Last week was p class racing and it was plagued with ballasted f1 cars. Im not the fastest in the world but it seems pretty global that there were one or two prototypes mixed with most of the f1s, and a second concurrent race of vice-versa.
I propose they ignore the ballast change for cars that started life above the intended class and only in the class lobby, especially since we only get one. One cant blame the racers as they have no other option for racing these in open lobbies. Ballasts make perfect sense in manufacturer races, division, time-period, or basically anything not directly grouped by pi. Hell id love to see a gt3 car only or a mixed division series with bop.
This is not meant to be a finalized idea as ive only protected cars which go above a threshold just to install basic tuning-lock upgrades. Theres also room for something like a no more than ___ pi difference to drop class. Again, for class lobbies only and only if were going to have a single rotation at a time
