Re: 2'' drop from cutting stock springs?
Quote:
Cutting 1 coil is about the 'limit' for height vs. ride quality change. Once you cut more than 1 coil, the spring rate does not keep up w/the now shorter travel dimension so the ride quality can suffer (it's a grey area). I always try cutting the existing coils if... a) I felt the ride was decent b) the vehicle was fairly square (one spring wasn't sagging more vs the other) c) I don't 'need' to save the original springs I have used aftermarket dropped coils on several applications where I needed a more agressive spring rate to compensate for the shorter travel range once dropped. Case in point, the above mentioned 350# spring was on a g-body Malibu. With 2" dropped spindles & 1-coil cut from the factory springs, the tires were constantly buzzing the tops of the front inner fenderwells. There just wasn't enough spring rate for the limited/decreased travel (<400#). I revised the set-up w/some 640# dropped coils & achieved the same ride height but rarely buzzed the fenderwells. The ride was comparable to a late model Z28 or Mustang. For these 60-98 GM trucks, I typically will trim 1-coil before paying for a generic aftermarket 'lowering' spring.
