRE,, took 3 months,, rockn the donut spare! Every time I ask new places if they can mount tires without fukn up my wheels, they insist they can,, and Ive tried several spots. A couple weeks ago, they broke the hidden valve stem completely off with the "touchless" machine, so they had to order them from HRE and I'll have to go back to get them put on. AND,, when they were putting the wheels back on the car, the retards with the lug wrenches chipped all the paint around the lug wells!! Was so fn mad! I could go on and on with stories of misfortune for all my HREs.. Cursed!!! :bomb:

I finally picked up the V today and just mounted the Forgestar CF10 wheels this evening! I apologize in advance for the crappy low light cell phone pics; you know higher quality pics are to follow!!

The fit of the fronts is just about perfect. Maybe sits 1 or 2mm further out than "perfect". The rears sit out about 5 or 6mm further out than "perfect". I'm not sure if they changed the 345-25-20 Invo mold or what, but the rim protectors are about 1/4" wider than I had anticipated based on my interwebs research. Clearance on the inside of the rears is great. I can fit about an index finger thickness between the edge of the wheel/tire and every potential contact spot. Only area I see possibly being an issue is the wheel well liner on the front/inside of the rear wheel. It is rather flimsy and is kinda close to the tire, so I'll keep an eye on that for signs of rubbing; this is an extremely easy fix with a rivet or the like (if there's an issue at all). Its damn close to the correct offset, but just shy of perfect!

I may look into slightly pulling the lip of the rear fender out several mm to make them look more flush. Any recommendations?? I was thinking of just placing a 2x4 on the inside, throwing on some leather work gloves, and just coaxing it out ever so slightly. Am I f'ing crazy or is this what any shop is going to charge me a couple hundred bucks to do?

This is now the new standard for coupes 20"x12" +45 rear and 20"x9" +35 front!!
Fitment is Awesome, a little rim outside the fender makes it look sinister on any car!
If it rubs just go down a tire size for a mild stretch, it will enhance the look as well. i don't think its worth rolling the fenders.

Wish these cars could take more offset for an extreme concave look.

Now I need to translate this to a sedan fitment, maybe down an inch in the rear, and sell my current wheels.

Sorry d00d, wheels sticking out make it look like a toy car or dragster wannabe.

I appreciate you pioneering this and I'm not trying to be mean as you've been a member of the community for a long time. It's just this is a peeve of mine. If it was an 11" wheel with 325s, I think it would be perfect.

Did you say you have a spacer in the back? Could you bring them in?

I would not have posted it here if I wasn't looking for feedback, both positive and negative. And for the record, I absolutely agree with you. There are no spacers. Its all wheel.

I plan to have an alignment and add a degree of camber to gain a few mm's and then, if I absolutely have to, have the fenders pulled out several mm's.

TTuned
05-23-12, 03:06 PM
Spacers are like stuffing your pants, hahaha. A reason for custom ordering wheels and spending big $$ is to get the perfect offsets for a nice stance that an off the shelf wheel just can't offer, taking full advantage of the wheel wells.
the aggressive stance trend isn't for everyone, but it really makes a statement, $$ well spent.

I'd trade my HRE for something with lower offsets like that!

Hello everyone,

Firstly and most importantly, I would like to thank LV_V for bringing this challenge to us. He has been incredibly patient while we worked out some of the issues that comes with fitting a setup like this. We have all of the "bugs" worked out thanks to LV_V's excellent feedback.

We are now taking orders for this setup for the CTS-V Coupe. If anyone has any questions you can contact me by phone at 1-888-554-7755 or by email at paul@howeyindustries.com

The CF10 20x9 is approx 24lbs and the 20x12 is approx 26lbs. I do not have the data on the stock wheel weights. It really isn't possible to bring these 20x12's with the 345's in much further. We can definitely do fitment on a 20x11 that is more inside the fender.

I'm glad LV_V decided to go for this! It is a fitment that has been talked about for awhile but I'm not aware of anyone trying it on a coupe without body mods.

Could you run a 335/30/20 ps2 with this setup? and would it fit nicely and have more sidewall?

Paul@HoweyIndustries
05-26-12, 01:34 AM
Could you run a 335/30/20 ps2 with this setup? and would it fit nicely and have more sidewall?

The 335/30/20 would be 1" larger in overall diameter when compared to stock diameter. While this not a drastic increase, you will most likely need to recalibrate the speedometer. The 345/25/20 is almost exactly the same overall diameter as the stock 285/35/19. There is only a .2" difference.

However, if you look at the image that LV_V posted of the rear wheel on its side, you will notice that there is a decent amount of "overhang" on each side of the wheel from the 345. This is primarily what you are seeing "poke" outside the fender. Are you looking for a tire size that will be more inside the fender?

If I could do it again I would add 5mm to the offset in the back, but with the curves of the coupe's body you really can't tell it's poking out unless you are right behind the fender and looking for it. I love the look and the traction is just sick.

Lowered on Eibachs. Zero rubbing. Nitro Invo is thinner than most brands. Don't think a 335 Dunlop would be thinner, but we won't know until you try ;)

What would you recommend for a similar stance on a 2012 wagon.

Paul@HoweyIndustries
06-21-12, 11:27 AM
What would you recommend for a similar stance on a 2012 wagon.

Stance is all relative to fitment. Are you seeking something that has the aggressive/flush "look" like LV-V's CTS-V Coupe? If so, this can be achieve with virtually any width wheel and the appropriate offsets. For the CF10 we generally do a 20x10 on the wagon and sedan. With the F14 & CF5, we get up to a 20x11 but most of our customers prefer the 20x10.5. Again, all of these sizes can be made to fit the vehicle in the same aggressive manner that provides a similar stance and look as LV-V's Coupe. If you have any other questions, feel free to post them, call me at 1-888-554-7755, email me directly at paul@howeyindustries.com, or PM me. I'll be glad to work out a fitment that will get you exactly what you are looking for.

I would like to have my tires and rims as wide as possible without sticking out of the wheel well. Flush to me means that there is a chance that it will rub with the fender without rolling. It could just be semantics. I would like the wheel and tire to fill up the wheel well. I want a deep concave look on the rim. The tire and rim should look like when hitting a bump it will be abosrbed with in the wheel well. IMO BMW does a good job of achieving this look on their stock cars.

FWIW I have not rubbed the outer fender at all with my setup. I have, however, VERY slightly rubbed the inner fender once when I hit a small bump on a high speed banking turn on the freeway at 80mph. This was without sport mode suspension on. I now click sport mode on as habit when starting her up.

Thank you for the compliments. This has been a great project to work on. I started a new thread a short time ago regarding the information you are requesting. It can be found here:
http://www.cadillacforums.com/forums/2009-cadillac-cts-v-appearance-mods/261296-forgestar-wheel-fitment-cts-v-coupe.html

I still need to update the thread with Tire specifications, which I will do shortly. However, please note that we do not publicly post our offset data. The offsets have taken a great deal of time and energy to collect. We do share the offsets privately with out customers but these specs are what make our fitments special and separates us from the competition :)

Since my prices are below the approved MAP pricing from Forgestar, I can not openly post prices. However, I can say that a set of 20" wheels will be less then 2k for the set with free shipping within the United States. For specific price quotes, please forward me the wheel model, finish, and size you desire by PM or to my direct email at paul@howeyindustries.com

Please let me know if you have any other questions and I will do my best to answer them.

Just wanted to take the time here as well to thank Paul and LV_V for making this thread and taking the time and effort to do something no one had done before! I took the thread down to my local tire shop who I have a 10 year relationship with. They've done custom Wilwood's on my Titan and a host of various other custom stuff. Jason (my dealer) called Paul to talk the specifics and he was more than helpful even without the sale and I very much appreciate that! Even though I am not buying from him I can't help but recommend him to anyone after that kind of customer service. My order is in for the same fitment same tire, going with Niche Forged Monoblock's Targa T-14's, a real similar style to our stockers. http://www.mhtwheels.com/mht-luxury-alloy-wheel.cfm?id=3473 Not sure if that link will work they use a lot of adobe. If not this one will... http://www.europeanautosource.com/product/mht-niche-targa-t14-monotec-wheel

I am having them painted to match the Black Diamond. And now the waiting game begins... ugh, I am about 5-6 weeks out.

LV_V how has the ride compared to the stock PS2's? Road noise, comfort, traction? I have not been happy with them at all, especially with only about 13-14k miles out em. Can't wait to see these bad boys on there. I'll try to get weights on both the Niche and stock rim.

Just wanted to take the time here as well to thank Paul and LV_V for making this thread and taking the time and effort to do something no one had done before! I took the thread down to my local tire shop who I have a 10 year relationship with. They've done custom Wilwood's on my Titan and a host of various other custom stuff. Jason (my dealer) called Paul to talk the specifics and he was more than helpful even without the sale and I very much appreciate that! Even though I am not buying from him I can't help but recommend him to anyone after that kind of customer service. My order is in for the same fitment same tire, going with Niche Forged Monoblock's Targa T-14's, a real similar style to our stockers. http://www.mhtwheels.com/mht-luxury-alloy-wheel.cfm?id=3473 Not sure if that link will work they use a lot of adobe. If not this one will... http://www.europeanautosource.com/product/mht-niche-targa-t14-monotec-wheel

I am having them painted to match the Black Diamond. And now the waiting game begins... ugh, I am about 5-6 weeks out.

LV_V how has the ride compared to the stock PS2's? Road noise, comfort, traction? I have not been happy with them at all, especially with only about 13-14k miles out em. Can't wait to see these bad boys on there. I'll try to get weights on both the Niche and stock rim.

Glad we could help! I'm all about seeing great cars with great setups even if they do not come from us. I can't wait to see some pics :) Should be amazing.

Ride is in my opinion very comparable to stock with the Nitto Invo tires, granted I only had the car for 24 hours and 500 miles before swapping out the stock PS2's for the Forgestars with Invos... Zero complaints with the ride quality. The traction is noticeably better. I can spin them if I drop it in 1st and a little in 2nd, but little to no spin above that. The 9.55" pulley may change that...

The 335 30 20's are, in my opinion, going to be too large for the wheel well, especially if you're lowered. Try it and let us know, nobody has done it yet :)

Have you considered sticking with 19s and running the Michelin SS 325/30 in back and 275/35 up front? Not sure 10mm will make a difference, but just throwing it out there. I have seen this setup work on a sedan with modified stock wheels.

Lol that's why i asked there is no good tires here in my country so i can't change them when i don't like them .

if the 335 is not the way to go ill do the same setup as you :)

Sorry for the late reply to this. The 335 would not be the issue but the 30 profile puts the wheel at an overall diameter of 28". You want to be as close to 27" as possible. Now the 335 is only an additional .5" on each side of the wheel, which is not huge. However, based on the vehicle being lowered and the aggressive wheel, I would not be able to say 100% for sure if there would be any issues.

Paul,

I can take this offline, but was wondering if a 325/30-19 would work with some of your wheel options? This, coupled with a 275/35-19 up front would put both F/R ~26.6" tall... pretty close to stock rolling diameter. My sedan is not lowered yet.

Thx.

Wes,

I just responded to your email regarding this but I will also post here to better serve the community members who have the same question. In my opinion, the 325 is too large for a 10.5" wheel. The 26.6" overall diameter is definitely within spec and would work fine. The 325 (325mm) of width is the issue. It comes in at 12.78" wide. This is a lot of extra tire on each side of the wheel, especially for the Sedan. The tire would definitely poke outside the fender, which is not the primary concern. I would be more concerned that the extra tire will rub the inside area and suspension. A 295 or 305 would be the maximum I would run on the Sedan with a 10.5" wheel.

I am following this thread as I see alot of great info. I will be getting with you guys in the near future once I pull the trigger on the 12 CTS V coupe. I am running the Nitto Invo on my Grand Sport and really like them I will also want the largest wheel/tire combo to fit in the wheel well with aggressive look.I really like the Forgestar wheels. Decisions decisions.

Sounds great! The wheels do take 4-6 weeks to produce. Just in case you want to place the order before the car arrives like LV_V did :thumbsup:

LV_V wasted no time getting his wheels installed haha

All ...
I am a little confused by the 20" x 9" fronts having a +35 offset.
Based on the digital data & forum searchs, the standard fronts are 19" x 9" with +51 offset.
Why are the 20" fronts offset reduced, pushing the wheel outboard by 16mm?
Is it simply to clear the brake caliper?
If we are having custom rims made, would we be better to run 9.5" rims with an appropriate offset and "spoke" profiles to clear the caliper?

The 20x9 +35 offset is simply to create a "flush" fitment with the fender. We can go with a higher offset and still clear the brakes but that was not the desired "look" for this particular application.

You can definitely do a 20x9.5 in the front, but not with Forgestar. All of Forgestar's 20x9.5's are Deep Concave and will not clear the V Brakes. We are limited to 9" front sizing with the Forgestar brands.

Just picked a set if cF10s for my coupe. came with Michelin Pilot Super Sports on 20X12 and 19X9.5 and 325/25 & 265/35.

Previous owner said stock front lug bolts stuck out about 1/2 and inch before the nuts. How much do your stick out if any?
