I will soon be running the rears (18x8.5 +33) all around on my car with 245/40/18. Hell, you can't beat them for ~18.62 lbs each!!!
Just keep in mind, if you pick up a set, they're staggered; 18x8 +30 front and 18x8.5 +33 rear. I picked up two sets and sold the fronts.
EDIT: Doh! I didn't even look at the picture... I thought you were talking about the V1 Track Model wheels...
Screw those new ones. They're heavy as balls!!!! 21.25 lbs front and 29.50 lbs rear!!!!
V1 Track wheels FTMFW!!!
