HPM trmec crossmember anyone using it?

[rednotch]

I swapped one in my car to eplace my modified stock one that was cracking in the middle from too much abuse. Just swapping the crossmember caused a nasty vibration at 4-5k rpm, anyone else have this problem?

I'm thinking it was a pre existing vibration that just amplified since the HPM peice has no busshings where it mounts to the body.

Driveshaft maybe? Its not uncommon if you have gears and use the factory driveshaft you notice a vibration. A lot of people switch to the aluminium one to lesson or get rid of it. Just a thought.

You're going to feel a lot more vibration without those bushings installed since the crossmember mounts directly to the chassis.

not the driveshaft swaped in a known good one and my u-joints are fine. this vibration is not normal I;ve driven many cars with solid mounts, the vibration is also not steady but rpm specific.
