WELD your Subframe Connectors!

**9t8z28** · 02-27-2011, 06:10 AM

I have had (BOLT ON) 3 point UMI Subframe connectors on my car since August 2007. They definitely made a difference. They tightened the whole car up and I noticed less squeaks and rattles (especially the T-tops). I also noticed that when I would put the car on a 2 post lift, the doors would open and close much easier vs. before they felt like they were miss aligned.

Last night I welded the subrame connectors on and took it for a drive down some rough roads. I heard no rattles from the T-tops and no squeaks. It was a total night and day difference. I can now put the car up on the lift and the doors will open and close the same as they would if the car was on all 4 wheels.

Just make sure you guys weld the subframe connectors on while the suspension is loaded (car on all 4 wheel).

There will not be any signs of movement. I didn't notice any rub marks where the braces contacted the chassis. Like I said, most peeps can't imagine the difference between bolted on and welded.

Why would you need to take them off anyway?

i took them off when i drilled out the front bolt hole for the LCAs to 1/2............the UMI SFC holes were already 1/2 as i found out......but still it was good that i could remove them

No question that welding them would add to the structural integrity. I just don't want to mess up the pretty underside of our car.

I hear ya. I guess that I am addicted to the, no squeaks solid chassis that now handles like is got a full frame. The car feels totally solid and now I can say that having them bolted on allowed a lot of flex.

you can't beat the handling and feeling of a solid chassis car. I love my SFC as well.

I just have the 2-pts so mine never get in the way

Never been in a car with bolt-on SFCs so I don't know how that feels, but I know with my current set-up, my car feels 100% solid.

3 point subframe connectors do not get in the way of anything. There are very few brands out there that might not be designed as good as the UMI or BMR. I have run some pretty crazy exhaust systems on my car and not one time was the SFC in the way.
