I want to upgrade my manual drums in the front to power discs in the front. Any suggestions? Iv'e looked at SSBC, Baer, MP......Is the SSBC Force 10 with 13" rotors worth the $$$$. I doubt you can notice the difference between 11" and 13" rotors unless you race on the track which I don't. Also if I go with the 13's then I have to get 17" wheels which is not a big deal since I'm getting new wheels anyway. Any feedback appreciated.
