This is a special part to restore the ideal roll center geometry for S2000.
The lower arm angle of a lower ride height S2000 becomes separated “V” shape and the roll center point moves to a far low position. The deviation of the roll center from the center of the gravity results in a deteriorated cornering force due to the increased body roll. Furthermore, the reduced suspension stroke leads to a diminished performance at the limit.
The J’s Racing roll center adjuster rectifies the situation by restoring the ideal roll center position (minimizing the deviation of the roll center and the center of the gravity) and produces the ideal suspension geometry.

After the countless testing, J’s Racing decided to offer two thickness -12mm and 20mm. Please choose the correct one based on how much ride height is adjusted on your S2000.
S2000 w/ ride height lowered by 20mm to 50mm -- J’s Racing recommends 12mm Roll Center Adjuster
S2000 w/ ride height lowered more than 40mm -- J’s Racing recommends 20mm Roll Center Adjuster
It is not recommended to the vehicle with the ride height from stock to – 20mm.
Please note that the roll axis (the line between the front and rear roll center) angle is another very important factor in S2000 setting. It is extremely important that J’s Racing Front Camber Adjuster L1 or L2 is used with the rear Roll Center Adjuster 12mm or 20mm.
