First, here is the obligatory "I did a search but could not find what I was looking for" statement. If this topic has been covered and I missed it, please post up the link.

My summer wheel setup is PIAA Super Rozza 19x9 +25 offset front and 19x10 +25 offset rear, with 245/35/19 and 275/35/19 Toyo T-1R respectively. In my opinion the rear wheel offset is a little 'wussy' considering the 10" width. The wheel still looks a little tucked. I would like to push the wheel farther outward using a spacer, but not so far as to cause rubbing. The setup I had in mind was like a typical Volk GTS size that is 10.5" wide with +18 offset. I calculate that if I put in a 13mm thick spacer, making the wheel offset effectively +12mm, it would be about equivalent to a wheel that is 10.5" wide with about +18mm offset. I double-checked myself using an online offset calculator and it checked out.

Now, since I remember there being some debate on whether the 10.5" +18 with 275/35/19 tires would fit without rubbing, and since the 275 tire on my 10" wide wheel will be less 'stretched' than a 275 tire on the 10.5" wide wheel, I am thinking I will use less than 13mm spacer to be 'sure'. So assuming I use an 11mm thick spacer, the offset of the wheel would be effectively +14mm.

Soooooo, does anyone have experience running 10" wide wheels with +14mm offset (give or take a millimeter) with 275/35/19 tires? If so can you offer some pictures? I know the amount of negative camber will also affect the spacing at the top of the tire, so if you post pics please tell how much negative camber you have, or what type of springs/coils you are running, how much drop, etc. FYI I have Hotchkis springs which is one of the more mild drops out there, and there isn't too much negative camber.

I think my original post was pretty convoluted, so here is the abridged version:



Using a 15mm spacer, I will have 19x10 +10 offset, which sticks out from the wheel hub just about the same as 19x10.5 +16 offset (in terms of Volk typical 10.5" wide sizing). Or, using a 10mm spacer, I will have 19x10 +15 offset, which sticks out roughly as far as 19x10.5 +21 offset. So my question is, can anyone post pictures of any of these sizes on the rear wheels with 275/35/19 tire size? And also please comment on whether fender modification was required to achieve the fit without rubbing. Thanks in advance...

Why don't you just roll your fender and run a 20mm spacer for a real flush look? It won't rub either

I thought about that but since I am only lowered on Hotchkis springs, there would still be visible gap between the top of the tire and the bottom of the fender, so while rolling the fenders would allow for full suspension travel, it still wouldn't look quite right to me. Also, I would like to avoid rolling the fenders if possible, so I am looking for the farthest out I can go without rolling.

I should have also added a disclaimer that this is all driven by aesthetics and not functionality, but I am curious to feel for any difference in handling from pushing the wheels farther out.

How would having the wheels sit further in the fenderwells make this any better? Its fine if you don't want to roll your fenders, but not for this reason

you really think pushing the wheels out 13mm really effect handling? if you do it, you should be doing it for looks not for handling.

I used to run 10.5 +22 rears w/ a 15mm spacers w/ 275/35/19's and was rubbing over small freeway bumps even w/ a fender roll on both sides...switched to 5mm spacers w/ no problems.

im dropped 1.5" and running 10.5+ +24 rears with a 20mm spacer and i still have plenty of room. thinking of going wtih 295/30/19's to try to fill up the gap.

Got pics...? How much are you rolled..? sorry for the thread jack...

LOL I'm not sure what I was thinking either, actually. But bottom line is, I want to avoid rolling the fenders.

and @ Nexx, I understand that this is not a modification to alter the car's handling....in fact I even said that it was for aesthetic reasons, and that I am curious to see if the handling is affected at all. Maybe I worded it weird...

ill try to get some tomorrow. looks like i need another .5 drop or more positive camber or bigger tires.

if im not mistaken, someone posted here not too long ago bout 10" on 15mm with 285 without rolling fender...he even said that going over 15 on 285 with 10" is a little too much and will require fender rolling....i think 10.5 +17 is perfect on 275...again its just my opinion...

I would go with a 10mm spacer if you don't want to roll the fender. I rubbed with a 285 tire on a 10" +15 wheel, lowered just over 1" on Tein Basics. With less of a drop and a 275 tire, you should be fine. Also, if you go anything over 10mm IMO it will make the car look weird with the rear fitment much more aggressive than the front.

I am starting to lean toward the 10mm spacer. I think it will be enough to achieve what I am going for, without rolling fenders. Your point about the rear looking too aggressive for the front is a good one too...I am thinking that I will put the 10mm spacers on and see how it looks, then go from there. By the way here is a picture of what my rear fitment looks like now. I am thinking the 10mm spacer will be a subtle but nice touch:

EDIT - Just to clarify, this picture is without a spacer.

Youre going to rub. But try and see. Thats the only way to learn I guess

I rubbed with +22 offsets. But that was with 285/35/19's
I think most guys who run +17,18 offsets on their gt-s roll their fenders too.

How wide were your wheels with the +22 offsets?

Gooey

iTrader: (18)

10.5. They rubbed a LOT. To the point where I only drove less then a mile and it already took chunks out of the side. Put back on my spare wheels and rolled my fender the next day.

Wow, thanks for the heads-up. I think I might end up mounting the wheels and taking some measurements before I buy any spacers. The issue is that the same size will have different clearances on cars with different amounts of camber, it's really a case by case issue.

For your reference I am lowered on eibach pro-kit ~1"-1.2" drop
And I have my rears aligned to factory spec.
