Absolutely, and I'd say 6 to 7 degrees positive front caster. 1/16" total toe in front and back is a good handling point. Not more than 1.5 degrees front negative camber, and for a swing axle car, I'd not go more than 3 degrees negative camber. IRS rear, probably somewhat less at about 1.5 to 2 degrees rear negative camber. Sway bars/camber compensator will also play a big role on how your speedy (or coupe) handle. Now, I don't own a speedster, and holding out for a Beck coupe for now. Water cooled of course. Tons of seat time in 356's and early 912/911 race cars though. Built a fair share of Super Vee's in the distant past too.
