Will, the Centerline front springs are very good for the street and mild racing, and the rear springs for the 72-74 GTV in their catalog will give you a controlable oversteer without getting into dangerous territory. Just use stock shocks in the rear, or Koni red set on soft, (they are the same rate); and Koni yellow in the front set at soft to start with, follow the Koni web site on how to adjust them for your set-up and driving style. No rear antiroll bar.

Lower the car as much as you can for the terrain in your area so the oil pan doesn't drag. The lower the car, the less leverage in roll. Do it by eliminating the rubbers on the top or bottom of the front spring as needed to get the ride height you want. Make the rear the same as the front in ride height, even if you need to cut a bit off the open end of the rear spring. It will be a one to one ratio in the rear; cutting off one inch in static spring height will lower the rear one inch. It is about a 3 to 1 ratio in the front. Remove the rubber bump stops front and rear, they won't be needed with the stiffer springs, and can cause the car to spin if the car bottoms out on them.

Use stock bushings in the rear. The result you want is for the front to controll roll, and have the rear follow the front. Don't worry about roll centers, what we are trying to do is have matching roll couple: IE the rear rolls the same as the front in the middle of the corner, called neutral cornering

Use the Poly bushings for the caster rod in their (Centerline's) adjustable camber rods, and set the camber at one degree negitive (for the srteet), with caster set at minus 2 degrees; use slight toe out with radial tires, and slight toe in with bias ply tires.

Be sure that there is a Alfa Romeo lettering on the rear of your car, so the Porsche driver knows what blew past him. And have fun.

I've been using the above set up in cars I've built for years, with happy customers; and it is inexpensive to do. Hope this helps.
