How to get rid of "waggle" w/o sacrificing ride?

and if that doesn't solve, then:
A) step up your front sway with a Hotchkis
B) start saving to upgrade your shocks/struts and springs - you will want adjustable dampening shocks and stiffer springs.
IIRC stock Nismo is a 22mm drop over stock 370z anyway. 1" is 25.4 mm. even Swift Spec-R Springs are 1.25" lower than stock up front and 1" in rear. Upgrading to dampening adjustable shocks will give you the ability to firm up your ride
C) check your control arm and trailing arm bushings - they may be shot and need a replacement/upgrade to polyurethane of a stiffer quality. Depending on how hard you drive, you may have pushed these past useful realm already
D) depending on age and mileage, may even want to check body bushings for same

My touring model doesn't float that much on hard snaps, but I also only have 15k on it, so .... there's that. Are you talking track speed sway or DD snap sway?

my .02 - i very well may be full of total shiite and no clue what I am talking about either
