There is another vendor on this site that carries them and lists them on their site, all the available sizes, choices, etc, with prices...I didn't say anything at first because you posted this is the ATS section. Anyways, since they mentioned to contact another company anyways, I'll link you to the Precision Brakes Co product.
The Precision Kits are the 2nd one down (Front) and 3rd one down (Rear)
Big Brake Kits for the Toyota MR2
