Hi Guys, Stewart at FreakyParts.
Spotted this post and thought I'd answer a few of the questions.
The 316mm kit comes with a pair do 316x28mm cast rotors. The cost for replacements is around £125.00 plus shipping, but you can source locally if you like. They're the same discs found on the Mercedes C36 AMG MY94-98. They just need the PCD redrilling to 4x114.3. Any local machine shop can do this for a small charge.
The 2 piece 309x32mm kit comes with a pair of Wilwood 160-5843/4 UL Straight vained rotors. These are around £75.00 each for replacements.
We also offer an upgrade to the HD (high carbon content) rotors for ultimate performance for an extra £100.00 on top of the kit. Replacement rotors for this kit are around £125.00 each.
Both are a direct bolt on kit for the early Evo, and don't need new wheels buying to change the PCD to 5 stud.
The kits will fit behind most 16" Motorsport wheels and most 17" road wheels.
We've stayed away from adapting the later Brembos to fit the car as it requires machining the calipers. In our view this is not ideal as if this fails, we'll be liable. We'd rather supply a tried and tested kit which fits rather than bodging something to make it fit.
If you have your heart set on Brembos, we also do the big red Brembo (style) upgrade. This uses new Porsche radial mount calipers, but are un-branded (due to licencing restrictions). These are beasts and can be made to fit any disc you want. We package it with a set of 316x28mm but if you have something specific, we design our kits in-house so can make something to suit your requirements.
