I am looking to upgrade the suspension on my '04 C2 and was going to do the PSS9 until a buddy introduced me to the folks at RUF. Now I am a bit confused and am unsure of whether to go with the PSS9, or do the RUF version. There is a fairly significant price difference between the two, and thus I am looking for anyone who might have experience with both setups. Is there a noticeable difference between them that justifies the higher cost, or would I merely be paying more for the RUF name, were I to choose them.
