hi i am planning on taking my sporty for a suspension lift at the end of the month if everything goes well with the finances.the point is that i did some shopping around here in south africa and came across a guy who does stretching of the coil springs then afterwards does the hardness treatment again to keep th strength of the coil and the ride quality in our currency it is R800 for front and back and they do all the stripping and putting back together.i think in your currency it would be something like $100 i don't think it is to bad for a 2" lift.
