I am looking to add a set of front and rear Brembos that come on the track model when I get my Roadster. My question is when I add them can I use the stock rotor w/ the OEM Brembos until I buy the OEM rotors for the Track model? (I won't be tracking my car just drive normal and for show!) Any input would be appreciated!

 

No you can't due to differance in required size.

I have DBA rotors for sale BTW.

some very nice 2-piece rotors for the Brembos

 

Are you just planning to buy the calipers? Because if you buy the kit, it'll come with the rotors. Also, you save a lot if you buy used. Some members sell their track brembos. You can sometimes find them on the private classifieds.
