In Reply to: wheel ratings? posted by john on January 04, 2000 at 23:40:56:
Finding specs on wheels is difficult, as I just got done doing the same thing. I found that the RD Sport wheels were much heavier than they look, as are the majority of aftermarkets. Wheels I found to be light were the BBS RC's (and probably all of the BBS wheels), SSR's, IFG's, Fiskes, ASC Type III, (and the countour replicas were in between at @ 22 lbs). The IFG's, I found, were almost twice as strong as the OEM BMW wheels, weighed 17.5 lbs each, and kept brakes around 100 degrees cooler at the track than the OEM M3 wheels. I finally found a used set and bought them immediately. Fiskes are nice, but too busy and hard to clean for me. SSR's are a good value, but stick out too far, and the ACS Type III's are nice, but too $$$ for me. Hope this helps.
: While looking for a new set of wheels, I have been trying to evaluate what's on the market by more than their appearance. However, I've been discouraged by how hard it is to find out how much a wheel weighs, my assumption being, holding everything else equal, that a lighter wheel is better. Likewise, I can't find any ratings for other aspects of a wheel, such as torsional rigidity, shear factor, and so on. Is this hopeless or is there some way to evaluate the technical performance of wheels?
: More specifically, is there anyone out there who has been racing BMW's and knows which wheels provide the best trade-off between lightness and durability?
