Does anyone have detailed instructions for doing an "at home" driveway alignment? (with pictures would be nice)

Rear Shims are no problem. I can get some laser cut in different thicknesses.


(Local independent Porsche shop estimates $400 for a proper alignment.)

I would think a well written how-to with photos would make an automatic classic thread.

Crap I just did one on my car Monday evening.

From rear shims to Front camber caster
front and rear toe.

I get gun shy posting pics of my Red Neck procedures as it is surely not up to the standards some here are accustomed to.

But the results are hardly questionable. goes straight turns in quickly and heats the tires evenly across the face.

I have an article on the Pelican site and it has conversions for fractions of an inch to degrees camber and toe in/out for 15 inch wheels included.

Read these. You can make "strings" with conduit and attach to the car by the license plate screws. You can buy a caster/camber tool off ebay. You wil spend a lot less and have a set-up you can use again. Email me if you want more info.

Oh - turnplates can be 2 sections of slippery masonite placed "face-to-face"

Is toe measured from the wheel or the tire?

It seems 1/8" total toe in at the front of the tire would be slightly less at the front of the rim.

RIM
Because John's figures are off of a 15" circle.
I would try 1/16" toe in on each wheel for a total of 1/8" toe in.

I did 1/32 toe out the other day and it's not quite enough as the car kinda wanders. More toe out will give me quicker turn in low speed cone dodging.

Porsche specifies Toe in "degrees". Measure from the rim. You will have to calculate degrees as it depends on the "measured" diameter of the rim.

Can use a magnetic angle finder mounted directly to the strut body to set caster?

if you use the string method, you would need at least 3 people when you adjust the front; one to hold the steering wheel inside the car, one to adjust the tow underneath the car, and one to tell you the measurements from the wheel to the string.


i align 911's for post races.

Yes. My rule of thumb is to set the top strut mount as far back as possible for the street, for stability. Set it forward for faster turn in or less camber. If you read the fine print in the article, it is for initial steup or in case of a off at the races and should not be used in place of a professional shop alignment for long term use.
