"The quick ratio rack and pinion gear set is perhaps the most underrated performance part around. The Quaife rack and pinion gears simply replace the existing pieces inside your stock steering rack housing. More rapid steering response is felt with an average of 25 percent reduction in ratio, resulting in fewer turns lock-to-lock. This translates into much quicker steering and turn in at the cost of a slight increase in effort. A must for autocross, drifting, and track work. Designed to fit manual steering racks only. Not for power steering." (quote from King Motorsport)
All that means is that you cant use it on a car that does have power steering.
I am pretty sure that no USDM CRX came with it. Maybe teh canadian models did?
