Okay,
I installed two sets of calipers this weekend, one on a Legend car and the other a roadster. The weight savings on both cars was was 7.2lb.s per side or 14.8lbs off the front of the car.
I added 16 lbs of weight to both cars to compensate for pad wear.
I can tell you the shims supplied with both sets were not sufficient to center the caliper upon the rotor. I ended up with .055" on one car and .060" of required spacer one the other.
The next road race is in a couple of weeks and we'll see how they work.
Two things, I recommend when installing;
1) Get longer bolts for the bracket mounting to the caliper, the stock bolts are not long enough.
2) Spend your time getting the caliper centered on the rotor, it will help prolong the brake pad life.
Although I have never spent a dime on BM parts as I do all of my own brake work for myself and many, many others, if this package works as well as anything on the current market at the time of introduction, then they can only get better and make you faster.
I will pass along the information as I get it. I hope to have a circle track Legend on the package in the next couple of weeks.
