Hi guys, so I put on the 997.1 gt3rs wheels on my 997.2 c2. I was wondering how much wheel spacing can be added on the rear wheel. Currently it has a 12.0 x 19 Offset 67 wheels with 305/30ZR-19 tires on the rear. And the suspension has been upgraded to Ohlins Rd and Track, and the ride height is the same as a stock gt3.

 

Regular GT3 wheels are 12" with an offset of 68.

I had my custom Forgelines made as 12" wide with an offset of 74, but my car isn't symmetrical (many 997s aren't) and that's as far out as I could go on the one side to not have poke.

Just take a digital caliper and measure how much further out you want the wheel lip and that's the width spacer you'll want.

This is what I consider optimal visual placement.

 

Got it and thank you! Looks great!
