Hi guys,

I'm a bit desperate here, hoping somebody may have come across this issue....

I got my Stang' about a month ago, and instantly wanted to get some suspension work done. Alas, last week I ordered a set of KW V3's, and had them installed this afternoon.

So, though the feel of the suspension is outstanding, I'm concerned about a strange noise I'm now getting.

It sort of sounds like a heat shielf making light contact with the rotor. Kind of a hissing sound. It's definitely wheel speed actuated; definitely not braking or engine speed and as far as I can tell it's coming from both sides.

I put it on the lift earlier today and couldn't see anything that looks out of wack at all. It's not the heat shields.

My plan for the moment is to let the new suspension settle in a bit and take it for an alignment in a week and pray. Thing is, this is coming from the rear, and I toyed around with the pan hard bar to see if I could get anything to change at all and couldn't so I'm worried this is not going to help. I'd honestly be surprised.

If anybody has any ideas whatsoever I would really really appreciate it.

I'm going to take a video tomorrow and hopefully the sound shows up on it so I can show everyone.

I have to get this figured out. It's not incredibly loud, but it's a noise that shouldn't be there and that alone is enough to drive me batty.

Subscribed! Does the noise sound like it pulsates? Obviously with speed it would seem like one constant sound but at lower speeds does it "hiss..stop..hiss..stop". Usually when the sound does this it means you either A have warped rotors or B the brakes are not mounted correctly causing an irregular contact on the pad/rotor.

Thanks for the response! I appreciate it.

It's definitely not the brakes. I've had an almost identical sound from bad brakes before, but not this time. Pressing on the brakes has absolutely no bearing on the noise whatsoever. Also, I had NEVER heard this prior to the coilover install, and after, it's constant.

I feel like it's axle related or something. I don't have much negative camber at all but it almost seems like when the rear end was lowered it started dragging somewhere. Like something isn't straight or something.

Rear axle alignment is very important after lowering the car. I installed not just the adjustable panhard bar but also adjustable lower control arms as well to perfectly center my rear axle and help get my overall alignment perfect.

A few things I can think of that would produce the sound you describe is the parking brake cable where it snakes to the rear caliper, the main brake line against the tire(if you might have forgotten to bolt it back to the body), or the fenderliner against the tire.

I had the latter as my right tire came too far forward going over bumps. For you might vote goes to the parking brake cable.

Yeah I feel ya on the alignment.

I think for now the plan is to just let the springs settle in a bit, align it next week, and hope that does it.
