Mocking up the new rear frame rails in wood first because it is way easier to cut quickly and throw in the garbage.... Getting pretty close on the angles / lengths. Will likely end up building this out of 2x3x11g tube. Here it is 1.75x1.75 pieces of wood.
On other progress, the garage was taken over by a barrage of house projects. Garage door opener needed to be replaced already, a big cedar playscape needed to be refinished and installed in the back yard, a 10x14 rug is in a box and in the garage needs to be moved inside, and on and on and on. The garage had turned completely into a non-usable space. I've since fixed that by getting the playscape done, and getting some of those Monkey Bars shelves. They hold 1000lbs each and are a 2' x 4' shelf about 7ft above the floor and have hooks to also hang stuff up. Made a big difference.
The compressor is wired and running and a 3/4" Rapid Air kit brings the air to 3 outlets, 2 on the back wall of the garage (right on the below picture) and 1 between the 2 garage doors (left on below picture). Glad that's done.
The car is up on the chassis table, albeit not at ride height or in position. It's currently at a 3" ride height with no rake. Cool but not practical. Planning to move it up 2-2.5 inches and give it a bit of rake (0.5" - 1"). With that done, I built the support for the BMW subframe based off measurements I took on an actual car. That allowed me to move on to the mock up phase. Now ready to start making the steel pieces. Unfortunately, I think this is the easy part. Getting the car and subframe positioned precisely is my biggest concern. Even with the amount of adjustment built into these production suspensions, I want to get it as close as possible. Once I'm at that point, I need to check if my idea about tying into the existing body will work. The way I'm planning to do that would make it relatively easy and not very expensive.
