21” wheels?

[yinzer]

absolutely not
different bolt pattern and wildly higher offsets

can you fit 21s
yes

is it worth it?
100% no on anything close to factory car

maybe if you had a full aero setup on a show car

otherwise you're running rubber bands and will still have a gap

I may have to agree, the little research I’ve done so far would have the rear 21” running a 25 series sidewall. Too thin for me. I’ll check a little bit more just to be sure. Thanks.

I wouldn’t do it but my 19”s look really small almost like 17’s in person. The Z has such wide hips , I’m probably going up to 20” wheels. My C8 has 20’s fr. & 21’s rear a 305/30/21. Not sure how performance and handling on the z with 20/21’s just do a 20”staggered setup.
