I am getting the ASM +25mm front and rear fender.
planning to run 275 in the rear.... 235 in the front

which width of wheel for 17" would be the best?
and most importantly ... what's the offset for the wheel ( with the +25mm fenders) ?

Thanks in advance

You don't need to buy fender flares to run 275's in the rear..................just wheels with the right / correct offset...........

Not so sure about the 235's for the front.....? Why this size...?

I would ask you what your goal is?

A. put fender flares on the "S" because you like the look.....or....
B. you just want to run wider tires.........

Understanding what you are trying to accomplish will be a factor in what wheel / tire / offset you should choose.

ASM did the fenders to their car... only with 245 all around... I want to do the same thing... except i want to keep the staggered set-up.. therefore the 275 rear 235 front..

probably, put on the Toyo RA-1s.. and 235 is the only size they come in for 17" that's in that range...

My goal is for the look, yet still want the best performance out of it...
just want to know what's the right size of wheel and offset i should go, with the extra 25mm ..

If you're set on 235 front & 275 rear

The correct wheel widths would be:

8.5" - front

10" - rear

As far as offsets go.........you'ld have to do the math.......but here is an educated guess

25.4 mm = 1"..............your fender flares are 25 mm...........so do the deductions from that.

8.5"..........with correct fitment for the front would have approx +56 / +57 offset without the fender flares...........so -25 mm or so to account for the flares..........+33 to +37 might be a safe bet

10" in the rear with correct fitment (no fender flares) would be a +75..............so deducting 25 mm or so would approx +50 to +54 or so.

Just a guess.............but as I mentioned above you can run wider tires without the flares

I'm lowered 1" and running:

225/40/18 in the front - no fender flares needed.........+51 on a 8.0" wheel.

285/30/18 in the rear - no fender flares needed...........+76 on a 10" wheel.

wow... that's a very aggressive offset... you are not having any rubbing issue with this setup?
