This is the general advise I got when asking the same thing.
Standard is too light, too many turns.
2.4 too twitchy on the road but perfect on track.
2.9 best balance for road and track.

I've just gone for a 2.8 for my sierra rack.
I could almost get away woth a standard rack but there's just a tiny amount too much lock for some of the tighter turns on trackdays - 2.8
should solve that but still allow enough precision to place the car properly on track without suffering any twitchiness.
Having said that, my mate uses the quikest rack Caterham do on his se7en and it's pretty perfect (1.8 turn IIRC).

Hi
with the Escort racks you will find that a STD travel and ratio is virtually useless.
The other options are a very rare Quaife 1.9 or a more common 2.2. Other rack manufacturers do 2.4 ratio as a quick rack. These are generally a 30%
ratio increase. There are some 2.9 lock to lock racks around but these are STD ratio with lock stops fitted so no benefit over a STD rack just less
travel.
The worst rack of the lot is the genuine Westfield item thats made by QH. That has reduced lock by not having the rack bar machined as far to give
less travel rather than lock stops fitted. It is sold as a quick rack but is actualy only an 18% increase in ratio.
In general a 2.4 is a good option for road and track use. A 2.2 or 1.9 are better suited to just track use.
Cheers Matt

My 2.9 is deffinatly a lower ratio than standard and had no lock stops fitted. I know because I had a standard (3.5?) rack to compare it with that I
had decided not to use.

Hi
They do not necessarily have lock stops added as an extra fitment on the ends. They don't machine the rack bar the same distance / length as per
the Westfield STD item.

...but when I compared my 2.9 with the standard one, it travelled the same distance but with less than3 turns compared to over 3.5 turns.
I don't doubt that there are some like you say, or even them all possibly being like that now, but the one I have isn't.
