Hey all, Just thought I would post up some pictures of my new brakes that I put together for the front and rear of the Eclipse!
I put together this brake combination to help with unsprung weight as well as increasing braking capacity in a street/drag strip application. This setup should easily handle street driving, and stop easily from 150+mph at the track without a parachute. These brakes are not meant for road race or autocross use -- I would recommend a beefier brake setup for that. As well, these were designed to easily clear a 16" aftermarket wheel.
The rear is a Wilwood 4-piston Dynapro caliper with a 11.75"x0.81" vented/scalloped/drilled rotors and custom hats/brackets with Wilwood E-Pads and stainless lines. Wilwood fasteners and safety wired.
The front is a Wilwood 4-piston Forged Superlite caliper with 12.2"x0.81" vented/scalloped/drilled rotors, Wilwood hats, modified TCE brackets, with Wilwood E-Pads and stainless lines. Wilwood fasteners and safety wired.
The rear will be getting a hydraulic staging brake instead of the stock E-brake assembly.
The front rotor setup required quite a bit of spindle grinding, modified TCE bracketry, and extended wheel studs to run with this rotor/hat combination. The old combination utilized a 12.2"x0.81 directionally vaned Wilwood GT rotor that had a 8x7.62" bolt pattern and did not require spindle modification. Now it is a 8x7" pattern and really required clearancing with a die grinder and a carbide bit for cutting steel, as well as modification/removal of the OEM wheel speed sensors.
Overall, it should provide a substantial improvement over the stock rear brake setup that was still on the car (with just EBC green pads), while providing a lighter brake package, lowered inertia and reduced unsprung weight.
The rear hubs being used are DSS Stage 5x axles/hubs with ARP studs, and the front are OEM hubs which will be receiving ARP extended wheel studs.
The ABS sensors will be fully removed from all spindles as it simply cannot keep up with the braking capacity of this setup.
The front and rear brake hardware was also safety wired and blue loctite.
I will post up some weight comparison stuff on the rears, as well as a bit more on the aftermarket fronts I was running (12.2"x0.81" Wilwood GT directionally vaned rotors with Coleman custom hats).
The old directionally vaned Wilwood GT rotors were 9.5#, the hats were 2#, and the hardware was another ~1#. The new front rotors weigh 5.5#, the hats are around the same weight and the hardware is around the same. Overall, around a 4.0#-4.5# per front corner reduction in mass by quick estimation. I will get further actual weights when I get a better scale.
The rear brakes are substantially beefier than stock and are lighter than stock by several pounds per corner. The rotors weigh 4.9#. I will get additional weights on the rest of the components soon for comparison.
Here's some pictures of both the front and rear installed on the car (mocked/final fitment). Please ignore the messy garage and the 7-bolt motor!
Enjoy!
