Hi arceye
First off were are you measuring this 28mm from ?
I just measured the RTR cars i got here and with the shock collars wound fully up and the battery in the ride height is about 12mm.
I have never had to add internal washers to limit the droop on the shocks on the 210 personally.
Have you got the little rubber bump stops on the right side of the cup ie the spring side ?
Also are the ball ends wound fully onto the shock shaft so you can see no thread.
