Nismo VS Sport Package Springs, Struts and Shocks

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.

Yes you can pick up cheap 3000000 way adjustable damping "coilover" kits for a little over 1k but who knows what the adjusters truly do and you likely don't need them anyway. Koni yellows are not a bad option but I personally couldn't tell you what range of spring they were designed to dampen. Perhaps Koni will , and you can pair them up accordingly. And just to clear up a debate here. Swift makes both progressive (Type R) springs as well as linear (Swift Race Springs) for the 370. You can tell them apart visually with a glance.
