okay first of all...

do you know how to drive your car? pushing it to its limits?

because all of the mods will be useless if you cant put them to use.
tires, tires, tires....

they are the ones that make contact with the road, not the suspension components.

ii had hella suspension mods to my car but my rear end would keep sliding out because i didnt know anything about tire pressure, suspension settings and learning how to dive into corners.
