Hank,

I am happy to answer questions! That is why I am posting the entire book in jpg form on this site. No one can comment on the pdf files on our website. You have very good questions.

Because the chassis was machined entirely from a billet there was no need to adjust the front control arms. The entire kinematics of the suspension was worked out in Solidworks and then set. The front suspension was never meant to be adjustable. The only adjustable alignment in the front suspension is by the steering tie rods to set toe. In other words, we designed the suspension exactly how we wanted it, machined it exactly how we wanted it, and then left it.

We made a fixture for the front suspension control arms to set the length of the rod ends and then tightened them up.

It is a tremendous testament to Thomas' vision and engineering skills the car handled superbly out of the box. He has spent his life reading suspension books. The car was a very unique combination of street suspension and racing suspension.

We didn't fuel injection for 2 reasons. 1, it never works right. We have messed with it for years and have never seen one that drives as well as a carburetor. The mapping is simply too complicated. Ford, GM, and company spend 6 months to map the fuel injection on their new cars. It is tremendously difficult to set up properly.

2. There was no room. We moved the engine back 6 inches and so there was no way stacks would have fit under the windshield cowl.
