Leaf spring problem

[coln72]

Could you use pump up shocks (air jackers - like they use to raise up the back of the car if you are towing) but hook them up independantly. This should enable you to load up the RR a bit.

Before you say they dont make them for corolla's, try HK/T/G Monaro (these are what I ran on another rolla) or some Commodore wagons as thay are the same dimensions.

Quick scan of the Rule Bible reveals words like No specialist Shocks like and inc. Pump Ups. Shocks have to be std road going but shocks Carrerra Bilstein etc are outlawed so going have to go inside the shocks and play. Not allowed to run a rear sway bar either. So Dennis wouldn't that reverse spring idea sort of work like a sway bar. And if it's done only on the left side (oval racing) it would act like a oneway sway bar??????????? It would change the leaf rate to a increasing rate with roll - yes? Which is sort of the reverse to a std leaf? Effectively I see it tieing the left rear corner of the car down. Which should be a good thing as there are plenty of diagonal roll overs in this class. Anyway I'd like to try it out in about three weeks. Unless u guys think I'm off the planet. Speak to me.........trikes

Hi Trikes, I think the rate will change. In particular I would expect it to stiffen as soon as the reversed leaf began to adopt it's original curvature. However, if this happened at all suddenly, that would be a BAD THING.

I reckon a bigger effect would simply be lowering that corner of the car so, in effect, the car was balanced on the rear wheel on the opposite side & the front one on the same side. I don't know anything about ovals, but is does sound a bit like the 'jacking' built into some of these? Again, it might be a bit too dramatic. On the car I saw it lowered the back about 2". I'd certainly do corner weights before driving it - could be dangerous doing on one side only. Best of luck.
