Lets start with the steering..........The IVA has some requirements surrounding the safety of the steering column. There are a number of ways to tackle this. If you can have more than 10degrees of angle between the column and the shaft that connects to the steering rack then this really helps. The J15 set up is boarder line, so I opted to use the Puma UJ that also has a collapsible component. This required a small shaft to be machined up that went through the front bulk head and onto the steering rack. OK, straightforward.......well, not really. Although it sounds obvious, by adding another UJ in the system, you also introduce some sag in the column. This sag manifests itself to the shaft flying around all over the place with you turn the wheel....Most certainly not ideal!. The 'simple' fix was to introduce a bearing to hold the shaft in position. I won't bore you with the details, but this turned out to be a bigger job than first expected due to the proximity of the bolts associated with the steering shaft.
Anyway.....with bearing installed with a stand off, all now works nicely with no play and a smooth action.
As you may be aware, I’m going to use a small digital dash…this comes with a sensor that is magnetic. The basic theory is you find somewhere on the car that is connected and revolves directly to the wheels (but has a magnetic high point), point the sensor at it and program in the amount of pulses per 1 revolution of the wheel (you also program in the tyre circumference). I found a convenient place on the drive shaft with three high points…..Hopefully, that should be the last time I need to think about the sensor placement….we will see!.
