So my '95 Z28 convertible is in pieces in my garage right now, getting ready for spring.

One of the projects is a wheel/tire upgrade.

I've been researching and know what I want, but have one final question.

No one seems to list the offsets of the wheels they've installed.

A common upgrade seems to be going to a 17X8.5 with 245/40ZR17 in the front, and a 17X9.5 with 275/40ZR17 in the back.

For the guys running those sizes, what offsets do those wheels have?


Thanks!

And because we all like pics, a flashback to last September.

 

18x8.5 front with 245/40x18 & 18x9.5 with 275/35x18 rears. 56MM offset front & rear. Rear wheels needed a touch from a dremel due to the center bore being about 1.5mm undersized. That took all of 5 minutes per wheel.

 

275x40 is taller than 245x40 so you will want to go taller on the front or shorter on the back. ^^^ has shorter on the back.
