Lowered my NSX now I get a knocking noise

[garthed]

I lowered my NSX about a month and a half ago with H&R springs. The installation went fine and everything went back togeather fine. I am now getting a knocking sound when I go over pot holes from the right front. Almost like somthing is lose. I have checked everthing and it all looks good. Do you guys have any ideas. Thanks.

I had a similar problem. It was more of a squeaky knocking noise. If I were to push up and down on the front of the car, it made the noise. Acura of Brookfield re-torqued the front left suspension and all was fine.

Did you put on the silicone/rubber strips that go on the top and bottom of the springs? You need to take them off the OEM springs and put them on the new springs. They are hard to notice because they are black - the same color as the OEM springs. This is the most common cause of knocking sounds after installing new springs.

My bet is that Andie is EXACTLY correct... Install these on your new springs and your sound will magically go away. Use 2 wire ties to hold them on as they will most certainly have lost their 'stick'.

I too put the black plastic on the spring but it did not resolve the noise. Some suggested using convoluted wire loom from Radio Shack. Hope that will work for me.
