The TRD brake setup is FOR SALE! $350 OBO Located in the SF Bay Area. Another $40 to ship them 2-3 day USPS Priority anywhere in U.S.
These are built from new/reman FC RX-7 4-piston aluminum calipers. There is a full write up on 3tcgarage forum. These work great and will take tons more abuse than the factory solid discs and single piston iron caliper.
I had to swap them out for a set of floating (non-opposing) C4 Corvette calipers for better clearance to the new JNC wheels. These did fit a set of XXR 002's 15 x 8, 0mm offset. The sale includes two sets of Hawk pads (HPS and 5.0's), and another set of ceramics - all at about 80% left, TRD calipers and custom caliper brackets. To complete the swap you will need to machine the rotor-hub adapter plates (pic below), and buy a pair of 1984 300ZX non-turbo rotors.
The forum is not allowing me to upload photos. I have them posted on 3tc garage writeup.
