Colin Chapman,  Lotus said if the car does not fall apart just after
crossing the finish line, it is too heavy.
Murry

That no longer applies because all road race cars have minimum weights
specified by the rules. This removes some of the challenges for the
designer. It also negates the advantage of the high power to weight
ratio of the rotary. One of the reasons I lost interest in racing
cars.

Paul Lamar

Yeah but .... the designers still go for absolute minimum weight and
then attach tungsten skid plates to the bottom of the tub to come
back to the minimum weight.  That lowers the CG and balances the
weight front to rear.
