How to lower 912 front suspension?
 
The answer may be obvious but I'm not seeing it. I know how to lower the rear but how to lower the front. I'm thinking no lower than an inch. Thanks.

hello

the front is fairly easy to lower there is a grub screw that pushes on a torsion key that you can back down to lower the front. if your car is level and drives straight i would mark and count rotations so you can go back and keep things level. if you search in the 911 tech section you will find quite a bit of traffic on this subject. you will need to have a alignment and final adjustments after you lower the car.

have fun!!

along with significant lowering, consider adjusting the steering rack height as well, to prevent wheel kick back due to altered geometry of the suspension parts. You can buy inexpensive kits to do this such as the Weltmeister Bump Steer Kit

Something's wrong
 
What does it mean if I backed off the bolts and the front does not lower? There is just a gap now between the bold and the torsion key.

Here's a stupid question.... is the car on the ground on it's wheels? If it's jacked up there will be a gap.

Wheels are on and it is off the jack, still a gap.

Did you bounce the front to settle it? Rubber bushings require a drive around the block to get the car settled before assesing the amount of drop achieved.

I did bounce on it. Maybe I'll give it more time.

Thanks.

Did it settle down?

If not it's possible that the suspensions has been apart in the past and assembled incorrectly - at least for your desired ride height...

Similar to the way the rear adjuster plates go on the end of the torsion bars so do the 'change levers' (#14) on the front. The adjuster screw (#15) is what you have backed out.

Here's mine, front wheel opening is 25.25" and the rear is 24.75". Tires are 205/60-15's all around.

Hey all,

You are missing (1) step. The most important.
First thing that should be done is loosen bolt #2 shown in the diagram.
This bolt not only bolts the crossmember to the body,
it also pinches on bushing #8 to secure it from rotating.
On my car it toke a little extra bouncing to loosen the pinch on the bushing.
When you get the height where you want it, then retighten bolt #2.
As the others have said, a bump steer kit and realignment will be necessary.

PS I wouldn't go 'too low', those steep driveways are a ***** on your front spoiler...
