Come on I-lean, driver lean like an s10 Options

[nditiz1]

So after getting the trailing arm rebushed on the drivers side I wanted to check the rake. The rake looks good. I checked for level port to starboard and I got a lean. Almost like the s10 lean when the big dudes drive around on them all the time and the springs get sad. Front is leaning too. So my question is - Will the rear suspension affect the front suspension in regards to balance? I realize if the driver rear is super low it will have some affect on the driver front, but its almost like a 1:1 ration where as I thought the front would not suffer as much.

Oil tank is on the driver side accounting for some of the additional weight. I was not in the car when checking the side to side level.

Rear springs are 100lb 914-6 ones two perches up on both. Front is an SC setup with a front sway bar.

Will new rear springs solve all my problems or do I need to investigate something else like adjust the front driver adjuster also?

At the donuts
Drv F - 4 & 7/8
Drv R - 5 & 7/8
Pass F - 5 & 7/8
Pass R - ~6 - hard to determine as there was console work done on that side and the donut was remounted at an angle (IMG:style_emoticons/default/headbang.gif)

From those numbers it doesn't seem like the rear should have as much variation, but it does. The fender on the Pass R is about 2 in higher than the Drv R. Maybe the guy that put on the flares was careless (IMG:style_emoticons/default/confused24.gif)

The lowest point seems to be the Drv F with 1 inch lower than the pass F and Drv R.
So maybe if I adjust the drv F and get that donut in line with the pass F then I can start to adjust the pass R down one notch to bring it even with the drv R. Is this logic sound? Where you at Phil? (IMG:style_emoticons/default/beerchug.gif)

I'm not a suspension expert, but a 1" difference between the fronts sounds like a lot. I would adjust one or both torsion arms until they are equal (or nearly so-you can account for driver weight). Pretty sure there are threads on here that give all the factory specs for ride height, angles, etc. I would start there.

You could try switching the spring/shock sides and see if that changes things.

and even out the front torsion bar adjustments. Disconnect the front sway bar when you do this.

I blame those springs you sold me Tom (IMG:style_emoticons/default/laugh.gif) j/k

Hey, My car sat level.... But I'm a skinny dude. (IMG:style_emoticons/default/confused24.gif)

[malcolm2]

I need to know more..... Eileen too.

I adjusted my adjustable shocks. Happen to remember this, cause I was under the 914 changing the gear oil last weekend. Right side is set about 5 notches higher than the left. But I still lean a bit.

What is causing it?

[SirAndy]

Check the obvious first, like springs not seated correctly etc. Drive it around the block to make sure the suspension has settled.

Otherwise, you'll need a corner balance. And yes, changing the height on the rear will also affect the front (and vice versa).

Take it to a race shop that knows old Porsche cars and have them corner balance and align the car.

Thanks Andy.

Anyone know who does balancing in Maryland?

And be aware that a corner balance will not yield a perfect symmetry of height from side to side.

Set your approximate desired ride height, then take it in.

Nick, try Taylor Chapman in Sterling across the river from you maybe?

Otherwise consider posting on Dorkiphus (if you haven't already). There's definitely a place in Merrifield / Vienna. Just not sure where close to you in Maryland...

[rick 918-S]

I wouldn't measure to the lip of the flare. They could be off during installation and show measurable difference.

@Rick 918-s is spot on. When determining ride height, you'll want to measure from solid points of the chassis. These cars can have significant variation in them, particularly at the fender once flares have been installed.
On my car, which I had corner balanced at a reputable race shop, the tech specifically called out not to measure at any body line. At level (chassis-wise) I have a 1/4" height difference across my front flares.
And not that I'm the world's best flare installer but if you look at my build, you'll see they were installed pretty accurately in terms of fitting them to the body.

Ya' all are lucky -- some idiot installed my driver front fiberglass flare 3/4" too far REARward. (IMG:style_emoticons/default/av-943.gif)

Totally agree with Chris and Rick -- don't measure ride height to flares!

Yes!

Sort of goes without saying . . . but . . . make sure you're on a level surface. My garage floor is not level. Is yours? Have you actually checked it?

[nditiz1]

In my original post I did measure from the Donuts. Is there a better spot than that I should measure from?

The floor is level to an extent. All garage floors have a built-in slope to ensure water moves away from the back per local code.

Let me play around with the front and rear adjustments and report back.

[Superhawk996]

Doh! (IMG:style_emoticons/default/slap.gif)

Doughnuts would be fine.

Why not use factory manual for front? The problem is that spec is +/- 5mm and you are way beyond that.

Are you checking with full fuel? Fuel tank biases weight toward passenger side by design.

Have you moved battery and/or switched to light weight battery?

[rhodyguy]

When I had my CB/alignment done, weights were put in the driver's seat approximating my poundage.
