A complete four-wheel kit for you ND or Fiat 124 – Reduce unsprung weight and rotational mass, increase thermal capacity, improve pedal feel. – The key points to performance brake systems
Combine our 11.750″ or 12.190″ front and rear four-piston kits for a complete four-wheel upgrade and drop 26lbs of unsprung mass! Radial mount systems reduce lateral torsion, or flex, offering improved pedal feel and pad release.
We start with a Wilwood 11.750″ rotor paired with our CAD designed and FEA tested hats that weigh just over 1 lb and are designed with cooling reliefs for great thermal dissipation. Our hats and brackets are CNC to a tolerance of .002″ for true run out and proper alignment. Kits are a direct bolt-on, unlike cheaper kits that require hub rings and alignment shims. But we didn’t stop there. Our kits use radial-mount Dynapro radial-mount systems that reduce lateral torsion, or flex, improving pedal feel and virtually eliminating pad taper. The strength of the DynaPro is a combination of process and design. The process of stress-flow forging re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This produces a part with superior strength compared to machined block billet parts or castings. The FEA generated body design features a radial transition between the piston bores and caliper bridges. This eliminates machined steps and shoulders in this critical strength area and substantially increases the resistance against deflection and body separation under high load. Structural deflection and volume displacement testing have proven the efficiency of this innovative design. A two-piece caliper is stiffer, has fewer failure points, and a 30% increase in pad volume compared to traditional 4 piston lug mount kits.

After extensive CAD modeling and FEA testing, we’ve spec’d our kits with an ultra-stiff and strong 7075 brackets in place of the common 6061 used in other kits to mount the lightweight Wilwood four-piston Powerlite. Precision CNC machined for perfect alignment over the OE rotors that requires no modification to the upright to install. We’ve designed our mounting to shift the caliper to the axle centerline for both performance and aesthetics to match the fronts.

Wheel Fitment: We wanted to offer the best performance in every single category, including wheel fitment. Our 11.75″ kits will clear most current aftermarket 15″ and 17″ wheels. Fitment template is available via email. Proper wheel clearance is the responsibility of the end-user.
