I’ve been using the T3 micro front brakes on a 510 strut over 1.5 years now. It uses a 280zx rotor with a custom spacer/adapter for the hub mount and the Dynalite caliper with an adapter to the strut. It fits over my 13” wheels which is why I selected their kit. It’s straightforward to install and included all the hardware and lines. I also installed a new 7/8” BMC at the same time.
I didn’t do any comparative testing but I’ve been satisfied with my braking and feels significantly improved over my previous stock plus setup.
Troy’s and DP racing’s use custom rotor and hat which an argument against the T3 kit.
