I reaad somewhere that the 911 GT2 has ultra-lightweight ceramic rotors...Has anyone ever come across a ceramic rotor kit for a FD? I was just wondering how I could get better braking than stock, as well as saving a few lbs. of unsprung weight...

thanks,

Ceramic and carbon brakes are really, really expensive and I don't know of any kits for the RX-7.

You can get better braking for the same weight as stock with one the AP 13" 4-piston kits from N-Tech or M2.

Unless you're doing track racing events, the stock brakes are plenty adequate for normal road driving!

 

All one would have to do is aquire the ceramic 911TT parts, and have caliper mounts, and perhaps new rotor hats machined just like they do for the standard Porsche big red kits. I doub't its significantly different, in fact the Mov-It parts might even work for the ceramic rotors.

Thats a big "All" though. Its, i believe, a $6000-9000 dollar option on the TT, so buying parts seperately would be more, plus fabbing any adapters need. Brakes might end up worth more than the rest of the car.

 

thanks for the replies guys, and the main reason i was thinking of the ceramic rotors was for weight. I was just trying to think of ways to improve braking while saving as much weight as possible.

another question: how much weight does slotting/x-drilling save? (is it noticable?)

 

I doubt its very noticeable. X-drilling your non-X-drilled rotors is BAD. Just get some slotted rottors and youll be fine.

 

my dad just put ceramic brakes on his navigator. mroe expensive than usual brake compnents (i dotn remember whether they are ceramic pads or rotors...maybe both) but it made quite a difference

 

Probably just pads unless he spent many thousands of dollars on it. I believe there are a fair number of brake pads with ceramic content.

Also, we've pretty much been using carbon and ceramic interchangably here (me included), but they are not the same thing. Perhaps some setups use both materials, but I think the Porsche brake options are carbon/carbon (rotor/pad). There are also a lot of MMC (metal matrix composite) brake parts used on lighter vehicles (bikes and carts) but they don't fare as well on cars, and I don't even know if these classify as "ceramic". The Sport Compact Car Project RX-7 had some MMC rotors on it that seemed to work well initially, but ended up failing (if I remember correctly).

Plymouth Prowler uses the MMC discs, I believe. I think they are aluminum based with carbon strand reinforcement.
