I have an 86 951. I took a measuring tape and measured from the top of the wheel well of the front tires to the floor, and my right side is just a tad lower. the po lowered the car and I don't know what he put in, and I know nothing about suspension.....how do I even begin looking into solving this problem?

is it still higher when you sit on the drivers side? Sounds like it should be perfect...

Dan's suggest is a good one to try first. But even if it's off by 1/8", that's not a lot...

also- measure from the bottom of the rocker or door- the wheel wells arent always the same height.

hows the tire pressure?

1/8 is nothing...

that makes me feel better. ill do some more measuring.

Get it corner balanced for your weight too if you're going down to 1/8th...

Is your emergency brake engaged? This can make the left side sit higher.

maybe the PO just had a fat wife?

1/8" is not uncommon after corner balancing a car, done right.

I just noticed this as well last week!

Is it supposed to be higher unladen? And balanced with a driver inside? If so, I love that. But I do need an alignment FWIW. Just checked tire pressures 2 weeks ago.

Corner balancing? How do you corner balance a stock car? There is no height adjustment at the front and very little at the rear to perform a weighted balance.

I had my 86 track car corner balanced but it has coilovers all round. 1/2 tank of gas, tire pressures normal, driver seated and I'll tell you the measurements were all off from stock when it was balanced. When you balance by weight you cannot expect the bodywork to measure up evenly, it won't.

Back to the OP's question. Measuring to the fenders is not accurate, try measuring to the points in the manual, that is the bottom of the rocker panel at the front and rear edge of the doors. Adjust rear eccentric to level rear to match the front or have a slight front rake. That's about all you can do on a stock car.

Anyway there is really no point in corner balancing a street car even if you could easily do it. You put "stuff" in a street car like luggage, passengers, etc. it's a variable environment everyday.

There is in fact a fair bit of weight movement that can be done with the rear ride height adjustments. Even with the adjustable fronts on my own car, I don't use front adjustment to distribute weight, only to set desired and matched ride height. Unless your car is twisted, I believe you should be able to distribute properly using only the read height eccentrics.

Another thought is that it is worth rechecking weights after alignment, since everything interacts and a screwy alignment will affect distribution.

Kevin is on the money here - that's why Porsche put those adjusters on the rear torsion bar slip plates - to corner balance the car. (Not to "lower the rear" like everyone does.)

Some shops will put weight in the driver's seat when they corner balance, and this could cause the 1/8" difference (like Dan suggested).

Also, the proper way to measure ride height is from a level floor to the heads of the caster mount block bolts for the front; and from a level floor to the bottom of the torsion bar end-cap tubes.
