For those seeking a high-performance coilover solution, BILSTEIN offers the B14 (PSS) and B16 (PSS10) suspension systems. Both kits have the ability to adjust ride height, and feature a lowering range of 10 to 30 millimeters for the front and rear axles. These extremely durable coilovers are coated in BILSTEIN's patented Triple-C-Technology surface coating, contain aluminium alloy spring seats/lock rings, and quality high-strength sport springs. Additionally, B16 Coilovers feature a ten-stage rebound and compression damping adjustment via an easy-to-use knob. Damper and spring rates for these kits were developed on the famed Nurburgring, and are specific to the FR-S and BRZ chassis. A TUV certificate is included with the suspension package.
