The Gear-X gear set has much stronger gears and shafts that can take up to 600 hp. The gear set is a synchro gear set with helically cut gears so it can be used for street driven cars if needed.
The Gear-X gear set is a direct drop-in replacement for the stock gears and is a great heavy duty set up for high-powered K engined cars.
OS Giken did some custom set up tricks when taking the car's power level and type of tires into consideration.
From Spoon Sports Japan, the car had very stiff springs and shocks with a low amount of damping. Although this seems counter-intuitive it worked surprisingly well with a very flexible chassis. With a stiff cage, the springs were now way too stiff and the shocks hopelessly under damped.
A call went out to KW Suspensions who built a set of custom 3-way Motorsports dampers for the car in record time.
This is a good method of mounting the springs as it isolates the dampers from spring kinking forces and can actually contribute to less tire shock due to the binding effect of the spring kinking force on the damper shaft.
The rear remote reservoirs are mounted inside the trunk area of the car and contain the high-speed and low-speed compression damping. adjusters. The rebound adjuster is on the top of the damper shaft.
With all of the adjusters close together and easily accessible, set up and tuning is much easier and quicker in the pits.
The front strut remote reservoirs were mounted on the inner fender panels to ease access to the high and low-speed compression damping adjusters. The rebound damping adjustment is found on the end of the strut housing above the front axles.
Since there was not enough time to test and set up the car, the Superlap Battle was treated as a test and many suspension changes were made during the event. Not ideal but the huge adjustment range of the KW dampers helped tremendously.
