A buddy of mine has a '94 Flexi Flyer leaf spring car. At the track he runs at we have noticed that nobody runs this set up. Is it a waste of time to run it against guys with 3-links and mono-leaf cars? Also can the rear suspension be swapped out to a 3-link?
Thanks!

I agree with worldcom, If your going to buy a chassis, get a up to date one. and if your going for a leaf chassis, then get you a FR-1. I drove one for 3 yrs and they are fast and competitive.
This year i wanted to try something different, i am running a swing arm Z-link car, It is fast also and seems to fit my driving style better, but you sure have to work on them more to be competitive.
A Leaf car would be a good starting point if your new to the modified class.

Had a leaf car could run good on tacky track.Once track went slick would fall back.My car was only a stack leaf car.tried all we knew to make work and coundnt stay competive.We converted it over to a three link.I am very happy with the three link have won several heats and running in top five now in features.

What purpose does the mono leaf serve other than rear end location do any of the chassis use a jbar or a pan hard bar with the mono leafs Im still in the stage of what to start out with so Im gonna be asking a lot of questions.....Towman

Towman, stay away from jbars and panhard bars with leafs... All you will get is an ill-handling ball of rear suspension bind. The leals act as their own panhard assembly and cusioned, at that. The Leafs are VERY simple to set roll center, not so easy to make adjustments at the track, but still fairly simple. The rear roll center of a link car is the height of a straight line half the distance between the panhard bar mounts. The leafs are at half the distance between the bottom of the axle tube and the top of the leaf. The reason Late models seldom are on leafs is for adjustability. You really don't need that adjustability with leafs. Once you get fast, you are going to be fast wherever you go.

To answer you question about the mono... These are used to get the panhard and torque control abilities of the leaf and the ease of adjustment of the coil... It doesn't take very long to change a coil spring, but it's 6 bolts to do a leaf.

Thanks for the info guys. From what you guys have said I think that the leafs will be good enough for now.

But I am not sure that my other question got answered. Is it feasible to swap out the leafs and put in a 3 link?

Thanks

My 94 Flexi had the mounts to run either leafs or three link with eliminators. So it would have been an easy change. (mine was set-up as a three link car)
Call Flexi and they can let you know about the cost of making the changes (radius rods, Springs, third link, shocks etc).

Knightrider, you asked if it was feasable?

Well, I don't know about feasable, but I know 2 guys (father & son) that recently converted their Late Models from leaf to 3-link.

Results: They've gotten even faster than they were before.

Takes a little time & $s, but it can be done.
