I had taken my car into a repair center recently and the service techs say I need a stronger suspension in the rear. I have never replacedanything for the suspension and apparently I'm being told my rear tires are being worn in a wavy pattern because of the extra weight from my stereo system and golf clubs in my trunk. I'm pissed to hear this because the weight I'd have to guess is like one (maybe two) person(s) consistently riding in my backseat to weigh the back down. It does appear to be a little lower but I can't seem to find where to find these stronger springs. They recommended places like U-Haul since they install ball joints on cars that they might also be able to install a stronger springer or something but I haven't gotten to them yet and I talked to a local dealer that makes custom car springs and I was told that he couldn't do it for this car (the guy that told me was amazed he couldn't as well). What are your thoughts on this?? Is this just crap since my car has around 140,000 miles and maybe just replace the suspension and I'll be fine?? I've found parts for lowering the car but I guess I am looking for something to hold the car to it's normal height under this added weight. Please help.
