Has anyone tried this, using two, what look like extremly light springs on RR one ontop, one behind shock infront. I've seen some latemodels try this, but never on a Mod before a Peirce mod showed up with it. What would it do for handling?

Thanks Emod1

Been wondering the same thing as a Pierce at our track has the same thing. Only thing is rule says 1 spring and shock per wheel for mods.

it helps intial side bite with spring in front and side bite with on top.
it only works on dry slick tracks, what I was told never ran it though

Is the spring in front or back and do you clamp to the rear end or float it on the bird cage, Never heard of a mod doing that only those eastern mods that you sit in the middle of them, They run that set-up a lot

Bob talked about it this year at the seminar, Brett Rehnbergen (sp?) ran it out in New York.

i see Brett running that setup on his late model when they ran the WOO race at Fulton last month. Timed trialed second and finished top five in feature against the dirty dozen. His car looked really stuck well on the bottom of the track on the slick. then again thats a late model and we play in mods. little difference in treads between us.

We are seeing a few guys running an 80lb (helper)coilover spring with the torsion bar set ups on the RR in the Northeast mods...It is supposed to increase spring rate later into the corner and assist forward bite. It works similar to a progressive rate spring...As the chassis roll increases it compresses the spring
