it is probably time to replace the mono, most builders try to get racers to replace after 5 -6 races. This may be a bit drastic, but you get the idea. If you remove the leaf, you will most likely be able to see the spring de-arched. I have at times layed the leaf over a section of rail-road tie and beat it back into shape with a large hammer (an anvil would also work).

What spring are you running on the right rear and is it a 20# mono?

Good Move on the 35# mono but I agree with the provious post you will need to go to a 150# on the right rear assuming that the spring is located somewhere close to the leaf spring location. The more offset to the center of the car the coil is the STIFFER the spring will have to be. I further believe that you may need to run a 200# left rear in lieu of a 175 stack. You have to remember that the wrap-up of the rearend is substantially controlled by the left rear spring only. We have gone up to a 225# lr for this purpose. We experimented the other night ti tighten the car we put a stiffer spring in the right rear. Wrong way, for conventional thinking but, it tild us that our right rear set-up was way too soft and that the stiffer spring helped support the right rear better to get teh weight off of the right rear and back on the left where it belonged. We went softer first and boy was it loose, car would not get off of the right rear. The moral to the story is don't be scared to stiffent teh right rear a little with these cars it may pay off with a more consistant car.

Hope you dont mind me jumping in here . I have a mono leaf on both sides , Was thinking about putting a stack leaf on the left rear , All the cars that i have seen with the stack leaf has them mounted with a shackle ,, I have sliders and was wondering if i can use the sliders or do i need the shackles ??? Also i guess i would get rid of the 5th arm right ???? Thanks for any help .

Sliders will work just fine but make sure that you have proper travel. On the left rear there should be 1 1/2" to 2" travel remaining on the rear of the slider. the opposie is true for the right rear. The stack leaf on the left rear is acting as the traction control this is why the left rear is stiffer and needs to have some strangth on the front of the leaf. We clamp the front of the leaf at the eye to stiffen the main leaf for better wrap-up control. once you get everything set, our car has proven to be tretty consistant and is pretty good on all tracks. Medium to dry it likes the best. Heavy stuff, the coils have a little advantage but many dial themselves right out of the game.
