Da wheel thread.

[VTSTOMPER]

Hey folks!

I have been looking *drooling* on wheels now for a few days, and I want to end up with something that makes me happy.

I do NOT want a wheel that sticks out (meaning sticks out beyond the flairs. I have found the Helo black's in a 20X10 with a -12mm Offset. Trouble is, I have not a clue what offset I need to be looking for. Any ideas?

Here are the stock sizes...Wheel size 17x8.5
Wheel offset +18mm / 5.5" rear spacing. Do I need to match the offset with aftermarket 20's...and if I go 20, the wheel is 2 inches wider...acks...wtf Let me know what you all did...and toss a pic up.
