Wow been a while since last update.
So here goes
Not the best pics but
Installed an Oil Cooler
Shorter belt for aircon removal
Aircon be gone
Oil cooler take off plate im running a remote thermostat.
Bigger brakes 312mm audi TT discs stock calipers. Stops like it should now.
pictures testing on a mates st202
Tested on track and with stock setup i managed 1 lap of silverstone race circuit before no brakes on this setup i had zero fade after 5 laps.
Stock calipers are fitted to new brackets design below.
Just need spacers for studs. and HT bolts.
Found the caliper mount PCD which is 85mm
Stock disc is 277mm and new 312mm so bit of maths and thats
35mm bigger / 2 and thats 17.5mm
So add 17.5 mm to 85mm and new caliper pcd will be 102.5mm
Caliper holes are 130mm apart so a bracket like this is required.
2 Holes will be 12mm and 2 will be m12 x 1.25 threaded.
rotor hat height is 9mm different ( in theory ) so i need a 10mm plate and 1mm spacer behind disk or 8mm plate and 1mm shims on caliper.
4 x m12 HT bolts also needed. grade 8.8 will do but trying to get some grade 12.9 button cap bolts.
You need some shims also for studs but thats just 12mm id and 15mm od stainless tube so disc is central on hub.
