Good evening, everybody. First of all, I would like to say a greeting to the direction of the community, since I am new Hope it will be an informative time I have a big problem with my shock absorbers. This problem must be done by 10.10., because I have to drive with the car c.a. 1500Km within 3 days. To my problem : I have installed a carhifi system. This has a total weight of c.a. 550Kg. Of these 550Kg lie c.a. 380Kg alone on the rear axle of the vehicle. My car-interior is therefore bagged together and has only 4-5cm ground clearance. My car has even lost the exhaust by hitting it on the ground I was at a specialist workshop today, because I assumed that the springs are sluggish. They said with there that I had Koni shock absorbers. Furthermore I have Pro rear axles 2! springs. The springs are not the best but certainly not bad. So it could not lie on these, because I closed the door. The fact that my car sucks in in the back is the “inflict” of my shock absorbers that are not supposed to be good. He said the following: You need “pneumatic shock absorbers” because you can pump them in with air. You can only be sure with Pneumatic shock absorbers that you can get back up with these carts back up. You can “pump up” these shock absorbers until the car is reasonably high again and I no longer use the lower back. oden Aufsetze. Normal shock absorbers would never hold this weight. (man’s statement ) Now I have no idea what the parts look like, and what exactly I need there !? As I said, it is not about driving behavior or anything else. I want straight away that my car comes up at the “po” again, and it looks like with any other “normal” vehicle too. I know that the weight is hardcore, but there must be some solution ? where do I get so pneumatic shock absorbers from ? Is this all true with “You can fill in the air, so the car goes up” ?? Would really be great if you could help me further and I can order this week. The car : ( depreciated from the vehicle registration ) Omega A Caravan 2.0L engine capacity 85Kw ( 115Ps ) First registration : 18.08.1993 Type number : 0039 Key number : 685 Greetings Norbert
