Well - I don't expect to sell millions - but..
It should come in a little less than the TWR kit - I expect the much higher cost of 2 piece rotors to them was an issue - but I dunno.
There are quite a few Brembo rear kits out there on R160 cars - they will need rotors at some point.
There are more than a few totalled STi's and nothing goes to waste - doing a R180 swap is pretty pricey/painful if you are just doing it to put the Brembo's on.
I would hope to sell a few matching front rotors to go along w/ it as well.
It's not the kind of thing TireRack would push for - but it may benefit my 2 bit operation - ande DBA has had requests for this before. They are certainly specifically interested in being strong in the Subaru market as they have always been.
We shall see I suppose.
The 2 pot rear setup still requires adaptors - and new rotors - it ain't exactly cheap to put those on a WRX.
