Sorry to dig up an old thread. Just picked up an 05 SC for my son. Has LS400 front calipers and cross drilled rotors. I do not see RCA's though. Where do the LS400 calipers hit or cause clearance issues without RCA's? Wanting to figure that part out before worrying about wheels as the car needs them. The SC I bought has 109K miles but sat for 3-4 years. Brand new coilovers. Also, when looking for wheels, will all 18"s clear the LS400 brakes? Or are there known OEM wheels that will clear and look good on the SC?

Check the calipers to see if previous owners grind it down instead of using RCA.

Where does the calipers hit? Where would they be ground down? Only area I see that looks to be an issue, is the outer tie rod castle nut rests against the caliper. Looks like it had to be clearance there.

For the supra tt calipers, do you need supra tt calipers mounting brackets, or do they fit on the sc430 mounting brackets? Thanks

It's direct bolt on. No adapter needed.

Excellent, thanks! Do you know if the brake pads are the same size? I doubt it but I just put new brake pads and would love to re use them 😂

You need Supra's brake pads. It's bigger than the sc430's pad.

You need Supra's rotors too, just to make sure.
