For the TT Supra front brake upgrade do I just need to buy a set of 93-98 MK4 calipers/pads ? What all do I need to buy ?

Thanks for the help.

I would make sure the pads have the hardware and anti squeal shims. You will also need rotors, the factory GS rotors will not fit.

You will need supra brakes pads, rotors, calipers and all the hardware for the calipers. Most calipers kits will come with the clips, springs and retaining pins. Once you have all the parts, you will have to cut a little bit of the brake shroud and you're golden. Depending on where you sourced your calipers. I recommend painting them before installing it onto the car. The calipers I bought started looking pretty ugly after 1 year. If you want to use the factory 17 inch rims, you will need a 20mm spacer.
