did you end up gettin the K Mac springs ?
Im seriously looking into this if they are good to deal with. im looking drop of 3.4" front and 2.75" rear
I'm not sure if you guys know this or not but if the spring has dead coils they can be safely cut, in fact a LOT of people in the sho community do this. There is a spring made by moog for a taurus wagon and a lot of showners use these springs accept they cut 1.5 or two dead coils out to get the stock ride height. The spring is almost as good as any aftermarket accept it costs 30$ ea. Currently i cut half a coil on a stock progressive spring on the sho up front and got the drop i expected.
what i mean by dead coils is the coils that dont get used the ones taht are close to each other. the pic bellow will show better what i mean. The coil on the verry left has the most dead coils.
So if you guys are buying custom springs jsut tell them to make like 4 dead coils or more so you can adjust the ride height at will safely.
