doesn't a company or two already make this?
So essentially you'd have to do it cheaper.
TWR's kit is $649 for adapters and 2x 2-piece rotors.
In fact i've also heard the rotors in question can be had from Brembo already. They make a kit with calipers, adapters, and rotors, all setup for the R160 driveline.
I believe basically the calipers are identical to the STi Brembo rears (they even come in gold). Unfortunately the price on this kit is $1400 or so.
If only someone could get pricing from them to sell their adapters and rotors without the calipers? or perhaps just the rotor, and produce the adapter?
just a couple ideas for ya. not puttin ya down or anything. I am definately interested in a bolt-on Brembo setup.
I already run 4-pot/2pots on my WRX, all bolt-on. (I have some of the original japanese-market 2pot rear adapters)
