I like my Wilwood based system better. 
But they were about that much. (The rear brake uses the stock parking brake system, so the rear brakes were more than the front ones.)
ARz's setup is the best deal around for what you get.
Front brakes. GNIII 6 piston calipers, 14"x1.38" slotted and spirally vented rotors on aluminum hats.
Rear brakes. Billet Dynalite 4 piston calipers, 14"x1.25" slotted and spirally vented rotors on a steel custom hat that acts as the parking brake drum, just like stock.
Result is zero brake fade, even after repeated stops from 140mph, and they seem to just get better as they heat up actually. The brakes were custom built by Precision Brakes out of Portland. I would not do business with them again however, as they were NO help whatsoever when I had an issue with the zinc coating on the rotors. (Made them pulse with use.) The brake lines they provided were pretty shitty too. Not impressive for what I spent on this at all. I plan on trying out Hawk pads when these Wilwood ones wear out. (Not going to be for a very long time it appears.)
Main thing that Precision did right was get the brake bias right from the start. For that I praise them. No bias valve needed, however, they did include one in the setup, but I see no reason to use it as the brakes work perfectly with the stock ABS. If anything, there is slighlty more rear brake bias than before, and IMHO, the Supra was too biased to the front stock, so this is an improvement. (Besides, if the rear brakes lock up, the ABS kicks in, and halts any skid, so you WANT the rears to be on the verge of skid, and modulated by the ABS computer while your foot modulates the front brakes up to the point where ABS kicks in there, and you avoid loss of control by locking up any wheels...) The car just flat out stops when you hit the brakes, and that's what I wanted.

Adjuster, my stock brakes work better than yours.....because my car actually
runs.
Those are nice brakes, but I'd go with Andy's set first.
