S2000 ROLL CENTER ADJUSTER
Another common suspension geometry issue on a lowered S2000 is that the roll center gets altered to a lower position from its original height which impacts the amount of body roll in a corner. The higher a roll center is positioned, the closer it is to the center of gravity, resulting in less body roll. The lower a roll center is positioned, the further it is from the center of gravity, resulting in more body roll.
The EVS Tuning Rear Roll Center Adjuster features a lower ball joint that has been extended by 15mm over OEM.
This repositions the control arms back closer to their original position, resulting in increased cornering performance, decreased body roll, improved tire contact with the road, and increased steering wheel response.
S2000 FRONT OFFSET CAMBER JOINT
The EVS Tuning Front offset camber joint replaces the original lower control arm ball joints.
By moving the lower control arm by ¾ of an inch lower, it changes the control arm’s angle, which raises the roll center and reduces body roll.
Not only does this correct the front roll center, but it provides additional negative camber in the front by up to 3 degrees.
To extend the life of these ball joints, we used aluminum heat wrapped to help deflect heat coming from the brake rotors. Especially if you remove your brake dust shield, you will likely damage the boots when you track your car.

ZOMG there’s no split pin on the ball joint/castle nut on the AFTER picture!!!>!ONE1BBQ
Thanks for the catch! We’ve updated the image with the cotter pin.
A car’s suspension is a system: when you change part of it, other parts are also affected. Often, lowering a car looks cool and might improve some aspects of handling, but it affects other things like roll steer, control arm angles, bump steer, etc. We did a lot of similar adjustments to the two S197 project cars here at MotoIQ: bump steer correction, control arm angle adjustment, differential/drifeshaft pinion angle, roll steer, etc.
