I have read gkull a few time mention: "One problem about our c-3's is that the steering is tooooooo fast"

For years my 69 has had the tie-rods in the fast steering. I can't imagine it would much affect on the street. But for the road course I am thinking gkull had it right. Maybe I am just getting old.

Anyone switch back and forth? Is the difference noticeable? I have to get the car aligned, so this may be a good time to make the swap and check it out.

Anything from guys that have made the switch, chime it.

As speed goes up you want more turns on the steering wheel to move the tires lock to lock.

Fast steering is for auto-X

The tie rod mounting point helps. Also use a high ratio steering box. Then when you are in a 4 wheel drift in a turn you can saw the steering wheel back and forth to make minor corrections. Out on road coarses with long straights it give you a time to relax and think about how you are going to do that turn that you blew the last lap better. It makes our Vettes more stable and controllable at really high speeds. Like these open highway sanctioned road races where you are driving over 150 mph for 90 some miles

Agree with gkull, "quick" steering favors point & shoot corners, while "slow" steering favors fast sweepers.

FWIW to your deliberations, the delta between the two ratio settings is ~15%, "quick"/PS being 17.6:1 and "slow"/manual being 20.2:1. (Note that these are both slower than either setting with the Borgeson box.) I've driven standard box, manual C3s in both settings and found the difference is definitely noticeable, particularly in parking mode. My $.02, HTH.

Corvette racer with one hell of a lot of experience, been on here forever and a day......

He was also the first to reply.

I am redoing the rear with 1/4 toe-in. One modification at a time.
But I may switch the steering and see how that goes for a track like Lime Rock.

TheSkunkWorks

Ah, The Downhill. Daunting corner, that. Yes, I'd definitely test whether the slower setting yielded a bit more driver confidence there, and preferable by trial without error.

Best downhill was Bridgehampton. Down the main straight at 150...
HEY...WHERE THE TRACK GO?
Under the bridge....Oh...there it is. But even then, the tiniest turn of the wheel got you through there no issue.

So, if I am reading you guys right, the slow steering isn't the way to go. I had had it there for so long, I forgot how the other setting will handle.

TheSkunkWorks

No, I am suggesting that you should try the slower setting for such turns as LRP Downhill. Anything that gives you more confidence there should improve your lap consistency, if not better you overall best ET. At least, that's how things always worked for me when racing there in winged formula cars. YMMV

I for one prefer the quick steering. My C4 race car has a tight ratio steering rack (about 2 turns lock to lock) and and a small diameter wheel. You just have to compensate your input speed on the wheel. I will probably keep my C3 in the fast holes even when I upgrade to a Borgeson or some faster box. Thats just my personal preference though.

gkull

I just like high ratio because I run over the rumble strips depending on the corner either at the Apex before the Apex after the Apex
