I purchased a set from 'trinet' motorsports; $200 for all four corners.
The rotors fit well, and I was pleased with them, but the fronts started to hot spot after a panic stop. They were resurfaced, but the person who did the resurfacing referred to the metal used as 'soft', and said it was likely they would hot spot again.
Prior to these trinet brakes I purchased the full set of 4 rotors from dali racing, along with axxiss ultimate pads, stainless lines, and ATE blue - in under a year the rotors were shot, while the pads had about 50% wear remaining. I had never before this gone through rotors faster than pads.
My advice would be to either stick to a brand name (eg brembo or powerslot), or just purchase OEM blanks.
