It looked so simple at first!

Thanks. I'm not quite sure which way I want to go on that myself yet. I'm trying to get all of the supporting hardware in place first. I will be shooting for the 350 HP level and staying rotary, so it will probably be a single turbo 13B REW based engine, we'll have to see when I get to that point.

While I was off playing farmer, I'm temporarily home as you can't cut corn in a snow storm, I ordered the upper A arms and hardware from pitstopusa.com. The parts are already here and exactly what I ordered. Which for those of you that know of my supplier travails, came as a pleasant surprise.

They are Joe's Racing upper arms made for racing, but should work for what I want. They provide for adjusting camber and caster with minimal fuss using spacers (the blue things in the back) and slugs to adjust side to side and up and down for roll center adjustments. The arms are replaceable in different lengths if I need to change the camber gain as the tire moves through it's arc. They use a standard screw in ball joint, which I will pick up locally.

The only concern that I have is that the arms are suspended with non compliant bearings instead of rubber or poly bushings. Which is great for free movement, but they may be a bit harsh on the street. They are not the load bearing arms, so it shouldn't be too bad. The only way to find out is to try it I guess. Appropriate since this whole thing is one big bloody experiment anyway.
