The ZHP knob is a definite must buy. I just got the UUC SSK installed, though, and makes driving infinitely better. Probably the best mod I've done to date, and I've already got Dinan intake, pulley, software. Thinking about clutch spring delete. Anyone think it is easy to DIY? Do you recommend it?
