Yokomo YD-2S rear toe control system
From Yokomo is this new rear toe control system that will dramatically improve the running performance of the YD-2S series. By installing a kingpin shaft on the rear hub carrier and connecting a linkage for toe control, it is possible to change the toe angle in response to suspension operation. Aluminium lower caster blocks, aluminium hub carriers and graphite arm plates are used for light weight and high rigidity. The damper is also mounted on the front side of the suspension arm, which reduces the weight of the rear overhang and gives it a racing look. For example, if the suspension is set to “Bump-in” which changes to “Toe-in” when the suspension is sunk, the car will have smooth turning performance at the entrance of the corner, but when the throttle is turned on at the exit of the corner, the car will accelerate with more rear grip. When the car is set to Bump Out, the rear grip is increased to facilitate acceleration, and when the car is set to Bump In, the car swings out dynamically from a stable straight to create a drift with a long distance. Also, the toe angle can be easily adjusted without steps, which greatly expands the range of settings.
