Rear Suspension Question

[mikebrewer1]

I have a 93 Cobra that I bought bone stock 4 years ago with 29k miles on it. I upgraded the suspension a year later with the following:

FRPP Progressive springs front and rear.
Mac Upper/Lowers
BBK Subs

Last year the Mac Upper control arms went on the driver's side with only 4k miles on them. I trashed the Mac Uppers/Lowers and replaced with FRPP uppers and Maximum lowers. I also replaced the stock rear shocks with KYB AGX adjustables when putting in the new uppers/lowers.

I've been working on another problem with the rear end this past week ( but won't get into that one ) and noticed that the driver's side suspension is softer than the passanger side.....at least it seems that way....

When I lift the rear from the diff housing ( in the middle of the pumpkin ) the driver's raises about 2" before the passenger side engages. Then, when the passenger side engages, the car starts to raise....there is almost no give on the passenger side. Also, if the car is on jackstands with the stands holding the car on the rear frame.....the driver's side will raise off the jackstand well before the passenger side.

Has anyone seen this? Is this normal, plz forgive me as I am a newbie....but trying

thanks

Not normal. Could be mismatched springs, bad shock, frozen bushing in control arm. Switch the shock/spring/arms from side to side until you find which part is causig the difference.

I've got three mustangs an 88gt 85 vert and an 95 vert they all do the same thing

All of the torque on transfered to the right rear corner of the car... This puts more wear and tear on this side of the suspension components. Now, I can not say if what you are experincing is normal because I never jacked up both sides at once but I can see it happening.

I might not help, but at least I have an explination for you.

even is they are not broken put new shocks on will make a huge difference, and if you really want it to handle good get the maximum motorsports coil over kit you will never regret it for a second, makes it a whole new car, subframes connectors are also a must
