Hurricane HMS2002 build thread

[HMS_Steve]

A lot of consideration went into the suspension design. We recognized a need for tunability and to accurately make changes you need to know where you started. In a car that weighs roughly 2500 pounds, a good wheel rate for street driving would be 200 to 225lbs. For track days and racing you would want to target 275 to 300lbs as a wheel rate. With some measurements taken from our suspension components, we can accurately calculate the needed spring rates. The Hurricane roadster would need 500 - 550 pound springs all around on Dean's car for street driving but that's not his style. We decided to use 800lbs in the front and 750's in the back from Hyperco to get a wheel rate that is just slightly under the 300lb rate we targeted. We can do the balance of the suspension tuning with sway bars. We will post more on the sway bar math as Dean gets to that point in the build. For those of you that would like to check the accuracy of your spring rate here is a calculator that makes it fairly simply.
