Have a new 2018 Grand Sport (first vette for me) and have noticed that when making low speed tight turns, such as backing out of driveway onto street or pulling into parking spots that it feels as if front tires are binding. Anyone else notice anything like this?
Hey Sockguy... this is normal. we all get it... This is an explanation I posted a long time ago and will repost it here. Hope it answers your question...
Re-post
regarding your "hop hop" as it is a common occurrence (especially with the C6 and C7) and we have lots of new members coming on board that may be interested...
Temperature will only make very marginal differences in the wheel hop you refer to as what you are experiencing is explained in the Ackerman Steering geometry Principle.The quick and dirty explanation (at least I hope it will be) is:
The Corvette Stingray does not have perfect Ackerman (This is not a flaw. This is a happy medium for a combination track and street car. Perfect Ackerman would not handle as well on the track and about the only alternative to have perfect Ackerman and a vehicle that handles well on the track would be to have another differential installed between the front wheels.
In my feeble attempt at explanation, the front of the car and thus the front tires from one side of the car to the other both turn around the same radius point. During a turn each have a different length turning radius and angle; a shorter radius and tighter curve for the inside tire and a longer radius and flatter curve for the outside tire. This means the tire on the outside of the turn is travelling a longer arc distance than the inside tire. This results in the tires fighting with each other in their attempt to equalize themselves, and in a very sharp turn angle, this results in hop hop... crow hop...tire scrub..tire slip. there are lots of names for it. The wider stance, the lower profile tires, the sharpness of the steering angle, the camber and caster of the wheels, the width of the tires, the stickiness of the tires and the temperature all have some effect on the magnitude of slip which equates to how much you can actually feel the slip, but the tire fight is always there when the wheels are turned . It happens both in reverse and forward but we seem to turn the steering sharper much more often in reverse than when we are going forward. Except in parking lots... lol
