Re: Rear Suspension
Bought my '97 with 21K miles and it had the rear sag. I replaced the rear springs at 110,000 when I had new struts installed in front and rear. it did not improve the rear sag. I guess that's just the way they were built.
Realize what we are talking about here is visual sag. Yes it looks strange but doesn't mean there is anything wrong.
I'm no suspension expert, but if it was designed with a certain amount of visual sag, jacking it up with shims, air bags, incorrect springs, etc. might unnatually change the weight distribution and thereby adversely affect handling and braking.
I always get a kick out of seeing these young guys modding their ride by playing with the suspension. I wonder if they realize how much engineering goes into making sure a particular suspension setup is safe.
Be careful what you wish for.
