Cobras don't have much suspension movement and should be somewhat stiff in order to handle well. You can't tell the spring rate by the diameter of the spring. Get under the car (jacked up) and spin the spring around to check if there is a brand name on it, then look for colored paint marks which will tell you the spring rate per the mfg's code. There really isn't a race or standard spring, just spring rates. Just remember, it's not gonna ride like a family car, it's basically a race car for the street.
