ADVEVO,
I have been speaking to Alcon regarding EVO brake kits, they don't make one at the momment, but are willing to. The basic spec would be a full floating (bobin?) 355mm (The chap I spoke with said he thinks this is the max size they can get under 17in wheels) disc with monobloc 6 pot calipers with dust seals. This as you say is the WRC spec setup (appart from maybe disc size) I expect they would be able to do 365-375mm for the 18in wheels bod's.
I will also ask them about doing a 4pot caliper set up for the back and maybe larger discs.
Price I ain't sure of at the mo. Won't be cheap but will be superior to AP and hopefully un-warpable. They will be a full on, noisey in use at low speeds, etc, etc. Track day boys should luv um though.
Why you may ask I am bothering to do this. I have eaten 2 sets of discs and pads in 3 months. hmmm. It is starting to get expensive, and I am getting chessed off!
I will update when funds and time allow me to start looking at this more closely, If you are interested in progressing this yourself, then I can supply contact details at ALCON.
Cheers,
