Ok. More complicated than i first thought.
Thanks Mike, thanks Jac. I have written to Kiley Clinton and waiting their reply.
Meantime even 2.25 lock to lock would be ok (provided improved turning circle).
I will Keep you advised if I learn anything new.
Thanks guys.
Just to add to the complications, as Jac points out, you cannot compare steering turns lock to lock between different cars/manufacturers which have different pick up points, geometries, wheels and tyres. For instance, I do know that my Southern GT has a tighter turning circle than a GTD.
Like you, I too decided that I wanted quicker steering but could not find an aftermarket rack of the correct length (ie to not affect the complete lack of bump steer on the SGT), so I went the route of having a new rack and pinion made to fit the same steering rack. It is now a perfect rate for track work, corrections are now just the merest flick of the wrists, but using your specs you would disagree as it is 2.5 turns lock to lock, but, as I said, it has a large lock, small turning circle.
Interestingly, despite being quick, I do not find it overly heavy manoeuvring and parking (my other half drives it too without problem), which leads me to say that in my experience, with my car, I do not understand the need to fit power steering. I guess it just proves the point that they are all different.
Incidentally, I wouldn't expect that changing the rack will improve your turning circle, normally it is the wheel/ tyre fouling which limits it. What rack does the MDA use as standard?
