First of all we should be able to put whatever tires we want on any car (except for maybe the nascar tires which is a neat easter egg exclusive to just a couple of cars). There’s no reason why we shouldn’t be able to put rally tires on a rallycross car, street tires on the new corvette or drag tires on the Reliant. These tire restrictions are nothing but a huge waste of potential.
Second of all we should be able to put drift suspension on any car we want. There’s no reason why we sholdn’t be able to put drift suspension on the Caterham, the Iron Knight and the old race cars. Why is it that I can put drift suspension on the Shelby Cobra but not on the Shelby Cobra Daytona or the Ferrari Testa Rossa? Again, a huge waste of potential.
For the third I would like to see lift kits. The off-road vehicles need more lift to look badass and to handle the thoughest terrains.
For the fourth I’d like to see more odd engine swaps. How about a Yamaha 800cc I4 2-stroke for some of the smaller cars? Diesel swaps, from the Nissan Titan or whatever? And how about letting us swap the elictrical race powertrain, that was available for the Tesla in FH3, into some cars?
