Home of the Red Headed Stepchildren of the 2nd gen Camaros!
This is a work in progress till I can figure out this CSS and tables stuff.
I wanted to make a chart similar to the one used over at this Monte Carlo Site. This is to compare the stock springs of my car (AC/75-79/V8) to other possible springs. The stock 329 lb spring held up 2310 lbs at its install height of 10.5 inches. This shows me at what height the other springs will hold a similar weight. For a one inch drop over stock, at an approx. 400 lb rate, the 5610 would be a choice. For 3/4" drop, the 5642 might be used.

The 5610 was designed to hold up 1750 lbs at 11 inches. My approximate front end weight is 2310 lbs, so the 5610 compresses until it can carry that much weight. These are all very general guidelines and you would have to have an accurate measurement of your front end weight to be precise.
