That's the setup that Total Performance used to supply. I used them for a year before I installed single puck Wilwoods - and the car finally was able to stop without a few prayers, the e-brake and an anchor. Yes, I know others have used that setup (kinda) successfully, but it is barely marginal at best. I also added a dual chamber master cylinder as well as the required 2 and 10 pound residual valves - regardless of what Total's Mickey Lauria said - and we did argue that several times. Total ended up going to the exact arrangement that I used tho their new calipers didn't have a Wilwood name on them

The 175 Airheart's are set up with a .250 rotor, the Wilwoods, a .375. The brake pad area is about 2x the Airheart's. My recommendation - do yourself a favor and spend some time with a better brake system - with a 'bucket, you need all the edge on safety you can find.
