I am lucky to be posting this. I am supposed to get an alignment done tomorrow and I need the numbers? and what all. i am barely getting a wireless connection, so please save the "do a search" please. Its for my 86.5, and its on a Hunter machine. Thanks.

dont let them lift the car and let the suspension decompress - particularly on the front. most shops want to do this first to do a basic check on things. tell them you will sign a disclaimer if necessary but you dont want them to lift the car and take the weight off the wheels. this is imperative.

you can deviate from factory specs, try setting zero toe on the front and maxing out the castor here - this improves stability and reduces tramlining.

camber should be set according to how much of a demon you are in corners - more if you have a lot of twisty roads near by or go to the track often.

also if you are tracking the car, get the alinement with a half tank of gas vs the full tank normaly reccomended.

The machine will likely have the data in it. If they want to lift the front to spin the wheels to initialize the wheel sensors, have them roll the car back on the rack, instead.

See the ** footnote on the spec sheet. '86.5 can use '91-'95 specs.

...

I'm going back again, today, too! I wanted to double check the specs with my new 18" rims a few days ago. Got it all loaded up on the rack, and one of the rear toe eccentric bolts was fused, and all the threads were bad. Very interesting to drive around with variable rear toe, I tell ya!

Have them get as close as possible to the center of the toe specs. Caster is often impossible to get below 4.5 degrees. Camber may not go below 1 degree. That's fine. Just make sure all the parameters are equal side-to-side (no or very minimal cross camber, caster and toe). Many alignment shops check the alignment, and will accept anything in the +/- range.

I had mine done last week with this spec sheet coming out of the machine (hunter) its the same spec sheet I've seen many times before from Hunter machines all across the country

why is the total toe .25 on the rear when Ive seen many a spec for .5 degree total toe on the rear for our 928s????????

As others have said, the Hunter machine will have the correct data preloaded.

Make sure it is a modern Hunter machine that does not require jacking the car off the wheels to set the laser sights.

Well It happens to be a friend of mine so I trust him. His machine is a Hunter but it does not have laser sights its the old clamp on style. He said he can tape the clamps to protect the wheel finish. I was looking over his shoulder when he brought up the 928 it lists 77-80 and 91-95. I told him to use the later is this correct? even though I printed off and gave him the WS manual (thanks Andrew). I have this scheduled for tommorow.

Bill Ball

Right. The only change was the caster, which you may not be able to get below 4 degrees anyway. Caster provides straight-line stability and self-centering steering.

icsmike

Ok, thanks all.

PorKen

On my friend's lift, there was only just enough room to init the sensors by rolling the car all the way forward, then rolling back.

Good thing it's a friend. He doesn't mind rolling it, and spending the extra time to get it right.

bump! I just pulled my alignment from 02. .5 degrees was the max limit of the rear toe. now, ive seen .25 degrees on two alignment print outs as max.

whats up?

I wonder how much variation the Weissach axle makes in rear toe depending on ride height.....more so on lowered 928's than stock height ones...but a lowered car should have quite a bit more toe than a stock height one?

Does anyone know how much toe the weissach axle adds under compression?

Bill Ball

I don't know where 0.5 degree comes from. Racing specs can be a lot different than street. Take a look at these specs and comments for the 928 Cup.
