quick question about offset on S13...

[srpwrd]

Okay, I know nothing about offset's when it comes to wheels. I am looking at a set right now for my '91 240sx fastback, am wanting it flush with the wheelwell, can anyone please help me and find out how these rims would look on my car:

18x8.5 +30 Offset front
18x9.5 +40 Offest rear

thanks in advance!

if you can afford those wheels, you can afford for your fenders to be rolled and slightly pulled... I'd say go
18*8.5 +30 front (same)
18*9.5 +30 rear

if you want to run these w/o rolling, you may need to go slightly higher offset, or run more nega camb. To tuck the fronts you'll probably be running around -3 deg anyway... and rears, I suspect you'll need a similar amount.
Have fun!
