Srhutch, Yes I’ve got to agree, not much surface area on the head of the bolt.
Chris D, in the post when I asked about jacking the car up earlier, someone posted a photo of a forward jacking pad in the middle, up front but that was on an M version, the non-M does not have the pad. If there is a center front jacking point on non-M, it’s under the plastic splash panel...or the metal panel, so you’ve got to jack the car up to get that off...There in lies the problem.
In that previous post some people mentioned making a lifting bar that spanned front and rear jacking pads and you could lift one side of the car at one time. I started making one out of some pretty heavy rectangular steel tube. It was bending in the middle (didn’t take a permanent set) but it was touching the bottom of the body. I had some angle iron laying around and I welded it in the middle of the part. The whole bar is 4 feet long and the angle iron is about 2 feet. It did better but still bent enough to touch the body before the rear tire was off the ground. I plan on getting more angle and covering the whole length. I will post the details of the bar if it works.
