I would not recommend Teins for the track. The spring rates are not very stiff and they don't offer much strut adjustability unless you go with very high end kit from them where you can dial in rebound and compression separately.

The Koni Yellow and GC setup is the best bang for the buck and with custom spring rates, you can pick a rate that will be both comfortable for the street, but pretty aggressive on the track. If you are very serious about it, a stiff rate spring with a set of revalved Koni Yellows will out perform a set of comparably priced Tein coilovers.

The EDFC is a nice gimmick, but for the price, I will just get out of the car and adjust the shocks myself. It takes less than a minute, so the EDFC is not really saving you time.

I just upgraded from a basic KYB GR2 shock and Neuspeed Sport spring setup to a set of GC 350F, 450R Koni Yellow setup and it is like night and day. I no longer have traction issues and the car rides like it is on rails. The spring rate is still very streetable and with the shocks adjusted properly, it is probably more comfortable than the last setup.
