Ok, gonna make this quick because its almost 4am and I want to go to bed.
Took me about 6 hours of fab'n, and welding. I first installed the connectors, and then added smaller rocker panel supports due to the fact that on unibody cars, the rocker panels/pinch welds are a MAJOR body support for the car. On my 88 Notch(mustang) I installed 1 1/2" x 1/8" square steel tubing subframe connectors, but I didn't want to go as big on my Mark because I didn't have the room. I also made a rear subframe brace while I was at it, and plan on doing the K-member braces also(I did the connectors B4 installing my headers, so I didn't want to bother welding anything in front yet).
NOW the body FLEX test..........so I jacked my car up from the passenger side SF connector to see how bad the door would be out of alignment....check it out
Almost 4' high...
Shows the angle of the drivers side, lol! Notice how the entire front of the car slid over and bunched up the carpet
This shows the door gap, the door open with little effort and is maybe 1/4" off. Not too shabby
These help SOOO much with speed bumps and dips in the road because before it was my K-member that took the abuse and the little pinch weld on my drivers side cat that got shaved off flat.
This picture shows the clearance with my exhaust. The cutouts would scrape going over speed bumps, but the billet alluminum finally flattened out and now its just the steel flanges that scrape.
