I have a 2005 with 100K+ miles and noticed my read driver side body height is less than the passenger side. Measuring roughly there seems to be about an inch difference in clearance between the height of the tire and the body.

Would this be caused by rear struts being worned? or something else.
Is this height adjustable?

I would appreciate any suggestions.

Probably a bad strut or spring on that side. No, they aren't adjustable

 

Sorry to revive such a very old thread. Wondering if any other reason for this issue has arisen over the years. My low mileage 06 has this same low ride height issue on the same side (LR). I replaced all 4 shocks (but not the springs) after reading that the gas shocks do contribute to ride height, which is something i would not have believed until i witnessed it myself. The whole car did indeed sit higher afterward, but the discrepancy at the rear remains.
So, is general consensus that i have a weak LR spring or something else ?

 

It could be that the suspension is preloaded on one side where somebody loosened it and then tightened it in the extended position. This preloads the bushings and keeps that side from dropping. The opposite is true too. If you jack the suspension up with the arm bushing bolts loosened and then tighten them in the jacked up position they’ll be preloaded in the opposite direction and then will sit lower.

So for most people the suspension arm bushing joints should be retightened with the suspension jacked up to around the normal ride height position. If you don’t have a floor lift and are doing at home one wheel/suspension point at a time then the swaybar end link connection needs to be taken loose on one side before starting and then reconnected after both sets of suspension arms on the that axle are completed. In reality you can use that technique to alter the ride height some as well. When I raced the RX8 in the Factory Stock class I would use that to make the car lower or to add/remove rake between the front vs rear ride height.

 

Hello, I have a similar problem.
I own a 2008 RX8 with 75000miles.
At 65000 miles I change my suspension with a new one. Koni with Eibach springs.
My problem is that the rear side is lower than the front.
I have change the front bump stops but not the rear.
Could that be the problem?

 

Yes. Also were the shocks for the correct year of car? The rear spring perch height changed in 2009, so make sure you have the right part numbers for a 2008.

 

Thank you . I ll check that. 👍👍

 

and also if the suspension was properly pre-loaded before tightening the bolts down

no, the rear bump stops won’t cause a low rear ride height issue

 

If you have a fairly level surface, you can put the rear of the car in the air to a common height for both sides. For example, one side gets a pair of jack stands (2nd one "just in case") and then adjust the floor jack on the other side of the car to get a consistent chassis height. Then measure the droop of the two tires off the ground. If there's preload or some binding in the suspension, it should be pretty obvious, pretty quickly, with no disassembly required.

Hope it helps anyone in a similar "bind" (bad pun, sorry).

 

So I checked that. Everything is ok.
I measured the height too. From the center of the rim to the fender were 38 cm at the front but at the rear were 36,5 cm !

 

We checked that too. My mechanic insists that is the rear bump stops. I don't think so.
I m so confused because the height of the rear both sides were exactly the same 36.5 cm.
And the front sides are both 38 cm..
