you'll see...
KW Variant 3's are very good. I ran them on my 09 Cosworth supercharged Miata. The goal with my Z4 is to build a streetable track capable car. From many years of race car experience I kept the stock springs and focused on shocks and sway bars. I found a good shock in Koni FSD's ( Frequency selective damping) which I'm currently running. They are soft for high velocity bumps like road potholes but are very stiff for slow speed movement like when cornering at the track. I'm running 18x8.5 front and 18x9.5 TSW Bathurst wheels with Firestone Indy 500 tires, 235/40 front, 265/35 rear. Note these are rebranded Bridgestone RE 003's sold in Australia and southeast asia. Very good tire. Worked great first time out at Sebring. Note how flat car corners considering stock springs.
