I have an 05 gt that I'm trying to get the rear suspension just right The car came with Roush shocks. Seemed ok but just a little soft particularly on little g out dips. I bought a set of koni yellow. Seemed ok but still a little soft on compression even compared to Roush. Plenty of rebound. I then saw tokico d spec on Amazon for $33 a piece! I just got 2. I have a lever I attach on the bench to test up and down. I can't feel any difference at all turning the Allen screw. Soft comp and really strong rebound at any setting. Turning the screw is so loose with no tension at all. Any ideas? Is this normal for tokico d spec?
