I'm pretty much looking for cheap *light* 17x7.5" rims, so I can use 225/45-17 Falken Azenis for autocross.

After going thru a few sets of these tires in the future, they would have payed for themselves, since I'm not burning up my more expensive 225/40-18 ES100s. I wouldn't have to worry about messing up my street tires, and I'll get mor grip on the track while saving money
