Will this size fit my 01 is300 all around without having to fender roll? Also will it fit flush with my fender? Or for just inside or outside of it?

 

Mmmhhh. Sorry, this is a too sensible topic for me. Because wheel size requires specific knowledges that I doesn't have.

But I remember, as I was searching mine, that my tuning boutique around the street, was very knowledgeable in terms of knowing how the wheels would fit on the end product. I remember to have chosen a version that is only half an inch wider as the original wheels. And they fit perfectly without fender rolling. 8.75 could pose some problems depending of the amount of concavity those wheels have.

Maybe it could be an idea to go visit a pro and spend 80 $ more for a valuable service. Don't know if this brand is sold in shops around you, but I would take a guess that you could find nearly everything for cars around washington.

 

For a nice flush look, without looking ricer or requiring rolled fenders, you need to be in the 8" +40 zone. I have 8.5" +45 and they look nice and flush without being ricer, but my fenders have been rolled.

An 8.75" +35 will stick out about 15mm more than an 8" +40

So, judge from that if you think it'll fit.
