Kawahara MRX4-R chassis plate PRO
Kawahara, the Japanese tuning company, have shown these drawings of their upcoming release for the MRX4-R. This PRO chassis is narrower than the standard version and features inserts for stiffening up the chassis, similar to the LCG chassis from Serpent. It mentions something about being able to use weights in place of the plates, which could make sense, and also they offer droop blocks with pins that correspond to holes in the chassis so you are sure that your car is always sitting flat when applying your setup. This chassis plate is available as a complete set or as individual parts and should be available in the middle of March.
