Paul,
It takes me a while, but I eventually find out when people mention my name
What I liked about the Mumford Bars was the ability to adjust the roll centre. Here's a photo of a sports racer (Mallock) with the Mumford. you can see the two outer 6061T6 bars coming together in a "V" shape. The point at which they would intersect is the roll centre.
I haven't yet adjusted my car to feel the difference, but it's something that i will be playing with over the next couple of months.
Here's the new Superformance Super 7 replica, also with the Mumford.....
