HKS Hypermax RS Performance Coilover Suspension 1998 - 2005 Lexus GS300 / GS400 / GS430

The all-new Hipermax Racing Sport (RS) coilover suspension kits are the first Hipermax line to be engineered as a truly global suspension system. HKS suspension engineers’ spent over a year developing the Hipermax RS, testing on various race tracks throughout the world, auto cross events and street testing in both Japan and the United States.

The result of all this testing and development is a coilover suspension system that has been precisely valved to dramatically improve handling at a competitive track level, yet still be comfortable even on the harsh road conditions in the United States. HKS was able to achieve this versatility by using an F1 inspired single tube structure coupled with an oversized piston and dual oil and gas chambers. A shortened cylinder body allows suspension travel to be maintained when the car is lowered. The Hipermax RS also features HKS’ trademark 30-way dampening and rebound adjustability that is adjusted simultaneously for easy tuning. The included anodized aluminum upper pillowball mounts improve steering response, traction and offer a more direct feel to the driving surface. On certain applications camber can be adjusted on the upper pillowball mounts. All HKS Hipermax RS coilover suspension kits are built in-house at HKS Headquarters in Japan.

HKS HI-Power Performance Exhaust System 1998 - 2003 Lexus GS300 / GS400 / GS430 Dual (Rear Section Only)

Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated applications. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.

For turbocharged applications, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles also benefit from greater exhaust flow capacity as engine tuning levels increase. Certain applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler. Like Drager Exhaust systems, Hi-Power Exhaust systems are made from SUS304 stainless steel muffler and tip assemblies. Depending on the application, Hi-Power muffler tips are 96mm, 115mm and 120mm in diameter, piping diameter ranges from 55mm to 95mm. Special Edition HKS Carbon Titanium Hi-Power Exhaust systems are exclusively available for certain popular applications. These exclusive versions of the Hi-Power Exhaust consist of a carbon fiber wrapped muffler shell, titanium tip, and polished SUS304 stainless steel piping.
