After seeing a number of brake upgrades on AF where vented discs are used with heavy sliding calipers, I thought I would share this experience with those thinking of spending a lot of time and money on such an upgrade.
I chose to save some money, time and unsprung weight by staying with a basically standard setup. I only upgraded to new discs and a pair of new Mecaparts alloy calipers, no rear limiter and an A110 master cylinder. I removed the backing plate and added ducting to keep it cool.
Although I was sure they would be more than enough on the road with my 1600 R8G, I was not sure if they would cut it on the track. Well last Friday at the Racespec Renault Track Day at SMSP I found they worked fine. I could brake as late or later than most of the late model cars with big brakes and ABS. The light weight Gordini plus the much lower flywheel effect from my brake setup worked fine, no brake fade at the end of the sessions after heaps of heavy late braking.
