Has anyone looked into really light racing wheels. I know the TE37s are about 17 for a 18X9.5, but is there anything lighter? I had a chance to pick up a wheel and tire off of an F-1, and damn are they light! Just curious if BBS (or anybody) makes a wheel like that for the dawg. The wheels I have now are 21lb for a 18X10, but I want lighter! What does a wheel off of a 360 modena weigh? I am sure they will not fit, but curiousity is killing me.
