Default Possible oem BBK option.

I have had terrible luck trying to find TT rear calipers for any reasonable price so i went looking for some other options and i may have found something. The cadillac ATS has Brembo 4 piston fronts and 2 pistons rears that appear to be nearly the exact same size as the Supra TTs.

Fronts :
Supra TT -
diameter = 323mm
nom thickness = 30mm

ATS:
diameter = 321mm
nom thickness = 30mm

Rear:

Supra TT:
diameter = 324mm
nom thickness = 16mm(not certain on this one)

ATS:
diameter = 324mm
nom thickness = ?? not sure either, but i assume they would be pretty close too the supras.

Going by these numbers, we should be able to use the ATS brembos on our cars with the TT rotors and possibly pads as well, the only thing required would presumably be a custom mounting bracket and brake lines. Another bonus would be that these calipers look pretty good, and being that they're from a GM vehicle they're pretty cheap, i've seen them go on ebay for around $400-500 for a full set.

I have ATS-V 4 pot rears on my 96 SC300 paired with ISF rotors. You will need a custom bracket. There is an old member on here who made them.
Mine might be up for sale soon, putting it back to stock for sale.

Are those the 320mm or the 355mm calipers?

hi, did this ever pan out? Were you trying to install on the SC300/400 or SC430? Would really like to hear your results or any info you found out.

Personally, I bought the Jeep kit, and I'm going to have monster calipers and rotors as they are using all isf rotors and jeep SRT8 calipers.

Are you making the brackets yourself?
