I was looking at a set of Topspeed coilover. I asked the sales guy what the spring rate was. He said it was on the spring, but didn't know how to read it. It was something like:

700.250.01 or something along that line. What do those numbers mean?

The first number is usually the length of the spring, in this case 7 inches. The second number is the diameter of the spring; 2.5 inches. The third number would typically be the spring rate. I don't know what yours is saying though. On my 350lb ERS front spring, the numbers read 700.250.350. And on the rear ERS spring, it read 150(mm).64(mm).53 (which happened to be metric numbers... ack!)

If they cant even tell you then they probably arent worth buying! Im sure if you called ground control theyd tell you spring rates, lol.
