These wheels really are the best bang for the buck. My 18's weigh roughly 18.5 lbs. Last year, I had them polished as can sort of be seen in my signature. The RPO-2's, I think, were made exclusively for Discount Tire Direct. The RPO-1's were still lighter and built more for the Japanese muscle cars. The 18's I have on my car now are the second set I've purchased. The original set was a staggered set 17/18 (ala SMZ setup). Unfortunately, I sold the original set to a friend who also owns a pearl white 300ZX TT. Good luck.
