Anyone know where I can buy swift springs in the US. Or what springs are ~3.75" OD? I am looking at buying some Ohlins but the front spring rate is too high for the street. The guy keeps giving me the OD but not the ID (which is Eibach gives for there ERS). I am interested in the Ohlins and they are a good price but dont want to be stuck with something that is not driveable on the street.
