WTF that expensive and that heavy? I thought they would weigh like 7lbs or something. lol. For that weight I would get some 5zigen wheels that look like those work wheels if I wanted that look bad enough.
The RPF1s are used on some of the fastest cars in motorsports. If they are good enough for those cars they should be more then strong enough for my little bolt-on SE-R. I havent heard of the RPFs breaking from racing unless there was an accident. They arent Rotas. lol
