These are being offered to racers in response to so many paying $800.00 plus for front brakes from others. Remember, the caliper on these cars is from a 79 celica, it will not be available forever as is. I think you will spend $350 or so and compete or be better than those with the existing aftermarket stuff. To me more importantly, maintainingthis syatem will be ALOT cheaper than the current. You can still choose to run your current stuff, the new stuff will be as good as the aftermarket stuff, just cheaper. So if you like what you hAVE KEEP IT!
