New set of wheels...
Sp2's are relatively quiet I believe. It's not nearly as loud and obnoxious as the N1, at any rate... though I think open header might actually be quieter than a car with an N1; not really sure how that works lol
Ground Control coilovers, race valved Koni Yellows. Open up the fork on the front spindles a little to get the strut to sit a little lower and flip the spring perch upside-down on the shaft while adjusting the yellows to the maximum drop they allow. Then buy extended top hats. If that's not low enough for you, you could always remove the springs altogether
