Hi, I have today converted from my 2×102 ironman to 1x102er incl. VSD into supersound. The 2x102er was initially combined with the series VSD. Fits everything wonderfully, no problems. With the new 1x102er incl. VSD both dampers 1A fit to the vehicle. The VSD is however very large, so that it has some space up to the heat protection sheet only a few millimeters and therefore has to be aligned very precisely. Installation and alignment were done again quickly In one place however, But today I had serious problems: at the separation point between VSD and connecting pipe to ESD the pipes could not be stuck together. This did not fit in with the worst force and besides, you also have no place under the car to make such chin-ups. So had to grind with a flex on the tube from the VSD until it was thin enough to fit into the connecting pipe took me about 1.5 hours. I would be interested in how your experiences are like this. with the ironmen regarding assembly and possibly subsequent correction of the position of the ESD ́s/end tube?? Gruss Markus PS: my 2x102er is now ready for sale
