Issues with Bilsteins and Camber Plates?

How did you know they were giving out? I've been running the B14s with the SuperPro mounts for ~4k miles and 3 track days and kinda terrified of this happening. Maybe I should swap over to the Vorshlag plates asap?

Starts with a creaking noise, then a rattle/clunk over bumps, and eventually the front end bounced/floated over bumps.

I think it’s a combination of a lot of things for me. I didn’t really start having issues until I ran slicks. I had dozens of track days on the B16s at stock camber, then write a few with the plates, and then after the switch to slicks they were done in short order.

Honestly, NVH and cost was the biggest reason I held off. Cost is an individual thing, but I’ve been pleasantly surprised with the NVH to this point—the SuperPro are the worst of the three I’ve used to this point.

Update: The rebuilders I sent them to (Performance Shock) put them on their dyno and they work as they should. They took the cartridge out of the body and said they couldn't see any obvious signs of damage or failure. They pointed out that the threads at the bottom (where the shock mount sits) are dinged up. This was from the first set of camber plates I used (I swapped the 034s for the Superpros initially because I thought that was the issue). At their urging, I went and looked at the camber plates on the other pair I still have (I hadn't even taken the strut assembly apart) and they show signs of wear as well (the hole in the strut mount is ovaled).

So, it seems that the strut mounts themselves are giving up, which is then damaging the threads on the shock.

And, for what it's worth, we verified the torque was right both the first time I had this issue, and tonight when we pulled the second set apart.

If that's correct, I think I should be able to run these with the Vorschlag plates (or anything with a spherical bearing) because the bearing itself provides more surface area. I'll probably give that a shot in the fall at some point. If that works, I'll run these in the winter and send the Ohlins to get rebuilt.

Also, this would perhaps explain the issues others are having with the strut shaft snapping. If these shuffle back and forth enough, the mount is cutting into the shaft and eventually it would make sense that they could snap.

How are the Ohlins? I’m always interested in these.

They ride better across the range of adjustments. But, the set I bought had 12k on them with one track event. Another track event and 4k later and I think they’re going to need rebuild sooner than later. Which is sort of what I was trying to avoid.

On the track, they didn’t seem much different.

I wonder I'm experiencing the same issues you got. My front end is groaning, clunking, knocking, everything. If it is, this is going to be an expensive lesson for me because I'd just revert back to stock as I don't want to deal with this again.

The issue I had after installing coilovers was that I needed to replace the tie rods because they were making a ton of noise. What happens is the ball/socket on the tie rod wears in the same spot, then when you lower the car (or raise it for that matter) the ball will pop in and out of where it had been wearing.

Aside from having to do the alignment, that’s a cheaper place to start.

I don’t think I’d have had this issue if I stuck with the stock strut mounts and didn’t track the car.
