Hyper-Street II Coilover Kit

The Rev9 Power Hyper-Street II Coilover Kit is engineered to enhance the suspension performance of the 1998-2005 Lexus GS300, GS400, and GS430 models with chassis codes JZS1 and UZS1. This kit provides a significant upgrade over stock suspension components, offering a more refined and adjustable ride. Key features of this coilover system include 32 levels of damping force adjustment, allowing drivers to precisely tune the rebound characteristics to suit various driving conditions and preferences, from comfortable cruising to spirited track driving. The kit also incorporates height adjustment capabilities, enabling users to lower their vehicle to achieve an aggressive stance or optimize center of gravity. Specifications for the Hyper-Street II kit include front spring rates of 10 kg/mm (560 lbs/inch) and rear spring rates of 8 kg/mm (448 lbs/inch). The front springs measure 180 mm (7.09 inches) in length, while the rear springs are 220 mm (8.66 inches) long, both with a 62 mm (2.44 inch) inner diameter. The use of mono-tube shocks contributes to consistent damping performance.
