Default suspension for track use?

Tracked my Z for about 6 years now. It came with Tokico D-spec with unknown springs when I bought it, the car felt stiff and I liked it alot. But later decided to change to KW V3 to learn the rebound and compression setting, it is a lot softer than I thought even with full stiff on the hotchiks sway bar.

I am thinking either pick a stiffer spring on the v3 or buy a new shock & spring which can at least 20% stiffer than v3. Any suggestion will be appreciated.

What are your current specs on the V3s?

Without knowing what springs you were running on the d-specs its only speculation, but the KWs are a soft setup overall being that they are street/track oriented. But they can benefit from a spring upgrade just like the Bilsteins, which also have a progressive rear. You would be surprised how just a linear rear upgrade will transform the experience.

If you are turning up the damping to counter a car that has a lot of roll and you have big sway bars already, then you need to make a change...because at max setting those KWs are not acting how you want them to. You need more spring. And probably more damper control.

If you are regularly tracking on a good tire, I would probably sell the KWs and look for something more aggressive. If your car is dual purpose I wouldnt let that scare you either, since there are several good options.

I made a lot of adjustment, lost on tracking the #. but I believe rebound F/R - 11/13. compression F/R - 11/10.

My car is a dedicated track car. Ave. 3-4 trackdays per month. Tires are NT01. I plan to do time trial next year, so I would prefer not to use coilover since V3 can bump me to an upper class. Do you have any recommendation on the shock and stiff spring setup?

3-4 days per month is a lot of track time. And NT01 are sticky tires.

No coilover? So you need to run a non-height adjustable setup? That changes everything...
