OK, for some reason I don't feel confident in my setup knowledge today........so here's a question. I lost my RR shock mount during this weeks main. I basically have a solid 3 link rear and the shock is a 4010 bilstien. What handling effect would losing this shock have had? Entry? Exit?

Like I said, I'm pretty sure I know what effect it had, but I'm having trouble validating that in my head. That's where this board is so cool.

I would say it would affect the car all around the track because there would be nothing to control the violent movments of the spring. The wheel would just bounce up and down on the track.

Prob most noticeable on entry and middle of the corner though. As the car would prob just flop over there and then as the wheel encountered ruts or bumps it would just move up and down without any control.

It could also cause a loose out as the undampened tire/wheel could be bouncing instead of holding the tire to the track.
Remember a shock is more or less a timing device for the suspension. It lets the weight transfer sooner or late depending on valving but it also determines when it transfers back.

This is my first year running modifieds and the car that I bought also has a solid 3 link set-up. I have been told by the previous owner that I should change the car over to a 4 link set-up. I like the simplicity of the 3 link and find that some of the guys with the 4 link adjust themselves way out of wack. I guess my question would be, can I be competitive with what I have? We run on a slightly banked 1/3 mile. Thanx in advance.

blackbart,

What I would say is that if this is your first year stay with the 2 link. Unless you have lots of previous experince around modifieds there are plenty of adjustments you can do with teh 3 link while you get seat time. To me personally when set up right the 4 link is the best setup,BUT if you dont understand what you are doing then your right it is a lot easier to dial yourself out. Plus with a 3 link you can be a little off on the setup and still have a drivable car, with 4 link you need to keep it closer otherwise you just cant drive the thing.

I would believe anything could happen when you loose the shock. I watched Freiddie Smith run away from the feild at the late Model natonals at Eastbay here in FLorida this year with no right front shock or spring. He passed Bloomquist and the next corner ths right front fell and the spring came out, from that point on he checked out for about 65-70 laps when Oneal passed him. The car was FLYING but it was shacking itself apart and the vibrations were making his arms go numb. After he said it was because he was so tired and his arms were numb so he just couldn't hold it any more. It was shacking so bad the fuel cell and body were loose after the race.

Thanx a lot Dirtbuster, I appreciate the info. I was kinda already thinking along those lines, but, sometimes it feels better hearing it from someone else too.
