Getting ready to pull the trigger on a new custom set of forged wheels for my pp gt with brembos. The question is, with any width/offset I want... What will give me the optimal fitment, concavity while still clearing the brembos in front. I have coils so height/ camber adjustment is easy. I'm thinking something in the range of 20 inch 9.5/10.5 et 22/30? Examples would be great!!! Thanks

Good evening and great question. Allow us to shine some light on the fitment question considering we have had experiences with many different brands and setups.

Having fitted so many and catering to each client wish list which normally including spacer because the wheels just did not sit flush enough or were not wide enough to accommodate some of the tires sizes enthusiasts wanted to use. We have pinpointed the size and offset that fits perfectly without any rubbing and provides the width as well. That being the 20x10/20x11 setup in the 35/50mm offsets. If you would like to go a little narrower but still have that flush look, we can adjust the offsets on a custom setup to still place the wheels in the same position as our fitment.

For examples of the 20x10/20x11 fitment, please feel free to take a look at these examples on our gallery section.

I know the vendors here can give you a much better idea/info than I can, but I'm running 20x10's all around with a +40 offset. My front tires are 275/35's, my rears are 295/35's, lowered on an Eibach pro-kit and no issues anywhere with rubbing. I have the PP as well. But as Grintch said, some wider wheels would look BAD A**!!!

If you're going custom, why not take advantage and run a wider wheel than the typical off the shelf solutions? Something like 11" F / 12" R.
I considered that for the performance and grip benefits, but the particular wheels I'm looking at get a much better concave (as most wheels do) with a lower offset. That is my thought with the 9.5/10.5... That balance between performance and concavity

Thanks that's very close to my measurements. Do you think that will poke in front too much?
For tire size, I'm not totally sure yet. Definitely looking for recommendations as I don't want to stretch at all really but definetly wanting to avoid going to large and having rubbing issues.

No poke itll be dead flush

Tire size wise

255/35/20 or 275/35/20 & 295/35/20 or 295/30/20

Rohana rf2 in matte black, i remember the first setup I did haha. Called the guys at rohana they didnt think it would fit. Come to find out it was the worlds first s550 on that combo setup. Came out super sweet and did 315 rears.

Offset is a consequence here, not a cause.

Narrower wheels have to have a lower +offset in order to make the concave appearance even happen. A wider wheel with the same front-side spacing would have the same amount of 'concave', but with all of the additional width being added to the backspacing you end up with a larger +offset number as a consequence.

I have 10.5 ET 25 with 275/35/20 no poke in front but they are stretched slightly. I could run a 285/30/20 in front but might rub in the rear as my Rear wheels poke about 5mm.
