Need Help!

[ft911]

I have a Backdraft Racing Cobra with an M3 E36 suspension. I have coil over front shocks that adjust. My dilemma is: I need to get it through NJ state inspection and they hit me on "Front adjustable suspension needs to be locked into place". They are telling me that the front large spring adjuster needs to be locked to keep it from moving on it's own.
Can anyone help me on this? I would appreciate any help!
Thanks

Can you post a pic of the front suspension? If it's like the PSS9 kits, there is a locking plate that handles this function...

Hi Wayne,
I do not have a photo of the M3 suspension, but here is a picture of the standard e36 front suspension. I hope this will help!
Please let me know.

Now I see your confusion - that's not even close to a stock E36 configuration. I see the problem - you're missing a locking plate on the coil over adjustment. The PSS9 kits have this part - I'm not sure what coilover adjustable shock setup you have (it's not stock), but you need another locking collar.

Let's see if some pics help.

Here's the front setup from a stock E36:



And here's a pic of the front PSS9 kit:



What you clearly need is a locking collar that will mesh against your single collar that you currently have. See this close-up pic:



Does this make sense?

Essentially it is double nutting the lower locking collar. Is that right?

Yup, double-nutting is one way it's often done.

Some threaded adjustable spring perches have other methods of locking them. For instance, the Weltmeister kits sold for the 914 rear springs have a set-screw with a plastic nub on the end that acts as a lock.

Yes, that's how the PSS9 kits work.

Welcome back Dave!
