These cars are really like a girlfriend. If they make you happy then they will do just fine. As far as the rear suspension goes. If you truly are happy with the performance of your car as it is then I say damn the critics and enjoy you hard won accomplishment. Go ahead and drive it awhile and when YOU can see the benefit in modifications then do it on your own timetable.
All these cars can be improved upon. Just look at what some of the guys are doing to brand new CAV's and the like. The most important thing is to make the car safe and keep it that way as you begin to make modifications.
Be careful what materials you use and who welds up your suspension parts. Be sure to have someone who is familiar and experienced with the special requirements of fabrication and welding chrome for example. Also be aware that light as possible isn't really the best way to go when building a road car. There are a lot of thing that work very well on racetracks that will either waste a lot of money on unnecessary maintenance of be downright dangerous on a road car. Over reliance on rod ends is a example here. I bet I start a row with that one! Just make it good and strong. You will be a lot happier in the long term.
I personally enjoy the learning process and would recommend you review several good books on suspension fabrication and design. A good start would be the series of books, Tune to win, etc. by Carroll Smith or the race car engineering book by Paul Van Valkenburgh. There are many others. All have good stuff in them.
