If you wanted "lift kits" you'd need to have an option for changing the spring datablock of the vehicle to something which has a longer spring length. Larger tyres are possible already.
Add a customizable fork lift where you can trade out the fork for like a big machine gun and trade out the wheels for rocket boosters and trade out the cab for a floating pod and trade out the exhaust pipe for a lazyboy chair that hooks onto the back of the vehicle. :):):):):):):):):)
Could it be possible to make a vehicle "player's vehicle". Then the player could spawn that vehicle and change the main car shape and bumpers and such? That way everyone could have their own car that they could spawn and was only customizable by them. So the car would be saved server sided and when you spawned that car it would spawn all of your colors and pieces with it.

You ever think about making damaged car parts?
