There is a link in the toolbox that may get you in the ballpark. Just have to measure coil diameter, wire diameter, and # of active coils. Then plug your #'s in and it'll show ya the spring rate. An easy way to do it, would be like everyone has said and take it to your local speed shop and have them rate it on a spring rater.

No speed shops for 250 miles.I'll try the jumping method and tighten my carburetor belt.

the best way to figure it is take them out buy new ones that are what you want then make up a weight on the old ones and sell them at a swap meet lol

now thats a good idea.actually ran 20 laps for test and tune sunday.the new motor pulled great and the car handled well compared to last year.the xtra horsepower changed everything and could feel changes with air pressure adjustments.ready for opening race next weekend.
