I will be around until the 7 April as well ... You have my number anyway, just sms or call.
I don't have the Ohlins with the reservoir (Nismo R-Tune are Ohlins, btw) ... The one I have has the bump and height control only, and it's going for around 15k new ...
The closest I can get you to the Ohlins is, I may swap the original Ohlins springs with the HKS. The Ohlins I have are the least comfortable suspension I ever had. I think the current Ohlins spring matches with the softer HKS shocks may give better control, and using a softer springs for the already heavy-tuned Ohlins will at least gives more play for the bump controls on the shocks.
In that case, I'll bring those shocks back ... No obligation anyway, will knock a few hundred off the price listed since you may
BE ABLE say bad things about me to some of my very close "aquaintances". Again, no obligation ...
