Can someone who actually has aftermarket wheels on their GTO tell me the correct offset to get?

I saw the sticky in the wheels forum but there's such a wide margin of offsets I'm not sure what would work FOR SURE. I've seen some atrocious setups on GTOs with ppl that thought they had the right offset.

Not really wanting my wheels to stick out past the fender and shit...

40-35mm's for the front.

For the rear it just depneds on how big of a tire you want to go with. Personally for the rear you need a 40+mm. Now if you are wanting to go with a 255-275 tire on the rear you'll want to get a 45+mm. I really think the best offset with a big tire for the rear would be 50-52mm with a 9.5" wide rim.

For my new wheels I'm going with a 18x8.5 w/38mm front and 18x9.5 w/48mm rear (I wanted 50mm for the rear but we couldn't mill that much off).

Okay, so for the rear, I want a bigger offset to suck the wheel in closer to the car, correct?
