Suspension is always a tradeoff. The more precise it is, the less forgiving it will be. A coilover kit bolted on but not carefully setup and corner balanced by an experienced tech is often a lot more uncomfortable to drive and slower around a track. Get the rear of the car too low and she wallows like a pig. Experience matters if you want to get it right.

Some very broad recommendations:

*Mostly street/DE car on street tires: Stock suspension or M030 tuned kit

* Dual purpose street/track car on R-comp tires: M030 or PSS9s (carefully set up)

* Full race car on racing slick tires: Fully adjustable coilovers (JRZ, Moton, Penske etc. carefully set up and corner balanced), fully adjustable sways, GT3 adjustable "A" arms, trackside support for suspension tuning and adjustments at each track.

The basic theory here is... essentially everything revolves around our tire choices and contact patch. The higher the tire grip level, the greater the lateral forces and the more lateral control we will need from our suspension.

This is of course only one drivers opinion and others will surely disagree. YMMV
