I like HKS and XS.
I can't wait for them to make parts for the rx-8.
Heck I can't wait for the rx-8.

*cough* .... ummmm....

really, considering a favourite brand for higher power parts is kinda, well, silly in my opinion: we known't yet anything about who will make what, at what cost, with what capabilities, what other bits it'll work with, or what the quality is... buying something because it's got a name on it is not always the best idea.

i would bet with u that there is going to be A LOT of after market parts for RX8

While I agree that there eventually will be a lot of aftermarket parts for the RX-8, it will be quite some time before there are anough 8's in the market, to allow the higher volumes for the percentage that want to mod it, to bring the costs down on mods. Of course, for the right price, ANYTHING can be done, but the more common a part/kit/mod is out there, the cheaper it will be.
