i just finished putting in my subframe connectors...halfway done with the roll bar installation. also found, on inspection of the underside of the vehicle, that i had cracks in the body, one under each door, and one under the rear seat right about in the center. if you have the means, id suggest inspecting your car as well. little cracks in the frame can lead to major problems, especially if youve got some power in the engine.

so we got the cracks welded up, put the subframes on and now it doesnt rattle or creak when i drive over bumps. also a noticeable difference when cornering. much more solid feeling. i deffinately recommend buying them

 

I have a 90 Gt vert. I plan on adding the sub frame connectors. Did you put full length connectors on and what brand did you go with?

 

On my 91 vert I put on non-full length subframes and they helped out tremendously. I would highly suggest them.

 

how long/har was the install of the subframe conectors?

 

i got the full length from maximum motorsports. the most time consuming part of the install was cleaning the underside of the car, scraping off the tar undercoating. my dad is a welder/mechanic by trade, so he was the one who welded everything in, that made it quite easy on my part. id say a full day for home installation, morning to clean and prep, afternoon to weld everything in

 

did you drill out those frame supports(they look like grids) at the corners near each wheel then cut and reweld them to the connectors?

 

we cut a chunk off of the front ones, so that when put back on, it touched the subframe connectors, then welded to them. in the rear, a slot was cut out, and the rivets in the way of the subframe connector were chiseled out of there, then the slot was welded to the subframe above it

 

approx. welding time?

 

well, that could depend on a few things, experience being the number one. my dad did all of the welding, he has been welding for a living for 30+ years (his garage is his shop, and we had any tool required for the job) so while he did that i was cleaning and cutting. you weld each side of each subframe connector approximately 2½, maybe 3 feet(2ft on the front subframe, 1 on the back), with a 1 - 1½ inch gap between each weld. -- the gap is necessary because if the weld were continuous, if a crack were to develop, it would eventually run the entire length of the weld. this way there are multiple breaks in the weld, so if a crack were to develope in one weld it would still be supported and less resistant to breakage
