A series of tests conducted in independent laboratories have confirmed the excellent performance of the parts. The product line includes two types of discs that differ by material: high-carbon cast iron GG15 and cast iron GG20. Both are GEOMET® 360 coated for long-lasting protection against corrosion. The coating does not affect the vehicle's braking performance, is effective at dissipating heat, and looks great together with alloy wheels. In addition, the parts do not need to be degreased before installation. Using these products as part of the RIDEX PLUS braking system ensures the highest level of performance.
