Will 18x9 et20 fit stock arches?

Ta for confirming. Pity really, there are a lot more options in lower offsets.

255's up front is getting on for being fairly wide on a street FD isn't it?

I'm no expert on car dynamics but my friends and I feel the car rotates far better with the fronts two steps smaller than the rears. Just my 2p on square set ups

I wouldn’t worry about a square setup, the stock FD comes with a wider rear tyre compared to the front out the factory.

So i have this Excel spread sheet (I copied it from rx7club.com) that calculates rim to arch & suspension clearances. You can vary the diameter, width, offset



It also calculates the overall rolling diameter of different width v profile combinations. Good to keep an eye on if you want the speedo reading true.



Just can’t figure how to attach it of even if admins would be happy for me to share it. But here a screen shotView attachment 5987

Thnaks for posting this, it will prove very handy going forward

Sorry. I should have been clearer. I meant square tyre wall. I don't want any stretch.

There's a website called willtheyfit

I have 17x9.5 et30 and the offsets are a little much, at 35 would be much more comfortable on a 255

I have 255s all round handles great really sticks to the road

This is incredible information, sticky deserving? Does the actual excel file allow you to play with different offsets and recalculate the clearances? Can anyone confirm its accurate? The clearance calculations either inside and outside are very important.

I'm trying to work out potential new wheel specs and it's a minefield. You look at so many things others have done but add variables like wheel spacers and even the different shape of a sidewall on one tyre over another makes a difference...

Very Cool
Just to confirm this is stock body with or without rolled arches? Im stuck in the decision of whether to roll or not.
