COT bad handling / coil bind



Avatar7_150

When I drove race cars and I had a handling problem, one of the things I looked for was a coil bind. When you have a coil bind, the spring rate goes to infinity.

Now, modern NASCAR cars run a "coil bind" setup to get the car down on the ground to get the aero downforce. They run soft springs that sag to the rubber bump stops. Could the fact that the springs are now rubber bumpers have anything to do with the inconsistency of the car's handling? Please ask Rick.
Thanks.

Good question. You should also send Cutler a message because I know he was soliciting questions for Rick.

I hope you have heard some of our discussions about this with Rick. From what I understand, the bump stops basically have a similar effect to the coil bind if you're riding on them--you're getting all your spring rate from the tire and whatever the chassis has (and the rubber too, as you suggest, I guess). At that point you're in a pretty small window to hit that "sweet spot," and with a new car you're still learning it probably gets that much harder.

Brian Vickers was talking about how they changed theirs by a sixteenth of an inch and it made an average car a great car.

In my little ole opinion and Nascar can't tell me to shut up, the CON(Car of Now) is crap. Yes, it has great safety features, but it doesn't show me anything else that makes me cry out OH LORDY!
