Raised Trailing Arm Pickup Points, Pictures of my progress Options

I finished welding the driver's side today.

Kevin,
Theoretically what you suggest is correct regarding longer arms both front and rear. In practice it is largely unnecessary. By limiting suspension travel with heavier springs and anti-sway bars the camber change is held within the desirable limits anyway.
One of my primary goals with my project is to keep the budget under control and develop alterations I can do for customers at a reasonable cost, and still get greatly improved performance.
I haven't done any suspension simulations, only real world testing. I get excellent tire wear and high levels of grip already with the changes I've made and the camber settings I use. The most recent changes should help further in this regard.
I think that raising the rear pickup points helps the tire go over a bump more smoothly because the tire isn't trying to move forward as it goes up, as it would with the stock pickups on a seriously lowered car. I guess that's another way of saying I'm trying to reduce the wheelbase change. (IMG:style_emoticons/default/smile.gif)
Your plan to make long tubular front arms means you will have to use coilovers. I have no desire to go that route. I also am not interested in altering the stock method of pivoting the rear arms, other than beefing up the attachments and using better bushing material. (BTW, I offer delrin bushing installation service with grease fittings for rear trailing arms that equals the needle bearing setup performancewise IMO, and at a lower price. $250 installed.)
I heartily subscribe to the KISS method of performance enhancement. (IMG:style_emoticons/default/wink.gif) Track time is more important to me for lowering my lap times than having the most trick setup. Fancy sh!t you are constantly playing with gets in the way of track time, therefore is undesirable IMO. Everything I have done so far is working pretty well, based on my results.
