I have kw's v2's and for performance driving they are still a bit too soft and the car still understeers, Same is would probably true with PSS9'S and others as from my research on average the after market kit's spring rates are all consistent with increases of about by 10-20 Percent above stock. Car is a daily, but I do autox and track days..
Being a Porsche owner also, it is quite common to double the spring rates
from stock. It is also easy to insert different spring rates onto the front coilovers. With the Benz there appears to be no such way to run a better preforming linear spring without making an adapter for the front coilover. I am probably go to have one made as i would like to try different spring rates. I want to see if i can tune the suspension to make the car reach a higher level of turning. IE lose the mid-to corner exit understeer.
Anyway, curious if anyone has made and adapter as it would be great to be able to run any off the shelve springs like a Hypercoil, Eibach, Swift etc.
