Dual Rate Springs
I’ve been thinking about dual rate springs for a Peugeot 205 Gti hillclimb/sprint car that is also used on the road. My idea was to have a main spring of around 200 lbs/in and a tender spring of 1000 lbs/in
This would give an initial rate of 167 lbs/in, so fairly compliant, then after maybe an inch of travel the tender would go coil bound and the rate would stiffen up to 200 lbs/in.
This would hopefully keep the car compliant for rough airfield surfaces and on the road, but would help reducing roll when cornering without the downsides associated with stiffer ARB’s.
Question is what would the transition between the spring rates be like and how bigger percentage jump could you tolerate between the initial and main spring rates?
Cheers
Ed
