RideTech 33 Ford

Well, we have resolved the spark scatter problem. It was just a rotor phasing problem...no big deal, but took a few hours to identify.

The steering problem was a little tougher. The OEM FFR steering system was apparantly intended to turn a narrow tire. We are using a 295mm tire. When I turned the wheel you could watch the rack visibly flex. It would encounter a significant bind at around a half turn of input. The size of the rack components was compounded by the rear steer configuration, very short steering arms, and the incorrect placement of the rack itself. Totally unacceptable.
After more research and conversation we have decided to cut bait on that system and redo it completely as a front steer Woodward power rack. This will allow exact placement to optimize bumpsteer and Ackerman, as well as providing tuning capabilities for feel. The Woodward components are true racing components that are completely capable of withstanding the forces imposed on them by this car.

I had assumed that FFR had designed this steering system anticipating this kind of use and had not paid a lot of attention to it. After encountering problems I called my friend Chris Alston who was a seriously good source of valuable information. He then referred me to Tony Woodward who spent a couple hours filling me in on the finer points of rack and pinion steering systems. Tony is a classic example of "paying for a degree in steering and getting his parts for free". Knowledgeable, articulate, friendly, experienced, realistic, and able to relate to whatever level of driving you are attempting.

Now we get to spend a few DAYS sawing the frontend off the car and installing a proper steering system. I still hope to make it to Nashville next weekend.

Don't get me wrong...I'm not blaming FFR completely for any of this. Their system would likely work fine with their recommended tire sizes in a "civilian" environment. Obviously we are working with neither. My aggravation is only with myself. I should have not assumed that this part of the car would be any less customized than the rest of it. I should had examined, evaluated, and fixed it months ago.
We will fix it now. It will be cool and fast. Its what we does.
