Granted Don, it may not be much, but the panhard bar does mess up the handling.... When you're really cranking it into a curve and the back end goes over a bump it will push the car considerably...

I've also been amazed at the IFS guys who will spend hours getting the front end geometry just right--then just hook up a panhard bar on the back because it's the generally accepted method of doing it....

As for naming some cars with Watts linkage......well, mine... Perhaps I'm not a pro shop, or even a shop anymore far as that goes but nevertheless, right is right and as long as there are curves and corners with bumps in them, a panhard bar will never be the correct method of controlling lateral movement of the rear end housing.....

On the rare occasions that I actually keep something I build long enough to actually get it completed, I'm not going to let something like a panhard bar instead of Watts linkage screw up the handling that I spent so many hours and $$$$$ getting correct on the front of the car... Maybe I just drive mine a bit harder then most or I'm just to particular about how the suspension works.... If a builder is not going to comprimise anything on the front suspension, why ignore the rear suspension????
