I have Limiter Chains on both my Right Rear and Left Rear of my Lazer Chassis by Bernheisel. I have both chains mounted solid on chassis and rear end and im thinking of putting rubber bushings on them does any one notice much of a difference between having them mounted with rubber or soild? I have always run them solid...
I have my chain on a rubber bump stop. Less shock in the suspension is always going to be better if you ask me.

Only time I wouldn't run one is if you were a clamp car. The rubber has some give to it and it wouldn't be hard to over index a clamp car. Jmo

I also find this strange. Geometry that would encourage over-index would be more beneficial on a lr behind deal than a clamp car, IMO. Birdcage index has no impact on wheel rate with a clamp car. All that matters is steer and thrust angle.Quote:

Clamp cars aren't anymore sensitive to over indexing than a spring behind car. If the suspension is close to over indexing, adding a biscuit could push it over the edge no matter what. Spring location has relatively zero effect on birdcage indexing. Think about it.
clamp cars are hard on chains and shocks due to the clamp rolling into spring, which is a bit more violent than a spring behind, if you have to get on and of throttle.
in my experience clamp cars do not need the upper and lower LR bar angles a spring behind car does, due to the rotation forces of rear end on spring, and the lift applied to chassis.
But with a spring behind car, you typically have to keep car on bars to keep traction.
Clamp cars general speaking do not have to stay on bars, and when let down on corner entry, when throttle is applied, it typically reacts very fast and tops out quickly. a rubber biscuit would aid in the initial hit of a chain.
Just have to watch how much biscuit compresses, to know how much to compensate with in the length of chain.
Just my 2 cents
