I just finished jacking up my C5 for the first time. I made a 24" long lift beam that would fit my floor jack from a piece of 2" x 6" x 3/16" wall steel tubing and welded a post in the center that fits in the pad on the jack. I glued and riveted a 1/4" thick piece of rubber cut from a truck mud flap on top for a non-skid surface. In order to get the car high enough for the jack to go under the suspension cross-members, I made 4 wooden "ramps" from a 2 x 12 that were 24" long and cut the ends to a 30 degree bevel.
I know using the wood ramps is a common practice, but what is the trick to keep the ramps on the rear from slipping (I didn't have any trouble with the fronts)? I tried easing up and rolling up on them several times, but ended up spinning the tires on the smooth concrete floor. One rolling attempt ended up shooting both ramps under and out the rear of the tires. I finally had my wife sit in the car and rolled the rear only up on the ramps by pushing the car.
Don't ask me why, but turn the boards around & go up with square end against the tire, tire grabs the edge & just goes right on up, stagger the boards, so that it goes up on one & then the next. I tried the slant cut too, & did same thing you did, shot them across garage. I used 2X12 also.
