Another Ride Height/Corner Balance Question

RichMink76 · 07-23-2012, 11:38 AM

I had my car aligned and corner balanced and the ride height is higher on the right side of the car than the left (about .5 inchs). It also has more rake than I would like to have. When I took it to the shop I had the ride height set to where I was hoping they could keep it close to.

My question is are my torsion bars indexed incorrectly and can I solve my ride height issues by re-indexing.

The car seems to drive great, it's just one of those things that I would like to solve.

Any help would be appreciated.

Left to right ride hight is normal since they have to offset your weight in the car. .5 inch sounds like a lot however.

If you change anything with the ride height, it will no longer be balanced.

Did they give you a set up sheet with all your numbers (corner height, weight, toe, etc.)? If so, post it.

If balanced for ride ht and corner wt, with you out of the car, the drivers side should be higher, not the right side. With you in the car...level

Porsche has a specification that allows a 5mm difference in height in the front and 8mm difference in height in the rear. Admittedly, this can sometimes be hard to achieve. It sounds like your height is off a little bit. You might mention it to the shop, or list the numbers they ended up with on the alignment.

I thought raising a corner adds weight? Or do I have that backwards?

It would seem that raising a corner higher would put more load on that corner. That is what leads me to believe I have them indexed incorrectly. If I re-index them so it lowers that corner (or side) it would still have the same load just lower. That is my thought process anyway.

Am I off base here?

For added info I have 23/31 torsions and Sway-a-way adjustable springplates in the rear. That makes ride hight easy to adjust.

Thanks for your input all.

You had it corner balanced without sitting in it?

To confirm others suspicions, raising a corner puts more weight on that corner and the corner opposite.

Re-indexing won't do what your thinking, as it will change the load the corner is seeing. Reindexing is just a larger adjustment than the adjustment bolt that you would use to adjust your corner weights.

If you had your LF jacked really high, putting a ton of weight on the LF and RR (the car would be teetering between these two corners), then changed your ride height on the LF by reindexing, you'd be changing the pressure that corner is seeing

how are you measuring ride height? fender lip to ground or the center of the wheel to the center of the pivot of the Tbars?

like he said above. indexing is a rough setting, but, if one side was off, that may be why the rear was raised.
what do the adjustments look like in the rear? are both close to being the same or are they at opposite extremes. IE, one side is adjusted to lower and the the other side adjusted at the raise extreme.
