Exploited these discs for 5 years on the Peugeot 307, during this period did not reveal any shortcomings. They perfectly resist our "favorite" roads, more than once fell into the pits, while the disks were not damaged and were perfectly balanced. The paintwork, even after 5 years, remained in excellent condition (I highly recommend that you follow the tire fitters when balancing, it is necessary to install self-adhesive weights on the alloy wheels, and not as they do by putting stuffed weights at the back, thereby damaging the paintwork, and aluminum is very susceptible to oxidation and oxidizes over time entire disk).
