Call any other spring source or hot rod shop and they might have 4 Mustang II different coil springs. 4 would be fine if all cars were the same and if everyone wanted their car to ride the same and sit at the same height.
Well, surprise, not all cars are the same and everyone has their own ideas on how their vehicle should sit, ride and handle. So to help these wise folks, we have developed 23 different Mustang II coil springs.
With a selection of 23 springs you are able to get your ride just the way you like it.
With umpteen years of doing this stuff and a some help from our colleagues in the building business and some of you fine people, we have created a chart giving our recommendations of what spring to start with.
