Tein RA shocks and Springs
The stock R1 shocks are very firm, however the stock springs (used on both touring and R1) are a medium rate. The combination leads to a harsh ride that still has a little body roll.
The Tein RA shocks are 16 way combined adjustment for bounce and rebound. They are a race spec shock and the springs are more suited to the race track with 16Kg/mm front and 12Kg/mm rear.
The most noticable difference to the stock R1 and Tokico shocks was the feeling of control, these shocks show no after affect when hitting a bump, there is no bounce and the car is not upset.
I was able to reduce the oversteer that I was getting with the old setup. The Teins allow me to ballance the car with the height and dampening adjustment.
