General Question

[LexSC400328]

hey everyone i have a pretty good idea of engine components and stuff exhaust, intake, headlights, but i really am clueless about suspension mods.

could someone please tell me like the basic components of a suspension and what exactly a "coilover" kit is...

and i'm not asking about specific kits either just in general for a stock sc400 with stock rims what height of lowering would be okay without having rubbing issues and turning radius limitations.

thank you all :)
