				IN an effort to lose weight off the race car, I want to cut the SFCs off. However, I use them to jack up the car. After seeing several "pro" teams use a receiver/stab setup off the roll cage, I began fabricating this kind of rig. I used 1" square tubing as the receiver and gusseted the hell out of it to keep deflection to a minimum. I have some 3/4" solid bar stock I was using as the stab. After welding the receiver portion to the cage and mocking up the stab with plenty of gussets, I tested the rig and ... it bent. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/mad.gif) 3/4" solid bar stock bent like a pretzel. And it yielded right at the end of the gusseting. Think of it as a pry bar. I opened the door and placed the jack on the end of the receiver and lifted the car without an issue ... So help me out here ... what can I do to the bar stock I have to increase it's strength or what kind of 3/4" bar stock can I source that will lift 1500lbs? |

				I used small trailer hitch recievers and made a stab out of the insert. Will look for some photos (IMG:http://farm4.static.flickr.com/3188/3059876322_da9d9a4349.jpg) I don't have a clear pic of the passenger side, but you can see a bit of the triangulation in this photo.....I do not attach to the body of the car on EITHER side...except for the tab running down on the back side you can see in the pic....just a flat bar strap. ....no pics of the stab....will have to go out to the trailer and take one.....hold on....
