Koni Double Adjustable Struts/Shocks built and revalved by ProParts USA (Jeff Wong) in 2013 for Don Slevin.
Significantly more rebound than OTS valving - if you're trying to lock down your front end in FStreet autox (I was), this is the ticket!
Original build sheet/invoice and dyno sheet...
Yes, still available - also, American Muscle lists this same wheel for all 05-14 (and also fit and cleared the 6pot brakes on my 15) so it should bolt up fine.
