I can't wait for these to become available.

Looks like they are available already on speedfreaks website

I talked with Anish last week, and he made it sound like they are still in the testing phases.

Yes, they are listed on the website but that is more of a placeholder for the time being since we are still testing and pricing has not yet been finalized.

What is the difference between these and the ones Urge is offering?

Matt, care to share who you have valving these and whether there's any particular secret sauce other than the natural adjustment in bump/rebound for the spring rates?

They are working directly with Ohlins on these. I think once we have done some more testing and they are happy with the spec they will be able to share the plots to those who are interested.

Thanks for responding on this, Andrew. Yes we are working directly with the Öhlins engineers on this- of course we could have simply told Öhlins or some independent shop, "valve them for X spring rate" and leave it up to them to simply modify the standard off the shelf valving package for higher rates (to my knowledge this is what Urge did with the DFV-R). However, we viewed this as an opportunity to tweak the valving package and push the focus towards lap times on track and worried less about ultimate comfort on the street (not that these are uncomfortable on the street even with their higher spring rates). The main objective from the beginning of this project was to create one of the fastest, relatively affordable single adjustable suspension setups for an S2000. I have been hesitant to post in this thread so far because I cannot give away any specifics of what we have changed at the moment. We have spent a lot of time, effort and money over the last several months going back and forth with Öhlins testing different ideas. The first testing of these look very promising as evidenced by Joel's awesome drive to a new TTC record but we have not yet officially finalized the specs for the production run. Once we do I will be working with Anish to come up with an explanation for what we did without just giving away all the details that would allow someone to copy these.
