What MVP says about these rotors:
DBA (Disc Brakes Australia) makes the highest quality rotors on the market for direct OEM replacement.  These are an easy bolt-on replacement for anyone running the USA-spec 2-piston rear Supra TT calipers. Made in Australia, these are our favorite rotors we have due to their high quality first-run (non-recylced) metal used in the manufacturing process.  You will get longer life out of these than the other options.

NOTE: If you are a non-USA-spec Supra TT and you have not upgraded your calipers then you have what we refer as J-Spec calipers.  In this case you are the same as a USA-spec Non-Turbo Supra and you have the smaller 1-piston rear calipers and you need to shop in the Non-Turbo Supra section for your brake rotors and pads.

Price is per rotor.

What DBA says about these rotors:
Take full advantage of your stoppers with DBA Club Spec 4000 T3 brake rotors. These rotors are full of features desired by the track enthusiast and weekend cruiser alike. DBA's exclusive XG150 high-carbon alloyed iron and TSP process allows each rotor to withstand extreme heat without the serious degradation found in other, lesser rotors. DBA's patented Kangaroo Paw ventilation provides awesome heat dissipation, and their T3 slot design dampens vibration for quiet, responsive braking and pedal feel. To keep these rotors looking as great as they perform, DBA applies a protective paint onto the non-friction areas, along with heat paint marks, so you can monitor peak breaking temperatures. Reign in all of that speed safely with DBA Club Spec 4000 T3 brake rotors.
