Ohlins DFV Review

FWIW I went 1.3 seconds faster at New Hampshire Motor Speedway chicane-chicane with the Ohlins DFV in my FD street car with no other changes, vs. the Tein SS coilovers that were on it. HUGE improvement in ability to take outside curbing at full throttle at 11B (leading onto front straight) 
I've driven at this track since 1999, dozens and dozens of track days there, so improvement is not due to driver improvement.
IMO ability to separate out compression and rebound damping isn't as necessary if the damping is tuned to the specific application, I believe this is the case with the Ohlins Road & Track coilovers. I wound up running 6 clicks out front and rear on the street (homed in on this after starting at 10 clicks), and 4 clicks front 5 clicks rear at the track. Compression/rebound damping seem well-matched at the settings I've tried.
On the street the difference is TREMENDOUS. The car went from being a total PITA, slowing to a crawl and driving around any minor bump/pothole, to being a total joy, taking road imperfections with unabated speed. Like riding on a freaking cloud in comparison, despite much stiffer spring rates (+22% front, +57% rear).
It was a big gamble for me, but well worth it. I LOVE the way the car rides and handles now.

I've just bought some DFV to replace my 2 way Nitrons. I'm not too fussed about them just having single bump and rebound adjustment, but if I don't get on with them I will upgrade to TTX. I've got a lot of VBOX data which I will be able to compare the Ohlins with.
I've had 2 way Ohlins on the Exige before and they are incredible. I've no reason to believe the DFV will be much different.
Just hope they can stand up to 40 minute races without remote reservoirs.

Thx guys, very helpful input. Crossing off the KW's in favor of one of the other 3 options. Leaning toward AST because of rebound adjustment & future ability to convert to double adjustable. I like that I could get Bilstein's compression valved to match my spring choice tho from the get-go, while both the AST an DFV options would just be "dealing" with the higher rates until revalve time.
