Default 18in Rim upgrade question
I have a 99 C2 coupe.
I'm upgrading stock 17 inch rims for BBS sport classic 18in rims.
Anyone know the correct offsets for the

18 x 8
18 x 10

Porsche owners manual shows the 18s as

18 x 7.5 with 50mm offset
18 x 10 with a 65mm offset

Found a set of BBS on ebay with the follwing specs

18x 8 52 mm offset
18x 10 65mm offset.

Is the offset correct for the front rims?

Thanks!

Yes, those are RoW offsets and will work just fine.

Is it possible to run an 18x11 in the back? I think this is what the GT3 uses. Is there any reason why this wouldn't work on a C4?

Front: (18 x 8) (Offset +50)
Rear: (18 x 11) (Offest +45)

The rear of 11" will work but not at that offset. Those are widebody offsets. The narrow body offset on the 11" is 63 if I am not mistaken (ala GT3).

Thank you Dell. After checking the GT3 forum, that looks right. BTW,thanks for the ML brake info, it went without a hitch.
