How can I identify which springs that I have on my car? I bought the car used and I am not sure if it has the stock springs or not. Can I measure the spring wire diameter to determine the rate? How do the aftermarket springs, such as RSD, work?
I ran the car for the first time yesterday. It was on a tight medium bite carpet track with rubber tires. The chassis was dragging on the motor side. I am thinking that a stiffer spring may help, but not sure. The ride height was about 4.8 MM, which may be a little low. Any ideas will be appreciated.
Thanks.
