Chris,
Excellent fabrication. We should compare notes. I'm working on a 914 SCCA production racer, too, for a while now. The big difference is you've been racing yours for a while I've been running an ITB car.... and I'm jealous. My 914 has only been to auto-x's. Here are some of my notes: I'm been redoing the front suspension on my 914 with the goal of improving geometry. I'm going to toss the control arms and use 2 tubes on either side with rod ends on both ends of each tube. I wrote a little spreadsheet program that calculates roll centers under different conditions and concluded that I need to extend these tubes to the center of the car and make them level at ride height. The only thing I was doing to the rear was to fabricate some sperical bearing mounts on the chassis and plug the trailing arm with threaded plugs....... and make sure I've got enough travel to align toe and camber. Now, to my point.... Given that in production we have to stay with the "same type" of suspension that came on the car. In the rear, we're stuck with a trailing arm setup. Everything I read says there's not much one can do to improve it, unless you lengthen it significantly to reduce the wheelbase change with travel. Is that what geometry you're trying to improve? or have I missed something? Thanks, Kevin |
