I'm in a jam here. I LOOVE my 2007 Cadillac STS V8 RWD, F55 Magenride, with Sport Suspension, I believe FE3. It's what I believe to be on of the rarer cars, 6 Lug Wheels and Hubs, which I've been told is from the CTS V, but mine are stock. Brembo Brakes front and rear. Not a V. All stock. EG Grille and Body Kit.
I love this car, but this is the worst ride quality I've ever felt in my life. I'm a used car dealer and I drove every type of 05-07 STS they sell prior to buying this one. MagneRide and Standard. All of which rode acceptable to me. Some better than others. I purchased this one, cheap, assuming the suspension was bad. 3 Cadillac dealers later, 2 independent shops later, all I've been told is my suspension is perfectly fine. As I said I'm a car dealer, and I drive more than my fair share of vehicles. Never in my life have I been in a car that rides so poorly. Even at 10mph, it absorbs no impact. Every bump shakes the entire vehicle. I feel no difference between Touring and Perf. modes. No leaks. No error codes.
My questions are as follows. Does anyone else feel the same way about their STS? Is there some mysterious issue that can go un detected to cause this? Am I just SOL? If this is "Just how it rides." Which I truly just do not believe. If that is so, is it possible or feasible, to convert this car to a softer suspension, say base FE1/FE2, but using a simulator computer and base STS suspension setup, magnetic or not.
I love everything about this car, minus the ride quality. I don't mind spending the dough to do the swap properly, if it's possible. As I said, I purchased this car at a steal of a price, from a man that just needed the cash.
Any help is greatly appreciated. Thank you!
