After looking around for several weeks for a good 2-piece OEM+ setup for my MK6 Golf R and finding options for only low end, non-serviceable 2-piece rotors or overkill "street cred" BBK kits (usually for fronts only) I stumbled on these fully serviceable 2-piece discs from Ceika. I liked that they also do full custom kits for front AND rear unlike most BBK vendors who tell you all you need is fronts, ignoring proper bias and balance. Eventually will be looking at those but right now budget had to be trimmed due to other upgrades and repairs and these fit the bill perfectly.
I have 2 track weekends on these so far and have performed amazingly. The fronts give massive weight savings at 6lb less each, the rears less at only 2.5lbs each. I decided to try EBC yellow pads as an experiment and on any straights these rotors cool down so well they actually bring the Yellows out of the track grip and back to the street grip. This is unfortunate but an issue with the pads not the rotors. I plan to switch to full G-Loc pads and can't wait to take full advantage of the rotors.
Very happy with the product and the customer service was great too, there was a delay in shipping due to supply chain issues and they were easy to reach, very communicative and helpful.
