@Gary B. , I like Stan's summary of the handling dilemma we face with these cars.
We all like sports cars and the way they're supposed to handle (or we wouldn't be here), but we're stuck driving 90-year-old suspensions that don't handle anywhere close to a modern sports car or even a typical modern, econobox sedan.
Period.
Adding an (anti)sway bar or tweaking the shocks may make some small difference but still doesn't confront the elephant in the room. Our 'sports' cars simply are not sports cars by today's standards.
Which isn't to say you can't have a lot of fun by learning to get the most out of what their 1930's tech has to offer, but adjusting your expectations is probably more realistic than adjusting your front end.
Spend as much as you want, this ain't never gonna be an M3 or a Cayman.
If you can get past that, though, you may find other worlds opening. Most of the 'fun' roads near me are rural farm or connecting roads laid out in the 1890s, probably paved in the 1930s and maybe only slightly regraded since then. The surface is rough macadam, the grading follows the landscape, and even a modern car is sliding around pretty good by 70 mph. I take these roads 10-15 mph slower in the Speedster and usually end up having fun doing that.
Tell us a little more about what specifically bothers you with how the suspension performs. A 'sway' bar will flatten out the cornering a bit, but won't necessarily give you any more grip. Grip has mostly to do with suspension geometry and how well the tire is allowed to follow the road surface, and like Stan says, that is pretty much baked in the cake unless you give up the front beam altogether.
Our weapons are mainly tire pressure, shock compliance, and springing stiffness. My car does have a front (EMPI) sway bar, and with that feels remarkably flat through the corners, but you can also feel the tires breaking free and sliding across the road surface much more than in any modern car. After a while, you can use that sliding to your advantage a little to tighten your line through a corner up to a point, but it's best worked up to gradually as you acquire the knack.
Watch some vintage racing footage from the 1950s where a photographer has set up on a corner and records a series of cars coming through. Notice how almost all are in two- or four-wheel drifts to a much greater extent than seems apparent in modern racing. And watch the see-sawing of the steering wheels to keep that little dance going.
If you can't drive the one you love, love the one you drive.
