They just made all the Motorsport racers sign a new agreement starting today stating that they can't be buying parts for other people so you're probably SOL on the 5.12 gearset unless you manage to find it used somewhere

I take it yours are not for sale diesaldad?

They're shelved for our RX-8 racecar project. At this time I'm not interested in selling them.

still no proof of 13's...........rx8's are slow....its just a fact you learn to live with.....its still very fun to drive and driving feel is hard to replicate......

Now here is mod you can live with and beat that Z in the quarter mile. You can keep your stock engine up front and of course no one would notice the mods you made in the back. Jus tell others "it's a new flow through exhaudt system"!
Another benefit is tailgaters will get toasted.
I think you can use synthetic in the motor in the back. Any additional thoughts on that though, out there???
