Is anyone using fiberglass leaf springs in a 65 mustang? I'm thinking about a set for my drag car, Has a ladder/leaf set-up with stock springs. I figured it would be a quick way to save some weight, but I'm not sure on spring rates or how they would effect suspension movement.

Mark, we do indeed have fiberglass leaf springs on our car. It took off over 50 lbs when we took off the shelby springs we had on the car. The spring rate will depend on the weight of your car. If you plan to set it up as a SuperStock car, knowing the weight will be 2945 minimum in SS/LA the rate will need to be 175lbs.To correct Don, we have an adjustable ladder bar set up on it using a full floater, also with a single adjustable shock on the rear. At least for this moment  we are working with someone for a stock mount double adjustable rear and super trick double adjustable front. When you do this, you will need a custom built floater to fit the width of the springs. Mark, with your car, has there been any suspension work, or upgrades done? If not, you should look at Mark Tallent's website for the front end parts. Those will be just as critical in making the car work, and work well. ------------------

Tony, Thanks for your input!. My car already has a housing floater, nothing trick, just a couple of 1/2" bolts that the spring can slide on. The car also has 13x31" slicks that I think are too big for the motor, however it does hook, so much so that I designed and built a front suspension travel limiter. The car weighs 2960# with my butt in the seat.The company I contacted was flex i form , they suggested a 225# spring.The ladder bars only have one mounting point so I can't adjust them.Are four links legal in S/S? Thanks again, Mark

For $400 you get not only a great reacting spring, but you are losing maybe 50-70 pounds of weight as well...that's gonna help with handling AND acceleration.

While steel monoleafs are heavier than fiberglass they are more than half the weight of stock springs. I had fiberglass monos on my car and I replaced them with the Split-Monoleaf springs they had a higher spring rate and were more resistant to separation. This is very good for a car that hits hard and I felt that giving up the weight savings was offset by a higher rate.------------------

Mark, What do you mean by, separation? Do you mean that the fiberglass leaf was splitting along its length or ? Ryan

He is referring to body to tire separation Ryan and that is subject to debate.
While Mark's car may have experienced some problems, I feel it was more due to wrong rate and shock issues.
