Product Details

RS-R Sports-i coilovers for the 2021+ Lexus IS350 AWD (GSE36L) balance daily-driver comfort with serious track capability on the same set of dampers. The 36-level single-knob adjustment, vehicle-specific spring rates, and full ride-height range let you dial the IS350 in for the commute on Monday and for a canyon run or track day on Saturday without touching a tool beyond the damper click wheel.

The Sports-i is RS-R’s foundation street-and-canyon coilover — a 36-level single-knob monotube damper built in-house in Osaka, Japan, with full ride-height adjustment and vehicle-specific spring rates. It is engineered to be driven daily yet firm enough for spirited weekend use. Backed by RS-R’s 1-year / 12,000-mile warranty and available as a rebuildable, serviceable unit.
