Also just received the Ohlins from Jubu a few weeks ago, and finally had time to take them to the track this last weekend. Very high quality product and the mounts that Jubu makes are well thought out and well manufactured.
Spring rates are 500lb/in
The dampers though have a HUGE range of adjustment. I've played with a few settings.
26 clicks on compression and rebound. (clicks below are from full soft)
1 click feels like a toyota, super super underdamped and nauseating
7 clicks on both is my ideal street. Tires feel good on asphalt and concrete, damps after one compression rebound cycle
13 clicks is very stiff. It feels like a go kart and damps out seemingly before the spring gets to full compression. In my opinion too stiff for street.
Normally on adjustable suspension you get some range, but the Ohlins are massive, which means you can really tune your car to you. I drove Buttonwillow's the circuit at my street setting and next time would probably go up a few clicks on a well paved track.
Overall, these are a huge improvement over the stock sports suspension that has lighter springs, but yet is too stiff for the street... because you have so much meaningful adjustability to play with. Would recommend.
