The building started in 85, but there were prototypes/technical crap going on for years before that. Likely the braking system was probably finalized in like 83 or 84.

Regardless of all the other talk, I've NEVER had a problem with my 22 year old brakes. This is even including the fact that many of the parts are stock. I can still lock up my brakes on command. Granted I don't have the best tires, but assuming my system was 100% operational back to stock specifications I don't see there being a problem unless I have a giant tire (assuming that would matter?).

However, I've never tracked my car so I'm not qualified to speak in regards to heat, but from what I understand, the 4 piston/vented rotor combination is way over-engineered (just like everything else on the car).

jgrewe is on a distinguished road
I can speak from experience on the track capabilities of the stock FC brake system with braided lines, Motul fluid, racing pads, and 3" cooling ducts on the front only. The system will pull the 2500lb car down from 150 mph to about 40-60mph twice a lap(Daytona 24hr course) over and over again with no problems and do it for 30 minutes without fading.

I like the look of big brakes too, but I'm only willing to carry what I need on the race car. Beware of unsprung weight!
