With all new rear adjustable control arms, can the kinematic toe be done without the motorsports tool that hangs on the calipers? Had one attempt at an alignment and I'm sure they didn't get it. I'm a ways away from the shops that have expertise with 993's and trying to develope options.
Thanks in advance for any help

You need that factory (or the Autometric version) tool to accurately measure KT.

No other way to get this right without protractors and the ability to calibrate them.

I too am in the same position (Porsche hell with no one around for hours worth a damn!). Kin is "bump steer", work the rear suspension while aligning and look for positive (or negative) toe while under load. It can be done, and may not be absolutely perfect, but..........
I tracked my 993 like that and did just fine. The guy that did my alignment is no where to be found these days so I can't answer what exactly he did......

There are people in SoCal who do this without the tool, but they are experienced and know what they are doing.

Where in Central Ca are you located? There are several great shops near SJ.

Modesto area. I would need to be at the shop first thing and wait for the work to be done. So gotta find someone skilled, accommodating and cheap :-)

Pick two of those, getting all three might be tough.

Dave Graff at Borelli Motor Sports in San Jose is great and they are pretty accommodating. I think I paid around $300 which is about the going rate in the bay area.

Thanks P, I knew I was wishing for too much there :-)

We've all left the business, since we can make real money doing something else. With 5% of the headache............

Go see Gordon @ Autometrics in Charleston and he can do a very good alignment on 993's.

Is this adjustment independent of toe and camber or do they all change when an adjustment is made?

If you had all monoballs in the rear (e.g. no kinematic effect due to no deflecting rubber), than would you still need to set K-toe using the tool? Why could you not just set a reasonable caster value using a laser alignment machine? Does the multilink suspension travel under load in such a way that static caster is not a good indicator of the dynamic behavior of the suspension?

If not, why not just use the tool a single time and note what the actual caster value is when using the tool to set the proper measurment, and then any time you have to do an alignment, just use your previously noted caster value and you'll never need the tool again.

Does this sound crazy? Just food for though

They all affect each other
You go in order
1) ride height & corner balance all around
2)Rear axle first a) toe link 2 eccentric A b)camber link3 eccentric B 3)Kinematic bump toe link 4 eccentric C
3) front axle toe, camber , caster

for track use I'd recommend using turnbuckle links rather that the eccentrics

Bill Verburg

You still set rear caster to +3° 00' to +3° 30' rear, whenever an link is adjusted it changes the others

The main reason I have to get it done is because I replaced the 3 arms on each side with adj. arms. So I am starting from scratch for the most part. There is still a small amount of rubber (inner joints of lower control arm). Once I get it setcorrectly I should not need to do it again (hopefully).
