Final piece in the puzzle before it gets out on track at Bedford on the 15th, pretty much the ultimate brake set up for the fronts bar a stupidly expensive carbon ceramic disc setup. BTCC spec front brake set up. These are the same calipers used by the current BTCC cars, 6 pot CP9660 and the discs and pads I have are used BTCC items. https://apracing.com/race-car/brake...on-cp9660-2-3s4l-180mm-centres-18mm-thick-pad The top teams only run the discs and pads for one race or practice etc. They get through a huge amount of these so they are available at very knock down prices used. The discs are AP Racing 368 X36 mm that are specifically designed for the BTCC cars as the largest brake they can squeeze under the 18 inch rims they use. The 3 sets of discs I have are all 35.8- 35.9mm thick against 36mm thick when new. Pads have 18mm of friction material when new, second hand pads typically 16-17mm. The discs on the car ATM were on Andrew Jordans car last year. They were redesigned 2 years ago to improve them with heavy duty Bobbins for the floating disc and S shape vanes for cooling, the standard pad is a Raybestos ST45, They are an American company and make lots of stuff for American racing series like Indy Car. I have watched the touring cars racing and have always been impressed by how quick the stop, I now know why. You only have to wave your foot across the brake and the speed starts disappearing. Normal heavy brake pressure application just results in a lock up at what ever speed you care to be doing. Only one real issue fitting these and that was caused by the fact I have MK2 TT bottom ball joints. These allow a lot more camber than standard ball joints. However the knuckle on the bottom ball joint is very close to the disc. Requires some attention with an angle grinder. The complete brake system disc, bell, bobbins, caliper and pads as well as caliper adapters weighs in at 14.9Kg. I weighed a standard 312mm system a few years ago at 13.6Kg. The 6 pot calipers are well matched to the TT with the piston area only being about 10% bigger than the standard calipers. Loads of clearance on my rims. used pads weight of all the parts combined. The bottom ball joint does foul the disc. Needs some attention with an angle grinder. Back side of the disc that picked up a small score from the ball joint. The float is in the discs and not the bell, so the bells don't wear out.
