Bilstein HD raised 945

[vcolper]

I just installed a set of Bilstein HD's (used) on my 945T and it look like a jeep cherokee. These shocks have raised the wagon about 1/2" to 3/4".
Is this normal?

What should the normal height be?

Thanks,
Vic

There a stiff strut but nothing that will lift your car. Is the suspension super stiff now? It's possible they have water in them and the unit is hydrolocking

"Not super stiff". It rides a little harder but not bad at all. No leaks are visible. How would water get in?

The Hd units are inverted. So the yellow body you slipped into the strut tube is hollow with the skinny shock shaft were all used to seeing. Water leaks past the gland nut and internal wiper filling the yellow cartridge with water so as the strut compresses it slams into the water and stops. Mine did this and drilling a hole near the bottom of the tube/strut itself allows it to drain

The gas pressure in the bilstein HD can raise the car on installation, especially if you have soft springs. If you have stiffer springs the car isn't susceptible to ride height changes from the gas pressure the shocks have.

Good tip, especially for those blessed with about 9 months of rain a year.

Yep I have seen this before, the car rode like complete ****... because the bottom of the strut was full of water.
