Well ok, lemme see if I can answer that. This is my logic: under what topic would you put suspension?
Performance? No, it does NOT add any power.
Appearance? No, even though it improves the exterior by lowering the car, thats not why people buy aftermarket suspension components.
So to answer the question we need to ask WHY people lower their cars?
Most people buy stiff stuff to improve HANDLING.
When is handling important: autoX, racing...
damn Im starting to sound like a geek, I think college is getting to me :(...
