Height Adjustment & Travel, Why parallel? Options

[Joseph Mills]

My 914 goes to the shop next week for alignment: 1.5 to 2 degrees neg camber front, 2 to 2.5 neg rear with 1/16" toe-out front, 1/16" toe-in rear. Tires are Hoosier A3S03's.

I have found a few posts that seem to indicate that when the A-arms and trailing arms are parallel to the ground, you have maximized your cars height. Is this in fact, correct?

If so, why is this level preferred? If you go below this height is suspension geometry adversely effected? How much wheel travel is left at this point?

Joseph; I'm curious about the numbers you posted because I had my car aligned yesterday by a Porsche only mechanic. He set it at: Front 0 toe and  -2 camber, Rear 1/16" toe-in and -1.3 camber. He said that was all the neg. camber he could get in the rear. These settings are quite a bit different than your going for. Did my guy screw up or is each car going to be different?

Don't forget, the more you lower the rear ride height the more negative camber you get, so if your car sits taller you'll have less negative camber you can dial in. (use adjustable spring plates to change rear ride height)
