Spring calculation help please !!!!!
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
