I asked Robbie Collins about the weight (on Starting Grid). He said he'd find out next week. Personally, I hope it's heavier than stock. My car is barely race legal in it's stock form. I'm in the process of lightening drive train components, so I fear I'll be seriously underweight. Hopefully the new chassis is heavier to give me back some of the weight with the added benefits of it not being on rotating mass and it being low to help the CG.
