hello all, is it possible to lower the front appx 1 1/2 inches without adding the spacer to the steering rack?
thanks
Robin
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.
i guess i need to put some spacers on my shopping list.
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.
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.
Here's a link

Looks to me like the Boges have no curve in them. Mine are Boges as well and they look exactly like Andy's.
Here's a couple of links to the Pelican bbs that discusses what ClayPerrine posted and also talks about the Boge struts.
cheers

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!
Ok, I am gonna hijack this thread. I bought a 914 a few weeks ago. Actually I have 2 of them. I loosened the screw in the front all the way and let it down. Not low enough. So I removed the strut and cut the rubber bushing inside. STILL not low enough. It rides hard now and I know it's riding on the front strut bushing. Tires are 195/65/15. I am going to go with either 175/55 or 195/45 but this will only add an inch. I could do lowered spindles but it still won't put me where I want to be. I haven't done the rear yet because I can just cut the springs or get coilovers. I've attached a pic of the 914 so you guys can see the ride height AFTER I lowered it. Perhaps there are different size struts. WTF?
Thanks for the compliment. Does anyone else have other opinions on why my 914 is not that low. Lower profile tires would drop and inch and lowered spindles would drop another inch but consider the fact that it's already bottomed out. I'm sure someone else out there has a slammed 914 they could share their thoughts on...
Do you have an antisway bar?
You may also have to remove the adjuster and re-index it to go any lower...that is what I needed to do on every car I lowered.
