Can anyone help with spring calculation
 

I have a mid 60's AC Cobra replica and am using a mid 90's 8.8 rear end. Can anyone help me or better yet, teach me to figure out what spring i need. I have all the facts IE: the left rear wheel scales at 669 Right read wheel scales at 682 for a total rear weight of 1351, I am using a stock ford geometry for this set-up with the upper and lower control arms at the stock dimensions I need a spring that is ( I assume) 250 lb.s when the spring is compressed 1" (or 10" overall compressed length for the perfect ride height).
Help ME!!! Please!!!, why can't anyone figure this out there has to be a spring manufacturer that can help with customs.
Sincerely,
Mick

i can't help you, but have you called any replicar builder's tech dept?
you could also try Maximum Morotsprots, they are mustang suspension pros, and raced a gutted fox body car. the geometry will be very similar and the weight won't be so far off that a good spring rate can't be determined.
what do you want to achieve with this car? is it to be a track racer, a drag car, street car, all of the above????
250#/in rear springs in my 3200# fox were too soft for week-end track duty,but not too choppy for the street.

"decent ride" is relative to each persons own backbone. if you are looking for street / drag use. 250#/in would not be too stiff. if you want a road track car theyare probablytoo soft.
