About 6 weeks ago I posted about spring sag in the rear suspension of my 1993 Supra TT. The drivers side had 1 inch less wheel gap then the passenger side. Most people agreed that it was probably the spring sagging due to age and nearly 100,000 miles of use.

Well, today, I went ahead and did the rear suspension with KYB adjustables and Tanabe Super H springs. I'll be darned if the wheel gap issue is still there. Yes the car is lower, but the passenger side still had 1 inch more gap then the driver's side. I can't fit any fingers between the tire/fender on the driver's side, but can fit nearly 2 on the passenger's side. It really looks like crap.

I am at a loss.... I looked at the suspension and it doesn't look like anything is bent/broken. Does anyone have any recommendations as to what to look for, or has anyone had this problem before? I really don't want to go through the hassle of doing the fronts if I'll need to step up to coilovers to solve my wheel gap issues.

Thanks for any help in advance.

Tires are the same size so that isn't it. The back of the car looks really clean actually, no damage to anything that I can tell as far as the frame and everything-rear suspension parts look good too. I am going to go out and drive it a bit tonight and see what happens, perhaps it will settle down! If not, I may build a 1/4 inch spacer to put in between the strut housing/frame and raise up the driver's side 1/4 inch to make it look more even. Hopefully this will cause the pass. side to settle down a bit.


Thanks,

Steve K.

Thanks for the suggestions guys. I took the car for a drive this evening around the block and the wheel gap issue is still there. Also when I hit a bump the car sways horribly to the drivers side upon landing from the bump-not as bad as before with the stock 100k suspension, but still noticeably enough. I stopped several times and the wheel gap is much worse on the passenger side. So I am guess it is time to get the trusty FSM out and start taking measurements. How would the rear sway bar get preloaded? I haven't heard of this.

Thanks for the suggestions. Keep them coming if you can think of anything else. I gotta get this rear suspension deal figured out.

TTYL,

No,

The rear trunk area looks good. I am going to pull the wheels off this weekend and look at everything again. The alignment is good as I drove the car back from New Hampshire in November and didn't notice any weird camber where. The car also tracks straight as a whistle. It just sits a lot lower on the drivers side compared to teh passengers side.

Really that is not off the wall at all. I do have gap in the front passenger side fender and have a much smaller gap on the driver's side, so the drive's side spring could be sagging. This would also cause the rear passenger side to have more wheel gap. I am going to go ahead and replace the front springs/shocks in the next few weeks with the Tanabe/KYB combo.

We also found out that my pass. side rear wheel bearing is toast and will need to be replaced as there is 1-3 mm play in the rear wheel. I am going to go ahead and replace both rear wheel bearings in the next few weeks.

Thanks for all suggestions and help.

No,

Sway bar bushings are old. I am looking at replacing the sway bars with a good street set up.
