XTREME CAR DRC UPDATE KIT
DRC Update Kit for Xtreme Car
We are happy to introduce for the TTX30 the WRC developed Dynamic Rebound Control, DRC.
This feature adds traction and smoothness to the car and allows you to close the rebound adjuster
without losing traction and with that the possibility to reduce spring rate to gain even more traction
without losing body stability.
Each kit contains parts for 4 dampers.
