David,
Go out to their web site (
http://www.jblmotor.com/chassis.htm). Here you will find many detailed shots of their chassis. They also have drawings of their chassis as well.
I went down and visited Richard and Dave a few weeks ago at their shop. Very impressive car and extremely knowledgeable people! Barring aerodynamics, I truly believe a JBL will keep up with ANY super exotic on a track! The irony is that I'm trying to decide between a Kirkham and a JBL. Very different cars but both are highly desirable top end cobras!!! Decisions...decisions!
