I been talking to a few companies about lightened rotars for our cars. Would they help or hurt? can somone fill me in so I can decide whether this is somthing I wana look further into.

 

^^^^^^

 

it should help like a lighter flywheel or rims allowing the engine to rev quicker. i often thought about that. like an aluminum or magnesium core with chromoly outer. of course designing it for the different expansion rates. what about titanium? a lot of options. i'm curious as to what all mazda has experimented with.

 

Hmmm...interesting. I've never heard or thought about that. My assumption would be what jeremy said. Hmmm...

 

A few companies already make em. Pineapple racing has em. Not sure how much they want for em tho

 

Yes, Pineapple Racing can lighten rotors. What does it cost? Quite some time ago, Rob mentioned to me that he could do them for only a few hundred Dollars per set in volume (say, 10 or so sets at a time). This is significantly less than what Racing Beat charges, to say the least. Mainly, though, it's a racing thing. Usually, there are a lot better ways to invest your money in upgrades. Put the money, instead, into his proprietary oil mods and/or a nice streetport. :-) If you serously want lighter rotors, however, give Rob a call at (503) 233-3878 or shoot him an email at rob@pineappleracing.com .
