Product Details
HKS Hipermax S Style X coilovers for the 1998-2005 Lexus GS300 RWD are a premium coilover solution tuned specifically for luxury sedans, executive cars, and higher-weight platforms. The S Style X prioritizes refined ride quality, body control through long-wheelbase corners, and a sophisticated lowered stance — matching the character of a car like the Lexus GS300 RWD.
