How can I create a single car with different settings?

Hello, I have a project of a rally game for mobile and would like to know how can I create a car with different selectable settings.

In real life, in asphalt rally, cars use rim 18 "wheels, low suspension and rigid springs. Already in the gravel rally, cars use rim 15"wheels, high suspension and soft springs.

In my game will have both surfaces and I wish to have the car set up correctly for them (asphalt and gravel).

(I have the 3D models of cars and the different wheels)

A good example is the game CarX Drift Racing " - You can select different setups for every car "

NOTE: I know how to set up the car, but do not know how to get different settings for a single car.

[I'll be using Edy's Vehicle Physics to set up the car.]
