I have the Bilstein PSS coilovers on my AP1, and I've had them for almost 2 years now. I adjusted my ride height yesterday, and came across an issue that I remembered from initially installing them.

Both front fenders are at the same height from the ground, and the center bore. However, the driver side coilover is at the bottom of the threads (as low as can go), while the passenger side is an inch higher on the threads. Is this a normal problem? I would say normal if it was a quarter inch or so, but not an inch. The springs are properly seated, it drives fine, makes zero noises. Any ideas?

 

Anybody? Bueller?

 

Bad spring.
Someone else had that same problem a while back.

 

Thanks for the info. Do you know if Bilstein was good about replacing the part? I'd like to replace it, but not have to get another alignment after replacing the spring.

 

You have to pull the upper control arm off the chassis so it's a tough call. I don't think much will change again assuming ride height stays the same.

Ideally two new springs would be nice but getting one from them would be good enough. I'm not sure how the actual deal went down but working with Bilstein in the past has been painless for me unlike JIC.

 

PM lilazngrl4o8 - she had a sagging issue with one of her PSS9 springs up front before and had it replaced by Bilstein. I bought her coilovers a few weeks ago and I'm not having any issues
