Quick question for all with a 2-piece 362mm setup. I've got the Vagbremtechnik/AP 2-piece kit on my S3, the discs are shot now so I'm looking to replace. Reyland make a rotor to replace the AP ones, they are significantly cheaper. I've spoken to Reyland who have told me that the downsides to there disc are essentially just the weight & that the internal veins are straight rather than curved. They said that for a fast road car with only a few track visits a year I would notice no difference between the Reyland & AP units. Has anybody had track experience with these discs vs the AP ones? Am I going to be kicking myself when I come off the ring with warped rotors or are these really just as good as the AP ones?
