It's going to be "very twitchy" (as it's now 12:1 steering) and on a car that's always on pavement and probably spends the majority of it's life going straight at highway speeds it's going to get tiresome. Track car, autocross car, rally car - different story. As we're on dirt most of the time, some of that "twitchy on pavement" is reduced.Danteneon wrote: Do you know of any problems with using one of those on a street driven car?
Why this works for rally: Let's take an example of a "L2 into R2" (Hard left turn into hard right turn) The wheel is 3 turns away from transitioning to the right hander. If you're going to go through there as fast as possible you're going to be cranking on the wheel - and using a fast "shuffle steer" or "hand over hand" method to turn the wheel 360 degrees 3 times.
With a faster rack or quickener you not only have less turns to make, but you can turn in faster with less effort. You can transition the car from turn to turn faster. This can make a difference when you have 1000 different corners to negotiate (stage rally).
There are some other things to consider:
You're going to work the crap out of your power steering pump, so it will also need to be modified to handle that speed of turn at those RPM's. (Most soccer moms don't go lock to lock at 5,500 RPM sideways.)
Lose that power steering - and you're in for a SERIOUS ARM WORKOUT.
This is why I brought the steering wheel 2" closer. The less reach you have to make to the wheel (elbow at 90 degrees - upper arms at side) the easier it is to steer in general (and I accept the possibility that I may lose PS during a rally).
Fun stuff tho!
