Hi i have a question about Enkei and after using the 1010tires calculators i get the Feeling that RPF1s and not going to work out too well but I want to check here first, my car 16 IS200t with F-sport, I am considering running Enkei RPF1’s like @dnasians (or possibly Enkei’s new PF05 or T6S as they can be found out to a +45 offsets) . But unlike him I am wanting to run them in a square set up. Based on the research here I am looking to run 18x8 or 8.5 with +40/45 offset because of spacers. For RPF1s I am considering anything under a 9in width because the spoke design sits further out from the brake caliper on sub 9in barrels. Tire size for now will be 235/40/18 (as I have a good new spare set) then after that I will go wider with 245/40/18. I know from @dnasians post that I need to run a15mm spacer on the front to clear the F-sport front brake calipers and longer wheel studs. But given that at the RPF1s in 5x114.3 the max positive offset they make is only +40mm, Given that I have to run a 15mm spacer that puts me negative back to +25 and correct me if I am wrong that seems way too far out on the front for any lowering as I plan to install lowering springs like S-techs that have around an +1inch drop. I am not at all opposed to going with a different brand especially if i can around having to run spacers, i just like Enkei's designs.

Let's assume the worst and it doesn't, then you could run a 10, 15, or 20mm spacer which should have the studs built in, so no need to replace the studs on the car. You would simply bolt the spacer to the car, and the wheels to the spacer.
Typically +25 is a little too much offset for the wheels, but you also have to account for how wide the wheels are...for instance (to use extreme examples), if you had an 18x6 rim, then +25mm is the distance from center (center being 3 inches) of a 6 inch rim. If you have an 18x10 rim, then +25mm is the distance from center (center being 5 inches) of a 10 inch rim. So the +25 is only as important, or relevant, as the width of the rim. Many run 20mm spacers on stock F Sport front rims, which are 18x8 +45...so they are right at +25mm offset at that point.
Typically for the rear F Sport wheels, 18x8.5 +50, a 15mm can fit without issue, some even manage to squeeze a 20mm on...but once again, that rim is 8.5...reduce that to 8 inches, and 20mm should fit no problem.

If you're going to run a 18x8 +40, depending on spoke design it may or may not clear the wheel.

I did check out the bolt-on spacers, but i am trying to avoid cutting/shaving the stock studs, If anybody out there knows of some wheels that i could run (any brand) in that configuration, that out of the box will clear the front F-sport calipers, please let me know. I have been looking around i believe there are a few Volk/Rays that will clear. Something minor like a 5mm spacer is fine, I am just trying to avoid buying studs if at all possible as i only plan on keeping this car about 2-3 years. Thanks

Even a 15mm spacer should be fine. You really just need to see the back of the wheel to confirm.
The folks that have put 20mm spacers on the front of the IS with stock F Sport rims didn't modify the studs...as far as I know.

Hi there! Im new to this forum! Currently selling my 2014 Audi S4 and planning to get a 2017 is350 awd.
Im thinking of this setup:
Wheels front/rear = 19x9.5 +40 squared
Tires front/rear = 255/35-19 squared
Is this gonna fit? What is the maximum offset for front and rear?
Sorry if im asking dumb questions im just confused most of the guys here are running a less wider wheels on the front mostly 19x8.5 and less taller tires on the rear like 30-19 instead of both 35-19 squared.
Why is that??
Thank you for the patience im just trying to educate myself here on this new platform.

For the front, most do run 19 or 18 by 8.5....usually around +30 to +35 offset. If you can find a 9 inch rim, that would work too.
When you get into 9.5 on the front, it then becomes an issue of the offset being enough to not hit the steering knuckle, and not rubbing on the fender liner. The margin for error is really small.
There is one member that did a square setup on 18x9.5 +35 lowered with no issues...but that may have been a case of everything lining up perfectly to make it happen.
For the rear a 19x9.5 +40 will be just fine. You could likely put the same rim on the front, but you'll need to use a small spacer. Also you need to consider if you plan to lower the car as well.
As for the tires, I think the preference is to go wide rather than tall...so on a 19x9.5 the popular fitments are 275, 265, and 255...30/19. Some have fit a 285/30/19, but you'll need more offset than +40...around +45 would let you fit a 285/30/19.
Also tire make becomes important as you start to go wider...a rounded sidewall versus a square sidewall.

Front: 19x8.5 +35, 245/35-19
Rear: 19x9.5 +40, ill stick with 255/35/19
Is this setup gonna work without rubbing?
