When my subframes were welded. Many years ago. The tires weren't supported. When I took it off the lift. The car immediately felt funny. I've driven it every since. However I'm notnsure when the intolerable high speed vibrations started. I've changed tires. And rims and both several times. It's still there. I added lca and then went to double polystyrene. Still there. I had tokicos then went to a Strabo koni set up. I picked up .3 in the quarter. But still there. Ive checked the drive shaft and changed the tranny mount. Still there. I have a dammed m6. I'm wondering if the frame somehow is jacked and not allowing the wheels to sit evenly which causes my low trap speed and serious vibration. The freakin car feels like its going to shake apart at high speeds. I think i could actually spped up if i didnt have the vibration.

Subframes connectors are supposed to be installed with the suspension loaded. Problem solved

I found subframe connectors lessened some of my vibrations from the engine. Just installed on friday, car feels "stiff" again like when I first got it.

Just went looked at the lift. The suspension was loaded. It must have had a tilt though because I remember something making me uncomfortable

if you weld in sfc's with the tires off the ground its the same as hog tieing a human. prob would cut them off and re-weld them

Take it to a body shop and have them check the frame. What size wheels and tires are you running?
