I have had my VW trike since February this year, i have been working my way through various things to get it as i want it.
I have just replaced the rear motorcycle shock mounting bushes, these are normal motorcycle shocks with springs.
While doing this i noticed that the eye to eye measurement is 14 1/4 inches while the mounting bolts are 13 1/4 centre to centre. This is with the VW rear torsion bar suspension in a neutral position.
To my way of thinking the with the motorcycle shock and spring with it's preloaded spring pressure plus the one inch of extra pre-load from the difference between the shock eye to eye measurement and the bolts mounting centres this is an incredible amount of spring pressure especially as VW suspension is designed for a whole car.
Now it could be argued that the stiffer suspension is because there is no anti roll bar fitted. All i know is that riding down the road and going over manhole cover that have sunk or are raised is nor a comfortable ride.
Any one have thoughts or better still any suspension wizards out there. If i remove the spring from the shock and just run with a damper would it wallow about on corners.
