m030 spring rates

[Topless]

FYI
My PSS9 car is running stock PSS9 springs and does not pitch, nor is it overly uncomfortable on the street. I have been in other PSS9 equipped cars where they ran too much spring rate and were harsh and gave away grip on corner exit (excessive wheel spin). Getting the setup right is important with coilovers.

M030 is Porsche-tuned and you just bolt it on, align and go for 90% of PSS9 effectiveness. A lot of value for the $$.
