Since most of the gtr experienced the disc brake cracking issues..we here at ATS Automobile...Recently installed the performance friction disc to one of the gtr. Since most of the GTR owner prefer the AP Racing disc..we give it a try by using this brand to figure out how the braking results for this high speed machine. The result was amazing. This discs are the floating type of disc and really perform miracle especially at high speed + high temperature level. In term of pricing ..this discs will cost more compared to the AP racing.
