Yes, see posts #455 for the spring list and #457 for which Tiguan rear springs I bought (AG). There are A LOT of different Tiguan rear springs. According to the specs from there, the thickness of the metal is the same diameter as the towing springs, but the overall length is 21mm shorter (about 3/4 inch unloaded, about 1/2 inch loaded). I don't remember if that makes the spring slightly stiffer or softer than the towing springs (someone can chime in here if they want). From what I read, the towing springs are about 190 lbs. and the stock springs are about 145. I don't know the strength of the springs I have.Your using Tiguan rear springs correct? How do you think the Tiguan konis would pair with the jsw towing springs? The tow springs are even taller than the Tiguan springs, correct?
Where did you source your sway bar?
Regardless, I think the Tiguan Konis would be good with the towing springs if those springs are no stiffer than the Tiguan springs I have. If you want to experiment a bit, I'd find someone selling some lightly used Tiguan OEM rear struts for cheap and try those...might be worthwhile. With the extra height of the towing springs, I think you want a little compliance in the rear end, otherwise IMHO the car starts to feel a little tipsy and has a little more understeer.
How do you think your car feels right now? Can you can push the rear end down easily (I could with the Jetta Koni SA in the rear)? Does it feel wallowy in the rear on the freeway?
