Noise after installation of frame connectors
 

I had my MM full length frame connectors weld in about 3 weeks ago, and twice I have noticed that when i launch the car, there is a crackling noise through all of 1st gear. Is this normal? Are the frame connectors just pulling the frame together, therefore producing this noise?

I dont think the noise has anything to do with the subs. Can you describe the noise better?

sounds like the connectors were loaded (like pressed into place with a jack) during the install. It'll work out. I wouldn't trip.

It's sort of like a wheel hop noise. I've only heard it twice in 3 weeks so I don't think that anything is wrong. I just think that the frame is not use to being tide together.

Maybe, I never noticed anything after mine were installed.

That happened on my 95 Gt when i had subs welded in, it always did it when i hit second hard at the track, and never went away.
That or it's holding your car together better now and something else is popping since your body doesn't want to twist now.....
