Wedging A Stock ChassisWe all know that wedge is a term used to describe moving weight from tire to tire, much like a horse shifting weight from leg to leg. This is done with spring buckets and wedge bolts that lift or lower the chassis on each respective coil spring, thereby adding or removing weight from the wheel and tire, i.e. weight distribution.
To wedge a stock chassis, we can loosen all the body to the frame mounts. Unless you have a Kansas Jack or some other type of machine, you're going to have to drill some 3/4 inch holes in your concrete floor or use your imagination to secure the chassis to the floor. I prefer drilling and seating anchors slightly below the floor level. When not in use, they can be plugged with a stove bolt with a smooth round head. Once removed, you can fasten sections of 3/8 inch chain to a turnbuckle eye bolt attached to each anchor.
If, for some reason, you want to permanently plug the holes, epoxy and a putty knife is all that is needed. We want to lay out our anchor points in front of the front wheels and behind our rear wheels. This will allow us to hook all four corners of the chassis. Using a floor or bottle jack, we can twist or rake the chassis any way or amount we want. It's a good idea to check with someone running a G-Body at your local track to see how much wedge (1/2 inch to 3/4 inch) he is running because unlike his, yours will be non-adjustable. Once you have jacked in your wedge, go just a smidge further to allow for rollcage deflection and set your jackstand height close, shimming if needed. Now you can weld your rollcage into place and the wedged chassis will stay in place as well. I've seen people put things up in spring buckets (like push mower tires and wheels) but tech people seem to find things like that, but a "bent frame," isn't much a boy or girl can do about that! Oh yeah, don't forget to tighten your body mount bolts.
