Hi All,

We recently introduced our new RR Racing Penske coilovers for the ISF. That said, we are looking for an IS350 owner who tracks their car for feedback on our IS350 setup... if anyone is interested, we can extend a discount, BUT we are interested in serious performance minded folks, not "how low can you go:-)"

Some details:





thanks,

Rafi

I track my car out in CA (Fontana, Streets, Big Willow, Luguna).

Question:
1. What are the spring rates
2. How are you designing the damping perimeters (Rebound / Attack / Stiffness)
