I think you'll probably find that to get your car the way you want it will be swiss cheese when your done. Check out

for some ideas. You'll be hacking up the body a bunch which is just fine and like you said, it will be frustrating. Suspension geometry is not a straightforward leap. Car companies have been trying to copy BMW's strut suspension for a long time because it is so good, and you'd think it would be easy, but it's not. All I'm saying is that although it looks good on paper, actually getting it done is a WHOLE other problem.
BTW, my setup is not yet for sale, and it would have to be worth selling before I would. But the difference between it and other options is that it only requires 2 small pieces be removed from the body and 2 from the pan, the one from Eyeball Engineering only requires the 2 pieces from the body, but it is not for sale either. The goal with these 2 design is that body preservation was a formost thought.
Good luck!
