got a pic somewhere comparing to std rack and Quaife Quick Rack...
Top: Quaife Rack - Straight cut teeth 25T, different angle and larger pinion 10T. Quaife is 2.5 lock-lock.
Bottom: Manual Rack - also 25T, but Pinion 7T = 3.6 turns lock-lock.
Left: Quaife Pinion
Right: Manual Pinion
Note: Quaife Rack does NOT give more lock! but is has more direct and quicker steering response, although heavier.
Some people have had extra teeth cut into the Quaife rack to increase lock.
Also GTV use power-steering arms also.
