a minimum number of attachment points only.
Currently T2 is limited to a maximum of 12 chassis attachment points and T3-T4 are limited to 8

2020 cars exceeding the current number of attachment points will be legal with a weight penalty of 1.5%
to the base weight of the car. Data can be collected and, if appropriate, the weight penalty can be
adjusted to correct the BoP.
Starting in 2021 the weight penalty can be removed, and the rules rewritten to specify a minimum
number of attachment points.
