Nismo VS Sport Package Springs, Struts and Shocks

nis350

You are obviously making assumption that the Swift springs are progressive and they are not. You're making statements without the fact and experience.

There are many people here have Swift springs and like them.

'Performance' is very subjective, but if you are referring to pure tracking duty, I doubt that any after-market springs with stock shocks are good enough. You probably have to spent tons of cash and replace most of the suspension components and 'TUNE' it according to the type of track.

All of the after market springs such as Swift is for those who want improvements over the OEM's with fairly low cost and Swift is one of the better one for that purpose.
