Wow - today was a good day, I went to a fantastic car show and won a raffle for a serious discount on a set of DPE Engineering Wheels. They had a vairety of Porsche and BMW's on display showing off their wheels. DPE makes some very nice 2 and 3 piece wheels for many cars and can build to any offset including the 08 CTS. I assume that I will need a 120 bolt pattern with a 34 offset...

I am planning to go with a 20 inch wheel with a 10" rear (provides a 4 inch rear lip:)) with an 8 or 8.5 in the front.

Here are the two choices that I would love your feedback on. It would be great to try and PhotoShop these onto a Thunder Grey CTS if any of you are pros?

OPTION #1
2-Piece
Model# R07S

Which ones do you think will look best on an 08 CTS?

WoW! Congrats on the win! I think the second set on the black 3 series look great. I'm not great with photoshop so you'll want to wait for someone else to do it ;) If no one does, just post your rides pic and I'll be happy to give it a go.

Cheers

Thanks Hemo....Yeah I was pleasantly surprised! It is so hard to choose wheels without seeing them on the CTS itself :).

the MB one will be the best looking

if you dont mind, we can do it together, see if we can get more discount by doubling the order, you from southern CA right?

You'll need a 40mm offset for 10" wheels. I like the twin 7 spokes.

Correct, and yes that is a good idea. They are located in Costa Mesa, CA. PM me your info.

40mm offset?? Are you sure? The people that I have spoken with all tell me 34mm offset. Does anyone have further thoughts on this?

Your Photoshop Request semi fulfilled...

I also agree that the seven spoke looks better on the cts. I went with a similar style as well. Nice choice!

i really like those. i am also looking for new wheels. what is the price of them? maybe we could get a group buy or something?

Nice job....I think these look solid on a CTS. :)

Great chop, but the proportions are off. They look like 22-24 inch rims!

if the owner would answer my e-mails we would have a few group buys running right now for members of the site.. but no one returns e-mails

Let's apply some pressure, I have had multiple PMs from members who want to order staggered wheel setups with me. Can you PM me your info and I will give you a call?

Also, can anyone confirm what offset I need so I can maximize my rear lip w/o rubbing?

do they make those wheels in 18's and 19's or just 20's and up?

Correct, and yes that is a good idea. They are located in Costa Mesa, CA. PM me your info.

sorry havent reply you soon, since i hvnt visit the forum in the past few days.
i actually went to costa mesa yesterday. i will pm you my email now.

I have an email into the wheel mfr to get an understanding of the right offset for the 20X10 staggered setup. As soon as I hear anything I will let everyone know.

WOW those will be awesome:bonkers: I would probably stick with the 2 piece for the simple reason that you can avoid having rivets

I dont think you will be able to get a 20x10 setup...20 x 9.5 is also impossible unless you roll and fenders and even then, it will still rub

I dont think you will be able to get a 20x10 setup...20 x 9.5 is also impossible unless you roll and fenders and even then, it will still rub

Actually you can mount 10.5's in the rear of the 08 CTS based on some of the research I have been doing on this subject...its all about the offset and type of wheel. Some of the new one piece and three piece wheels with the 120 bolt pattern can achieve a 10" rear w/o any rolling and can accomodate lowered suspension as well. D3, Wheel Executives and HDM who are all board sponsors have achieved such results.

Really? At what offsets is this possible? When I look at the clearance of the wheel well, I dont see this as possible...Perhaps someone can educate all of us on how this is done...It would open a whole lot more possibilities in wheel selection.

Hey there.....I am a little curious too about the wheel offsets
..
I went to this so called "wheel expert" here and he said its better to stick with 8.5 at the back just because there is not room in the rear to play with..
unless you roll the fenders

however I do want prove him wrong...so a 10.5 would be the maximum width without rolling the fenders?..

I am looking for a 20inch set with 9.5 width or more at the back ...I just wanted to know from you guys whats the safest maximum width I can go at....and also what offset

Thnx alot guys

If this wheel expert told you that you can only run 8.5 in the rear.... RUN! You can most certainly run 10.5" in the rear. We have done it time and time again.

Show him this picture and see if there is any room in there for 10.5.

By the way this is a 295 in the rear!! No mods, no rubbing, NOTHING. Just a great fitting wheel.

So what size 20 can i put for the front and what is the rear size. Offset. i want to put some Vertini Hennessey 20x 8.5 front and a 20 x 10 for the rear, Will they fit and what offset is needed? Also what tire can i mount.

Dr. Design show us more pics of that blue CTS! looks crazy!!

By the way, while wider rear wheels and tires may fit and look great, with the stock suspension it will alter the handling balance and induce more understeer. The adjustable suspension offered by D3 can certainly ameliorate this, but if one doesn't want to go to that level, I would consider keeping the wheels and tires equal front to rear, whatever sizes one chooses. This car certainly doesn't need more understeer.

Hey El Guy- nice wheel choice, however it is not as simple as ordering a 20X10 in the rear and a 20X8.5 in the front (which is the right spec). Most wheel companies will need to custom make your wheels using the correct offset otherwise you will have rubbing and fitment issues. It goes way beyond bolt patterns...D3 can explain more, but this is surely a topic that I have spent hours researching. I have been on the hunt for the "right staggered setup" for the CTS for some time now...

ok i got 20's on my car with 8.5 with 2 inch lip in the front and 10 with 3.5 inch lip in the back . would recommend going with a 3 inch lip in the back cuz my rear wheel is .5 inches out the cars fender. you can go ass wide as you want but make sure ur lip is 3 inches

If this wheel expert told you that you can only run 8.5 in the rear.... RUN! You can most certainly run 10.5" in the rear. We have done it time and time again.

Hahahaha...thats what I did...I RAN!!:D...this "expert" also said that if he did put 10.5 he would have to put thinner tires...but clearly 295 says enough ;)

I just need to know the offset range though...also looking for a 20" wheel which has the spokes runing all the way to the edge, or rather without a lip so it appears as big as a 22inch.

Here you go...

Dr. Design show us more pics of that blue CTS! looks crazy!!

what size rear and front wheels are you running??
20x10.5 offset???? with what tire size ???
20x8.5 offset??? with what tire size???

also what about 22's ??? just got the car 2 days ago

Here is the question of the day...can you run those 10.5's with a "real" drop?

D3, there still appears to be quite a bit of fender gap on that car even with the coilovers, so don't you think a 1.5 - 2" drop with your 10.5 setup will rub in the rear...and potentially the front given your offset?

Hello,
Well that is a good question. The quick answer is YES. You can certainly lower the vehicle more than what we show here. The tires do not rub, nor do they go past the line of the fender. So if the vehicle is lowered more, you will not have a problem.

Thank you,

Dr. Design: What are the wheel and tire spec on that Blue CTS?

Hello,
The Blue CTS uses a 19x8.5" front wrapped in a 235/35/ZR19 and 19x10.5" rears wrapped in 295/30/ZR19. The tires used during this test session were the Toyo R888's. So our tire sizes were a little limited given the production cycle of this tire. We would normally run a 9" wide in the front with a 245 or 255 tire.

Please let us know if there are any questions.
Thank you,

Thanks for the info. I was planning on getting the same setup but in the front I was thinking about 19 x 9 and the rear 19 x 10.

Hello,
That would not be a problem at all as the vehicle will support a 19x9 in the front. Obviously the rear is not an issue at all. Please let us know if there are any questions.

p.s. We have been getting a lot of requests for our wheel offerings to be photoshop'd on 08 CTS'. If you have something you would like to see, please let us know and we can see about doing it for you.

I totally respect and appreciate what D3 has done for both this forum and the CTS. I really think that they along with some other leaders in this community are giving us casual owners a lot of GREAT ideas and options for our cars. However, I have watched Dr. Design dodge the offset question a multitude of times because if we have the offset, we can utilize other vendors. If the D3 products/wheels are that far superior, then they would be able to provide an offset recommendation the first time they were asked. I'm not hating on you guys, you guys do a TON for the forum, but not knowing the offset when you know everything else about the vehicle is pretty silly. Have confidence in your product, tell us consumers what the offset is and tell us why your wheels are the way to go.

Actually, I think it is inappropriate for anyone to expect a vendor to help them purchase somewhere else. Kind of like going into one store and asking questions about a product they intend to purchase from a competitor.:thepan: The real question is why you would buy from anywhere that couldn't provide you the answer themselves?:yup:

IMHO D3 has been more than kind in trying to help out on generic questions not directly related to their product. If/when I purchase exhaust or intake options they will be first on my list. They are also a forum sponsor.:thumbsup:

First, I want you congratulate you on your clever use of the smilies.:highfive: Second, I want to remind you, and your "real question", that a misinformed vendor and buyer is what started this thread. Do you recall? An informed consumer is ultimately what a quality vendor wants, not hostages. If we don't know what an offset needs to be, then how can we evaluate one vendor against another. If that's not important to you, then I've got all kinds of stuff I would like to sell to you!

Again, I think D3 is excellent in their innovation and forum support. I like their body kits and performance parts, but I'm not thrilled with their wheels. Hopefully that doesn't hurt their feelings because customer feedback is the key to business growth and success (I'll save Business 101 for later).

All it takes is a couple people who have wheels to post the offset they have and than it's no big secret. Go on any other forum and I can damn near gurantee someone will tell you the offset to fit that car. Search the corvette forum for any gen and you'll find out within minutes.

I also agree that D3 has helped and ton and developed lots of exciting parts but they should be afraid to hide their technical data. I understand there are lots of pirates out there who copy others but like I said once the info is out, everyone and anyone can find it. How will D3's sales guys know if they are selling you the correct part if only the engineers have the correct info. His answer was a cop out.

If it is so easy to get, then provide the information to the forum. I'm getting tired of you being so secretive.:lildevil:

Hello,
Thank you for the comments. Although providing everyone with the offsets would be helpful, it typically isn’t required if someone is interested in buying our wheels. Unfortunately we have had "situations" in the past that has made us rather reluctant to provide too much information. That’s the reason we post images of the wheels on the car. Hopefully you will notice that they are a nice tight fit. Providing you with the offset measurements isn’t going to show you that. We are more than happy to help educate the forum members, but giving out our data shouldn’t be expected of us.

Sorry if some of you don’t agree, but we can’t pay our engineers and technicians to gather this data just to give it away for free on the internet. We just want to assure all of you that if you purchase wheels through D3, they will be correct the first time and you will not have any fitment issues, guaranteed! If the wheel company you are dealing with cannot guarantee that, then you might want to look somewhere else for your wheels. Please let us know if there are any questions.

You're the man! I'm going to start working on a calculating hypothetical offsets based on this. I don't have the tools and access to the hardware like others, but if I can figure it out, it has to help someone. Again, nice work digging this up (I recall seeing it at some point).

If a person buys a set of wheels from D3 and he post up info on the rims including the offset of the wheel, whats the difference?

I have 2 more people to search. If I find any info from the other 2, I'll post it up.

will post what i find when i get to sema in 2 weeks i havent put much time into taking a look or calling anyone in the wheel business just waiting to see if i want 20s or 22s its a very high offset i think about 40

There is no difference. We (D3 Cadillac) just will not post that information. If someone buys wheels from us and wants to post the information, then they are free to do so. There are a lot of companies that will "borrow" offset measurements based on other companies research not knowing why the measurement was the way it was. If you want to run big brakes at a later date (i.e. D3 Big Brake Kit or the 09 CTSV Big Brake System) we have all the measurements for it.

Sorry if you guys think we are dancing around the question....

call superbuy tires or wsiaz.com they will know

Yeah they have it. We just provided them with some data for an STSV....

call superbuy tires or wsiaz.com they will know

ok sat down now make some calls to guys i know in the wheel business the centerbore is 70.3 pcd in 5x120mm offset is 35 to 40mm

Well i have been doing some research. It looks like we need in the front 20 x 8.5 34m offset, Tire 245/35/20 Rear 20x 10 Offset 42M Tire 275/30/20
