DC5 Lower Arm Pillow Bushing Kit
Prats# HCL-T5 Price $759.00

Our Kit includes two pillow bushing for front compliance and two pillow bushing for the front lower arm. A high powered FF vehicle frequently suffers torque steering, especially a tuned DC5 with negative camber lacks the straight stability and a stable front movement upon acceleration.　
J’s Racing believes that the cause is that the stock caster angle is almost vertical. By utilizing the pillow bushing on the front lower arm and on the compliance and off-setting it forward by 5.5mm, the resulting high caster angle enhances the straight stability and reduces pitching (vertical shaking). Furthermore, the pillow bushing provides a more stable cornering and an increase of the mechanical grip and sharper steering response by limiting the alignment movement

[Torque steering is the influence of the engine torque on the steering for some front-wheel drive vehicles. For example, during full acceleration the steering may pull to one side, which may be disturbing to the driver. This either causes a tugging sensation in the steering wheel, or else the car veers from the intended path]

DC5 Special Tie Rod
Parts# TRD-T5 Price $414.00

Our DC5 Special Tie Rod is a reinforced tie rod and tie rod ends to replace your stock tie rod and tie rod ends. When you set the front camber more than 3.5 degrees negative for sport driving, the stock tie rod dictates only toe in position (positive toe). J’s Racing special tie rod is shorter than the stock and makes it possible to adjust the toe angle to the ideal position. For the extended durability the products is made three times as strong as the stock parts.

DC5 FF Roll Center Adjuster
Parts# FCJ-T5 Price $277.00

The roll center adjuster corrects the roll center geometry and achieves the perfect setting you desire. The lower arm angle on a low-built car tends to be far from ideal and the roll center point can move to a far lower position. The deviation of the roll center from the center of gravity results in a deteriorated cornering force due to the increased body roll. The roll center adjuster rectifies the situation and produces the ideal suspension geometry.
[Results] Reduced roll, increased stability of the tires, sharper steering response, and faster cornering!

This product is to be used for DC5 whose height is reduced more than 30mm.
