I originally had 12 clicks rebound on the rear, but when I installed the lighter LSS wheels I
increased the compression. The LSS wheels and Toyo R1R tires are 6 1/2 lbs. lighter, each!
I set things up by turning all the adjusters fully in and then counting the clicks while turning the adjusters out.
I'm sure you already know, but the rebound adjusters are on bottom of the shocks and the compression adjusters
are on the reservoirs. As I said these setting are a little soft for some, but I like on our crappy roads.
I increase the compression, about 2 less clicks, and increase rebound, about 4 more clicks, depending on
how bumpy the track is, when I track the car.
Hope that helps. I'm pretty happy with it.
Depends on which set of Ohlins you have; I think there are 2-3 variants each with different spring rates / valving. Check the markings on your springs to tell which ones you have (the rates will be in Nm). That will determine which set of those instructions will work best for you.
For rebound full hard is clockwise looking at the shock which way. I assume clockwise looking down from the top of the shock? Reason I ask is that in checking what the setting was from the factory on my 2011 S240 it was almost close to full soft which seemed backwards. Made we wonder whether I had the clockwise orientation correct.
The adjustment on the shock is confusing for full hard. There is a pictoral that I used that has a yellow circular arrow demonstrating clockwise from the correct view.
The setup I used worked well with the corresponding spring rates.
I might have a touch too much toe in for the rear though. .16 deg each, not mm. The rear tucks, then grabs in its eagerness to turn in. Similar to my Tony Kart however. Might be better suited on a short track with several quick LRL or RLR's.
Ok, after much internet searching I found a couple posts and pictures. As far as I can tell it's the opposite of what my thinking was. The direction of clockwise for rebound damping in the specs is from the reference point of looking up from the the end of the shock closest to the ground.
