I questioned the Sachs stuff right away upon receiving my Weitecs whenever it was ... like eight months ago maybe? The fact that I got a Sachs Super Touring strut/shock didn't really matter to me as much as the fact that I didn't expect it, so I can relate to the original poster's concerns. I came from a stock setup, then to Bilsteins/H&R, then Weitec. I agree with the opinion that they are stiffer and better handling than stock, and less harsh and not as good at handling than the Bilsteins/H&R setup. However, I really think that the "stiffer than stock" feeling comes mainly from the springs, not the Sachs. Are they matched and balanced? They feel like it. Are they revalved and engineered? I seriously doubt it. The thing that miffs me most about the Weitecs is the whole rear spring situation in the sedan application. The rear springs from the sedan kit raise the back end too high, and the rear springs from the wagon kit lower the back end too much, causing the front end to raise too high. I have tried them both ways on my 850 since I have two kits and drive both a sedan and a wagon. I'm not happy with either scenario and it looks like I'm going to have to purchase maybe some TME (or other) rear springs for the 850 until I find the optimal solution. And I ask myself why did I spend 'x' number of dollars on this kit and now have to spend 'y' more to get it right? Because of this, I give the Weitecs a thumbs down. The Sachs issue is just icing on a bad tasting cake.
