How to check ride height/results
I checked the ride height now that the suspension is settled and aligned .
Spec for the car is F 106mm (+-10mm =96-116) R 133 (+-10mm=123-143)
I measured it twice once with 160lbs of weights in the driver’s seat . Once without , both with a full tank of gas.
The max allowable difference is 5mm side to side. I’m glad its right on because otherwise I know I would be obsessing on it. Redoing corner balance and ride height plus alignment takes 5-9hrs and it’s a pain in the ***. carl
With weight no weight
RR 132.57 RR132.48
LR 130.00 LR 132.03
-2.57mm -.45mm
RF 110.87 RF 112.89
LF 109.57 LF 113.63
-.70mm -.74mm

You do your own corner balancing? That's awesome if you do.

Seems like a lot of people are saying the following Camber/Toe is a relatively solid set up without messing with Toe Links. Would love to know if anyone has spent much time dialing in ride heights for bumpy versus smooth tracks (high compression vs. low) or AutoX. What is too low? Is stock ideal? is lower better?
Front Camber: -2.5
Front Toe: 0 to .1 out per side
Front Ride Height: ???
Bar Full Soft?
Rear Camber: -1.8
Rear Toe: .1 to .2 in per side
Rear Ride Height: ???
Bar Full Stiff?
Front Camber: -2.5
Front Toe: 0 to .1 out per side
Front Ride Height: ???
Bar Full Soft?
Rear Camber: -1.8
Rear Toe: .1 to .2 in per side
Rear Ride Height: ???
Bar Full Stiff?

You can also use Porsche online technical service, which is a paid service and can download the documents you need. Here is the link if you are not familiar with it. Mark

Here are the two measuring points . carl
Compress (push down) vehicle at front and rear axles twice or three times and allow it to spring back freely.
Measure from road contact surface to measuring point on the body.
A quick check can be performed by measuring from the lower edge of the wing to the centre of the wheel.
Rear-axle height: Measure from wheel contact surface to lower
edge of diagonal brace (between the ribs) at wishbone fastening

And another reason people are messing with rear toe links is to keep the rear camber only +0.5 relative to front, so if you want -2.5 in the front you may want to do what it takes to add more to the rear.
