So I put some 3m windo weld in my front mounts a few weeks ago.

Love it, but the problem is whenever I launch or just quick acceleration from first gear, I get this noise that sounds like plastic hitting each other really fast, almost like a machine gun but a little slower. This only happens from first gear when accelerating, all other gears do not make this noise. Sounds like its coming from near the pedals.

Anyone have this problem before, or how to isolate where this noise is coming from so I can fix it?

 

I don't have this issue.
I would say if it is plastic hitting then you'll be able to tell soon enough where it leaves marks.

Could it be your fans?

 

Thanks man for replaying man, I figured it out.

When I put on the RMR Lip 2, I didn't use any screws or clips to secure it to the bumper under the wheel wells, so when I accererate it causes more vibration/rattling from when it was stock.

 

Good to hear.
