Are they really? Hmmm..... Wonder why this one is sitting on the underside of the car then and wasn't when I just had the KA in it. I was thinking that maybe the SR downpipes were a bit longer.
AE92blackout, I'd love to get rid of these rims but I'd need another set... Keep inmind these tires have less than 500miles on them.
