NOW... since they are doing bidness commercially, they are exposed to liability, which makes them play it super-safe to limit exposure. Not only that, they are in bidness to sell springs (I'm not sure why they put out the truth about home cutting them... maybe they are just that honest?) I'm not in the biz, but even if I was, I stand by my heat-reshaping of the spring seat. Think of it, they state that heating above 400deg = annealing, and annealing = steel too soft to support the vehicle. Well look at that last coil on the square ended spring- that last coil is basically sitting there and it ain't flexing... if it is flexing, it's only a wee percentage as much as the coil above it and the others above that. All it has to be is strong enough to keep the spring seated squarely, not bear the weight of the vehicle for the entirety of that last coil.

Two friends are rebuilding a 240Z, installing a roll cage, fiberglass hatch, dynamat, new wiring, transmission... the works. I'm in their garage recently and tell them I am considering lowering the car. He says I should cut the springs. I say I can't reverse it. He says, "but you don't want to reverse it." She's just looking at me as he suggests that buying replacement stock springs would be much cheaper than buying aftermarket lowering springs, and I think of Frank Lee again. I have no idea if I'll do it, Frank, but it's amazing how much space in my head you are renting for free when it comes to this idea!
Thanks for the link.
