Product Details
RS-R Basic-i Active coilovers for the 2014+ Lexus RC300 RWD (GSC10) are the value-priced entry into RS-R’s OEM-AVS-compatible coilover family. Same preset monotube damper, same Ti2000 springs, same pillowball uppers as the Best-i Active — with factory-tuned damper force (no dial adjustment) and a tighter price tag for drivers who want the AVS compatibility without the flagship price.
Basic-i Active is the value-priced sibling of Best-i Active — same factory AVS/DDS compatibility and monotube construction, with preset damper tuning and a tighter spec sheet for drivers who want OEM-electronics-compatible coilovers without the full flagship price tag. Retains the factory driving modes, retains the stock controller, and drops the car cleanly.
