Just a quick note regarding suspensions ad the comparison of Tein and Koni.
Last year I ran head to head with a stock ITR in auto-x and I had a 1-2 sec advantage over him over 7 events.
This year I put on my Koni 2way adjustable revalved shocks and stayed in D/S and he went with the Tein coilover kit ( which one I'm not sure but he paid as much as I did for my Konis), which put him into DSP.
Now I run Hoosiers and he runs Yoko 32's which explains the time difference but this year we have a 4-5 sec difference. I absolutely love these Konis and he hates the Tein experience.
BTW, the Konis at their lowest settings are slightly more harsh than OE and certainly streetable.
Also, what's the deal with Tein setup of hard front springs and soft rear...???? is this the Japanese way?
