Smokem is proud to introduce our RS carbon fiber chassis for the Xpress XQ1 Mid-Pulley Conversion Kit (XP-10495).

The RS chassis features soft weave carbon fiber material to significantly increase chassis flex compared to the stock Xpress chassis - increasing the overall grip and widening the tuning window of the car.

There are also minor changes to the profile shape to fine tune the flex points for increased stability and corner speed.
