DIY Alignment? - Gyraline

[teejnut]

Got to refreshing the front end suspension with new UCAs and LCAs. Planned to have Gyraline in hand just for this occasion.

Setup on alignment plates on front axle and leveling ramps in the rear.

Gyraline has been updated (v2.22.07) since I've last used it and seems pretty polished. Looks like they acknowledge Android phones are not useful for alignment and are coming out with a Gyraline G2 with external precision sensors to support Android (at a much higher price point).

Apologies as I was in a rush and didn't get before and after specs as I realized later screen saves in app weren't working. Also adjusting alignment might be more difficult than most want to tackle as it's a fine balance of caster, camber, and toe. In a maxed out config like mine, I can eek out just enough in every parameter, but would be hard for someone starting from scratch to learn the app, learning the mechanics and art of alignment, and what to aim for in a 200-series.

That said, the app worked great for my needs. Took about 2 hours between 4 adjustment and measurements to get where I wanted to be. Then put her on the road for a 300 mile off-road trip. Nailed the alignment in one go it performed flawlessly to my amusement.

Caster on both front wheels measured 2.8 (which is fine on 37s as it's more about the length of mechanical trail)
Camber measured
-0.05 on left wheel
-0.04 on right wheel

Toe

EDIT: Adding more detail. Toe is the most important parameter and probably the hardest. Difficultly is that it's hard to establish a datum (reference point) that points truly straight and center relative to the vehicle. Versus camber and caster where it has absolute level as a datum (provided the ground is level). The app is best at comparing a previous surface to the next surface. Additional surfaces create tolerance stackup and drift.

There's two modes - body align (first pic below), and thrust align (second pic). Both are useful but helps to understand they use different references.

Which alignment plates and level did you get? Happy with it? Use the same setup for the P car?

If I ever get a large enough space for a proper garage I’m throwing plenty of dead presidents at a lift, a good used hunter machine, and some good used tire mounting and balancing equipment.

Someday!

A lift is worth so much more than dollar bills. Safely and quickly putting your work exactly where you need it to be is so satisfying. Not rolling and scooting around on the hard ground, no room to move, getting dirty, dropping tools, dropping parts, can’t reach a tool, can’t get leverage, stray dog licking your sweaty inner thigh on a hot summer evening. Helps keep you from looking (and feeling) like a 28 Days Later zombie when you finally get up off the ground and hobble into the house.

You're not doing a good job in selling the lift with some of this description.

Haven't done the p car yet but that's going to be all of January for a new clutch brakes, spark plugs intercoolers...

I got these plates which should work fine.

Interesting, the Porsche dealer nails the alignment every time. As they should with how much they charge.

I would think Porsche may still be able to pay and retain skilled mechanics so your 911 series should be in decent hands with them.
