Thanks, it really Works instead of using Mercedes or Ferrari XML files and importing them to slower carsEasiest way for cars performance: change of chassis mass. Reduce for outsiders and increase for top's. It really works: if change mass of Williams from 750 to 650, they will immediately be on pole with 2 second advantage. It's just one number for each team in .erp files. Use Ego Erp Archiver and made it by himself. But performance of each driver is unmoddable - Hamilton faster than Bottas etc.
