depends if you like to get the steering wheel jerked out of your hands if you hit a bump in a curve.
General consenous is to go low enough to get the lower control arms to level with the pavement.
You will have the tie rods pointing a bit at this point and should put in bump spacers which is REALLY easy.
tthen do and aligment and drive it.

There is a point that you cant go any further...the a-arm hits the underside of the unibody...
There is a flange there that you can bend flat to gain another 1/4 of an inch...it would be on the front of the a-arm.

You can have your spindles raised or get the spacers... Spacers are cheaper.

You really don't want to lower the front suspension to the point where the control arms are horizontal, much less pointing up on the outside.

The reason for this is geometry. When you turn a car, the suspension compresses on the outside wheels. When the car rolls, the wheel gains positive camber in relationship to the ground. On the front of a 914 (or 911) the suspension compresses and the arm moves more horizontal in relationship to the car. The ball joint moves both outward and upward, and this increases the negative camber in the outside wheel, thus countering the positive camber induced by the roll. This will keep the contact patch on the tire as large a possible, maximizing the traction.


Now if you start with the control arm horizontal, the compression of the suspension causes the ball joint to move both upward and inward. This adds positive camber, which decreases the contact patch of the tire. That decreases the amount of traction on that wheel.

In the factory manual it recommends that the ride height be set so that the ball joint is lower than the pivot points for the control arm.



So, if you want to lower the suspension to extremes, the only right way to do it is with dropped spindles.

Does anyone make drop spindles for the 914, or are the bug spindles a bolt on option?

Drill out existing welds, then press the spindle off the strut: (IMG:style_emoticons/default/sawzall-smiley.gif) (IMG:style_emoticons/default/smash.gif)

Then weld back together at a higher point ...

Andy, are the 911SC struts built the same way?

this can be done this way only on Bilstein struts . The boge struts have a flare in the strut tube above the spindle that will not allow you do this .racer chris at CFR does have a way to do the boge Struts.

Looks to me like the Boges have no curve in them. Mine are Boges as well and they look exactly like Andy's.

It's not much of a flare but is enough that the spindle mount can't just be slid up the tube. If you mic below then above where the spindle mounts you will see. Tangerine racing cuts and sections the tube to raise the spindle

Here's a couple of links to the Pelican bbs that discusses what ClayPerrine posted and also talks about the Boge struts.

cheers

It looks like the spacers would still be needed with the spindles raised. =o( unless the stearing arm was bent at the same time, like the link that elmonte posted showing the tangerine method.

looks like i'm disagreeing and agreeing all in one post. lol

Yes Steering rack spacers or better yet something like this to fine tune the bump

It looks like the ones modified from tangerineracing do not require the spacers on the control arms, they bend them into possition!

You are correct, my mistake.Not a big fan of the way the spindles are raised or the bent control arms on the Boges . Better to get a set of the Bilsteins, but that would mean new brakes for the 3 1/2 caliper spacing. Don't know if the Bilsteins come in 3 inch
