Thanks everyone, I am thinking a half coilf from the front and rear is probably the way to go, then balance it out with pads down the road. If I end up needing the arms, so be it, but if that is the case, I am going to cut a whole coil later when I add them

I am going with 19" AMG wheels all the way around but maintaining the factory height, going much wider.
So it is a half coil from the front abd back, it has nothing to do with the linear length of the coils and matching that measurement then?
Also, I basically have a metal shop at my disposal, not sure exactly what is there tool wise, but I would think he has most everything, what is the best method for cutting these bad boys? Les mentioned lube and a slower cut, what type of lubrication do I use? I have never cut springs before (I am sure you could tell LOL) and only want to have to do this once....
THANKS
