I noticed some cats can't be modified from certain areas one of the honda civics you can't change the back bumper, or add a hardtop to the Mazda miata. It's also kind of pointless to add a supercharger with a blower on the super builds if the blower doesn't actually work plus there's no actual supercharger cards in the game only turbos. It would also be nice to be able to change seats or add a roll cage, or for the driver to actually move his arms to shift or pull the e break. It's almost 2018 and I still have yet to see that done on a need for speed game. Also why don't we have front wheel drive drag cars in the game?
