quote:It may be the Wilewood calipers are the best rear solution. Let me just say that I don't like the overall sizing of the fasteners and am concerned that the "adapters" for the calipers are going to be the weak link, or more concerning, the "fuse able link". Especially with the additional torsional stresses applied to them with this level of braking. Particularly in the front.
If you are interested in doing Wilwood calipers on a stock rotor, we can supply you with 2 Wilwood 4 Piston Calipers, 4 Grade 12.9 steel Bolts for mounting the bracket, and 4 Grade 8 steel bolts for mounting the caliper.
You don't have to worry about the bracket being the weakest link. It is made out of 1/2 Steel and the stresses are not perpendicular to the bracket. The stresses are in the same direction as the rotor. I agree, the weakest point would be the smaller mounting bolts that the Pantera has on a stock upright. That's why we upgraded to the 12.9 strength bolt.
