Most of us are running the Reyland AP Racing Kit.
I had mine for 2 years now on my TD Turbo car and had zero issues with them.
Been running the car on track with zero fade.
APRacing (Cosworth Spec) 6pot/355mm floating fronts and matching APRacing 4pot/335mm rears. They cost £4300 from partbox but I was quite lucky that they were doing 20% discount at the time so got them for £3500.
