: Offset Dilemma...

(I have contacted D3 but have yet to respond)

I'm looking to lower my 05 STS, using D3 lowering springs, and going from 22s to a staggard set of 20s (20X9 with 35 offset & 20X10 45 offset)

With my 22s theres a massive gap in the rear before it being lowered but in the front it's pretty flush therefore i figured if I wanted to drop it i would have to go with a smaller size wheel if i want to stay away from doing any further mods besides the springs.

To my understanding; the higher the offset the closer it is towards the strut/shock/inside wheel well. While the lower the number the further out it sticks.

My question is, with the 1.5" drop all around, will 20X9 35 offset with 245/30R20 fit in the front with flush status and no worry about rubbing while turning or things of the sort...

And in the rear will 20X10 45 offset with 285/30R20 fit without rubbing or having to pull out the quarters or anything like that? Or is 45 too much of an offset and 43 or 40 would wrk better for the rear?


Thanks in advance!

Ive contacted D3 and with an offset of 45....there will be no rubbing at all. Even with my 22x9 in the rear i didnt have to do nothing at all after i dropped mine. You will be fine without any mod to the fender at all.

Thanks for the info!

So is my tire choice good?? Should 245/30R20 in the front look good? How bout 285/30R20s in the rear?

:ill:

At what point will I have to consider spacers? :suspense:

Honestly you wont need spacers. I am currently having an air bag system built for my car, and really the only time to put spacers is once the car is dumped and the wheels camber.

Sweet!

Well thanks to the peeps who tried to help! Very informative!

It's time for some trail and error!

this is what I have now...offset is 13 all around I believe I could be wrong...

wheels are 22X9.5 with 245/30R22 tires...

Notice the rear gap :annoyed:

looks good man...definitely should lower it to get rid of that gap.

Yea, I hear ya...I just don't want to rub; as of right now the fronts rub just a tad when turning and at a certain angle, nothing horrible but I would imagine it would get worse if i lower it and keep the 22s therefore I want to go 20s but with a nice stagard set with wider tires in the rear!

I disagree on the tire/wheel gap. I believe the current setup displays beautiful proportions.

Now, it is your car. if you want a squatty look take her down a couple inches. In my opinion, it wouldn't look any better and would destroy the geometry of a very good suspension while making accurate wheels allignments a thing of the past.

Thank you for the words of wisdom!

It's gettin tough now...I'm not sure what I want to do...I'll just have to kick it around for a bit...

I'm 21 so a part of me wants a "meaner" stance for the caddy yet another part of me says "whats the stance without it's roar..." you know what i mean, it's only a V6...Even though I'm somewhat young I feel like these wheels bring to much "look at me, I'm flossin'" attention rather than "a nicely done mean looking stance-respect" idk lol I'm just blah blah now...

I'm open to other opinions if fellow caddy owners care to share...

On another note my current set up is +13 offset therefore it gives me the lip I have now...so if I want a +45 offset it'll give me less of a dish/lip...I want the wheels to cave in a bit so i'll be looking for some wheels with a lower or negative offset...

Different strokes for different folks. At 53, I may not be an old fart but my AWD wears 235/50R18's on all corners because I'm more concerned with ride and long quiet tire life than looks. But I do think the OEM 18" wheels look pretty good and lower profile tires do have better 'turn-in'. The stock STS has a lot of style. The only car it can be confused with is 'little brother' CTS.

Since we have real Winters and my wife is a loveable lead-foot AND kinda cheap, her stock 17" wheels (2007 RWD) wear Blizzaks November-April. That allows Summer tires for even more fun!

lol I see, I wish I had the V8 AWD, that would have been awsome! But when I 1st laid eyes on the STS 3 years ago, I wasn't aware that they could be found an AWD V8s!!

Anyhow, currently I have my OEM/stock 17s on right now and I have been considering getting some other OEM caddy wheels that are 18s but I can't find any with the same bolt pattern as my STS...JE5 brakes wouldn't change my bolt pattern would it??

All in all one day I may trade this bad boy in for the AWD but till than I want to give the caddy the look I'm going for...thanks once again!

I've come to find out, since i just started going some research on em after having em for three years "faceplant", they are considered a cheap brand lol they are called "Hoyo H2" can be found on wheelfire.com or something like that lol and yes I believe they can be bought as 18s-24s...

They don't look too bad, I've seen alot worse lol

I think all the STS 5-bolt hub/wheels are the same.

Sounds good...

I have the 5X115 bolt pattern...V-series STS or AWD have different bolt patterns do they not? Along with the newer CTS and even older ones for that matter...

Is there any Caddy that has OEM/Stock wheels that are bigger than 18's and have 1X115 bolt pattern??

RWD & AWD STS are both the same 5-lug hubs & wheels. V's and models with 6-piston caliper brakes have the 6-lugs. Different Cadillacs use different wheels; I think CTS may be different.

Cool, thanks for the info...

Not sure if anyone noticed but my understanding on offset was wrong...A member from another forum cleared it up for me...

"First off, im positive the whees will fit.

Secondly, you have your lower and higher numbers reversed for offset.

lower numbers push the face off the rim inwards (numbers like +20, +10, -5 etc...)

Higher numbers will push the face of the rim outwards (numbers like +40, +45 rims like your 22's probably are +40's)"

Here is a +25 rim with a nice lip

But you see here is a +15 which sticks out further than the +25 wheel even though it shouldnt, is all about where the rims meet the rotor.

Here is another +25 rim on the rear that sticks in quite a bit.

http://i768.photobucket.com/albums/xx328/sergeNcoop172/attachment-1.jpg

This is a -15 rim, that lip is way to crazy and probably would not fit your car. see how the face of the rim is at the very back of the rim.

And this is a 19 x 10 with a -7 offset that was on a 240sx, if this huge rim can fit on a slammed 240sx, im sure your caddy will fit the 20's with no problem. Again these have crazy lips.
