This is a special part to restore the ideal roll center geometry for EF8.
The lower arm angle on a lower ride height vehicle tends to be far from ideal 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 ideals suspension geometry.
★ Reduced roll
★ Increased stability of the tires
★ Sharper steering response
★ Faster cornering
The product is designed from the enormous data and knowhow from the actual racing participations.
After the countless testing, the product thickness is set at 20mm. The roll center adjuster is designed for the vehicle whose ride height is reduced more than 40mm.
※ It is not recommended to the vehicle with the ride height from stock to – 40mm.
A pressing is required for the installation.
The installation at the professional facility is highly recommended.
A proper alignment adjustment is required after the installation.
Please apply the correct tightening torque.
