Has anybody ever used spring spacers on their rear springs? Do they work? Thanks.

xhubby are you asking about spacers that go under the spring to change ride heights an crossweight or the spring rubbers that go between the coils to stiffen the spring. cd2

cd2, I'm talking about the type that go between the coils to change spring rate.

I've used them a ton, I used to do that >bad word PAVEMENT< racing, and when I came back to the dirt I brought them with me. People laughed until I won and my friend that borrowed them started winning.

I was using the "black" style, a full one added about 40# spring rate, and we were using them on three bar cars. The most common use was to add one to the LR when the track got slick to help FWD bite.

Thanks mod4. That's what I was wondering. We also have a 3-link, & was thinking about using one with the same scenerio. Do you need to take a ride height measurement, then add the spacer, then bring the ride height back to the original measurement?

Just to clarify MOd4.........

when you used the spring rubber in the LR it was good for about 40#'s....Have you ever used one in the RF....I was told it was about the equivalent of 25#'s in the front.


Does that make sense that a spring rubber would have more affect on a rear spring than a front spring.......

Bought a black one, but haven't used it yet.

Tyrin' to get some ideas ...........

TIA

What I did was use a Spring Rate Checker, none of my Springs were ever dead on (my 800 RF was 778, my LR was 13 pounds off)

I would then add the rubber and recheck the rate. But the important thing here isn't Spring Rate so much, we don't race Spring Checkers, lol.

Right or Wrong, this was MY thinking - by adding a rubber, I was not increasing the Static weight, I was only changing the Dynamic weight. Meaning until the LR Spring got loaded, it didn't know there was a rubber there. Thats the way I felt about it.

I never changed my ride heights, dirt or pavement. I had a VERY fast pavement car that from hot laps to feature, two half Spring rubbers and 2lbs of air could make me a 5th place car or almost lap the field .... think about it

xhubby They work great.Have added one or two in the L.F. on dry slick to tighten up on entry an have added to left rear to get off corner better. You can get them for regular springs or coil over springs. cd2

Thanks alot for the input guys. It seems that adding a spacer would be alot easier than messing with weight jacks, or changing springs.

you will have to readjust corner hieght, check it before you put it in, then put it back where it was.
