Help！gentle/faint popping noise after lowered

[Kcc-Breeze]

Hello so few days ago I lowered my brz with a set of Eibach profit. Everything went smoothly and the spring ride great!
No sound nor noise when driving normally or on highway.
But whenever I’m trying to park, and applied the brake I can hear a popping noise from the front of my car not sure if it’s from the driver or passenger side.

I’m pretty sure it’s from the suspension mod i did but just can’t pin point down to where the sound would be coming from. Car only has 2500km highly doubt it’s from other suspension components. Nor brakes either because I can only hear the noise when the weight of the vehicle shift suddenly (brake hard when at slow speed)

I did torqued down every single bolts as well including my spc camber bolts. Did the alignment as well already. ( there was a squeaky noise when braking at slow speed in the front before alignment, sprayed lubes around suspension joints and squeak noise went away)

Expect I did not torque the top mount strut nut (couldn’t find a way to torque it so I just gunned it tight but not too tight when the wheels are on the ground)

Could the popping noise be coming from strut nut being too tight? Or too lose? How do u guys torque the struts nut?

Thanks !!!!!

When I installed my coils, they made a faint pinging noise for a couple of weeks. So maybe wait a bit and let things bed in?

Usually loose end link connections

But I torqued my front endlink to the correct torque tho? Is it because I had coilovers before but tightened too tight before (didint torque back then I just gunned it on) now even if to torque spec it’s still lose?

Check it anyways. Suspension manufacturers always say to retorque bolts after a couple of heat cycles since heat can loosen it a bit.

Is the noise happening as you turn the steering wheel? If so, it's probably the spring binding slightly. I'd lift up the front of the car and turn the wheels back and forth to see if you can hear where it's coming from better.

nope , steering wheel straight its just when I at a very low speed like 3km/hr or so and hard brake then I hear a knock sound from the front

End links or pad knocking slightly.

Yes. The pads can move around slightly in the caliper, and will sometimes make a faint knock if they move on initial brake application.


Do you have the brembos?

Agree with end link, thats where my popping came from post-install.

What coilovers did you have before? A number of kits come supplied with shorter endlinks to compensate for a located upper mounting tab. If this was the case with your previous coilovers make sure you'e swapped back to stock / stock length links.
