I'll Chime in with my .02, I went through this whole exercise a year or so ago, reading everything I could read and asking everyone I could ask. There is no Ideal, just a mixed bag of trade off's. 1st trade off is that you got to get the motor in between there somewhere, second the wheels and tires can't stick outside the fenders (in our version of the sport anyway)
I started with the wheel's and tires I wanted to run, 17x9.5 Z06 wheels. Second was the overal width of the track so I won't rub the fenders. I knew I wanted to run stock Corvette (C5) parts, so the spindles and control arm dimensions were fixed. But to get this config under the front of my camaro it ended up being about 5" narrower than the stock vette geometry. So I had to go back to the drawing board and refigure all the geometry with the new track. I ended up with the roll center about 1.5" above ground. From there I tried to optimize camber gain and minimize bump steer. The Rack location is the hardest part, With some help from Matt at AME we came up with a solution to lower the mounting points on the control arms and get the rack low enough to clear the engine. I also set my engine back about 1.5 inches so that the rack sits in the "sweet" spot behind the balencer and in front of the pan. Every 1/4" helps.
Everything on my suspension is adjustable, lower control arms, upper control arms, tie rod mounts ect... I havn't driven the car yet so I can't give you any real world feedback, But I will say that My Daily Driver Trans AM that I auto x with is a handful on the street in full auto X trim. There are to many inperfections in the road, it wants to dart off in any number of directions and rides like a brick. After every event I dial back down the shocks to a softer setting to make it bearable.
My Two cents, hope it helps.
