Hey, i was wondering if anyone makes lightweight rotors either S4 or S5. i did a search and came up with nothing. Also what do you guys think of them,what are the PRO'S and CON'S of using them? thanks guys

 

check racingbeat.com, it's not worth the price though unless you are going to build some kind of sponsored race car. if you want quicker rev, get a lightened flywheel. for pro's and con's i would have to say the only con would be the price.

 

Now one *makes* lightweight rotors, they merely take existing rotors and lighten them through milling and such. CLR does some crazy work, search for them.

 

i wouldn't mind some of the CLR rotors but i'm afraid to ask how much they want to have a pair milled..

 

thanks guys

 

just wondering outloud but do you guys know if these milled rotors come with new counterweights that have been milled to match? that would seem like a prudent changed to make at the same time...

 

you ship them the complete rotating assembly and they balance everything. not sure if they lighten the counterweights or not though.

 

ah after reading racingbeats description i have answered my own question.

the counterweights are for moral support, the rotors are the ones doing the work and are lightened to aid in higher RPM smooth operation, lightening the counterweights will only help that slightly and a much easier approach would be a lighter flywheel than lighter counterweights.

 

2,100!!!! i think i stick with stock ones

 

uh the counterweights balance the assembly. if you change one part of it the rest of it would need to be changed as well to match.
