I have a couple of questions that i can't get answered from searching.

1) If i am currently running RCAs, do i still need to shave the caliper and tie rod bolt?

2) What is the smallest size rim that i can run? Will my stock 16s fit?

3) Do these brakes require wheel spacers to prevent running issues?

Thanks

1) I am under the impression that RCAs will give you the clearance to run a 4-piston brake upgrade like the LS or Supra brake kits.

2) Every site that I've ever viewed had a statement like this with regards to wheel size and moving from a 2 piston to 4 piston (or larger) big brake kit.

"Big brake replacement or upgrade for your Toyota Supra,Lexus GS300,400,430 or SC300,400 Kit includes new 4-piston calipers,shim kit,brake pads,rotors and SS lines Hi-pad/disc offset is needed to accomodate larger calipers, will not work with stock wheels ( Except Supra TT )"

My suggestion would be to measure the inside diameter of your existing wheels and use that gauge to understand how much extra room you have. My presumption is that you will need at least 17 inch wheels.

3) No, unless you're using stock 16's then you will most likely need spacers.

IMO if you're using stock 16's your best bet for a brake upgrade would be stainless steel brake lines, upgraded rotors, and upgraded pads. There are lots of great kits put together for you like by Rotora or StopTech that are designed to be used with stockies.
