Thanks for the offer and if the rear spring did not change the rear ride height I might take you up on that offer just to try it out. For our track rental we will have two '03 track editions, one with S-tune suspension and mine with the Nismo suspension that a friend of mine are going to both drive to see what we think of each others set-up. It won't be an apples to apples comparison as our control arms, alignment settings, and tires will be different but should be fun.

Back on topic, to the original poster I would not hesitate to pick up the 2007-2008 Nismo suspension shocks/springs up for $400.

 

thanks, i'm just torn between these and some real coilovers. and would love to save this car (#64) or at least take everything minus the air ride
