Steering ratios

Does z06 have a faster steering ratio than regular c5?

Faster than late model c4 (like the 1996 LT4 coupe

TIA.

P/s pump different/ p/s cooler?

No.

All Corvettes since 1990 have the same 16 to 1 ratio. The reason the C4 feels faster is that the wheelbase is nearly a foot shorter.

The 1989 coupe Z51 was the last quick steer (13.3 to 1) made.

I have a related question: the steering ratio is the same 16.1:1 for the coupe and convertible as for the Z06, yet the turns lock to lock for the first two is 2.66 and for the Z06 is 2.46 - any idea why/how that is with the same ratio?

I assume it's because of the larger wheels/tires on the Z06, and is also related to the difference in turning diameter (larger for the Z06). True?

As I understand it, the rack & pinion in the C5 has variable-effort boost that provides continuous speed-sensitive changes to the steering effort needed. I don't know exactly how they do that, but the system calculates vehicle speed and lateral acceleration and uses a combination of hydraulics, electronics and magnetics to vary the steering boost according to what the car's doing. It seems to provide a much more sensitive feel than my C4 ever has, especially when autocrossing.

First time out on course in the C5 I hit three of the five cones in an opening slalom by turning in where I always had in the C4 - the Z06 responded so much more crisply I had to change how I drove to get through it. The LS6 isn't the only reason the Z06 is much quicker than my LT4 coupe
