Arite chaps, I fancy some new wheels for my 3door Cosworth, ive trimmed the rear archs back and was wanting to know the best offset for wheels, ive been looking at some with Et37, would these sit to far in the arch? I dont want it to look like a American muscle car

 

Et37 is standard 3 door fitment mate

 

Mine are et35 from memory on my 18s

 

The standard wheels sit in the archs abit though dont they

Did you trim the archs for the 18's?

 

ive been thinking about this myself .i was wondering if i just kept a 15 inch wheel is it possible to have big enough offset to let wheels out flush with outside of arch with the use of coilovers for to stop so much travel and prevent wheels catching arches

 

Yes mate, arches were indeed trimmed
