S2000 Rear Roll Center Adjuster 12mm
Parts# RCJ-S1-12
S2000 Rear Roll Center Adjuster 20mm
Parts# RCJ-S1-20
Price $406.00

A lower arm angle for a low-built car will move the roll center point to a far lower position from the center of gravity and is far from ideal. The result is a deteriorating cornering force from an increased body roll. The roll center adjuster corrects the low roll center point to an ideal position.
Effective for: 1) Reducing the body roll 2) Increased stability 3) Sharper steering response 4) Enhancing the cornering force.

[For an S2000 whose vehicle height is reduced by 20mm-50mm, use a 12mm Roll Center Adjuster. For S2000 whose vehicle height is reduced by more than 40mm, select a 20mm Roll Center Adjuster.]

A concern of the S2000 setting is a limited adjustable range of the front camber. J’s Racing camber joint provides extra degree of negative camber by de-centering the lower ball point. L1 and L2 have a roll center adjustment function to correct the front roll center position for S2000 whose height has been reduced more than 40mm. L1 and L2 come with an adjustment plate. By removing the adjustment plate, L1 and L2 can be used as S1 and S2 for a S2000 with the ride height up to 40mm down.

S1 - Extra 2 degree adjustment for a S2000 with a stock height up to 40mm down
S2 - Extra 3 degree adjustment for a S2000 with a stock height up to 40mm down
L1 - Extra 2 degree adjustment for a S2000 with more than 40mm down (can be used as S1 without the adj plate)
L2 - Extra 3 degree adjustment for a S2000 with more than 40mm down (can be used as S2 without the adj plate)

S2000 Pillow Rear Control Arm
Parts# CAM-S1 Price $673.00

Utilizing high performance pillow balls on both ends of the rear control arm, enables a driver to find the best combination for the height, toe angle, and the camber angle.
( 1) The pillow balls eliminate the unwanted angle change and produces direct steering feel and greater stability.
(2) An adjustable end shaft provides freedom to control the bump steer. A lowered S2000 distorts the position of the control arms and invites frequent bump steer from unwanted toe movement. With this product, you can restore the control arm position to horizontal and reduces the bump steer.
(3) Adjusting the length of the control arm, you can set the best camber angle for your S2000. The set includes a left & right rear control arms.

S2000 Pillow Tie Rod End Set
Parts# PTE-S1 Price $492.00

When you reduce the height of S2000, the angle of the tie rod end may become too steep and the impact on the toe might produce an unwanted movement of the suspension. This adjustable tie rod end corrects the suspension geometry and will significantly reduce the bump steer. As a result, it increases both straight and cornering stability and steering response.
