Turned front torsion but won't get low?

[atufte]

Lowered my 912 today, but after reindexing the front torsion, i'm left with more questions, why won't it go down to the adjusting screw again? (I turned it about 4 notches) and i have seen a lot of 911/912's way lower than this...




This is the ride height at the moment... (want to go 1" lower)





Thanks in advance for any help on this issue...

Your A arm bushing is jam front and rear or by pict your car is pretty low 24 inches you are sitting on chock damper.

Thanks, but why do i get downwards travel/movement when i push the front down, should'nt it be stuck if it was bottomed out on the damper/shock? (How can i get the A arm loose if it's stuck, by driving on a bumpy road?) Thanks again. Alex

I've never heard of the need to re-index the front torsion bars to lower. The ride height screw took mine down to 23 1/4 (front, ground to fender lip)with 55 series tires. It must be sitting on something. Your photo looks like you have 55/60 series tires.

Maybe indexed the wrong direction if that is possible?

You need to move the car, drive it to settle the height of the front, after raising or lowering it.

Next, did you install a bump steer kit to level out the steering? If you didn't, lowering it below the Euro requirement height will cause problems with the steering.

Next, you are going to have a very rough ride and will be bottoming out with the very short strut movement. This might also require excessive strut wear and require earlier replacement.

Lastly, unless you are going to use it as a track/autox only car. you maybe scraping every little bump and trash in the road and driveways.

These are some of the possible problems that others have had in the pass with real low Porsches.

I took a drive with the car today, and no doubt I have bottomed out all my shocks... and the drive was horrible...way worse than any slammed VW and i have had a few... so i went with a compromise and raised it 1 notch in the back and added some height in the front for some shock travel, the car is now ok to drive again... But i'm planning to swop the shocks on all 4 wheels to some shorter (and newer) do you guys have some suggestions for me? Thanks for all the feedback on this topic thus far....

You still will need to use a bump steer kit.

You will have to find a brand; that has the right type, that will fit the strut tubes. It will make the difference if your struts are Koni's or Boge

Lowering doesn't require shorter shocks.
Adjust ride height in the front and the rear use/install adjustable spring plates or reindex rear torsion bars. That's all I did and my car sits as low as you should want to go. Any lower will put the car virtually on the road. I can't even go over some speed bumps without scraping my rear sway bar drop link bushings.









These are 55 series tires. 60 would be better as it would lift the car a little more off the ground but fill the wheel wells better. I also do not have a bump steer kit and my suspension does not bottom out. Any lower is asking for trouble IMHO.
Any lower than this is

I have already bought a Bumpsteer Kit, thanks...

Mine is slightly lower than this an I still have plenty of travel on the shocks, my only problem now is bump steer... And i just bought a bump steer kit...

But i still want new shocks, the originals are worn out...

Thanks anyway

Alex,
If you use a gas filled shock (Bilstein) it will raise the car a bit.
Final lowering is usually done after the installation of new shocks.

Like TONY said .And you have to full your gas tank .
