Stig- I remember reading a good article/thread a couple years back that, IIRC, involved David Borden. I don't think it was on this site. I will look through my saved items and see what I have.

For a car like the GTM, I believe you should limit your shock search to a monotube design.

I just picked up a set of Ohlins tt44s for the race car, but I will be the first one to admit that I am not a shock guru. I know what to adjust when things are not working properly at the track, or at least I know which directions to try, but the ins and outs of finite shock performance are so involved that I really don't have the time or energy to be an "expert". I simply pay someone who is to get the shocks close to what I need. Kind of like the engine tuning stuff. I could take a stab at it, but it would probably end up costing me more and my results wouldn't be as good, so why knock myself out? "A man's got to know his limitations".

The Ohlins company is very "open" about their designs and applications. See these links for some interesting reading about general shock theory, application, and function.
