To weld on springs or not

Thanks guys for straightening the welding bit out. You are correct. NEVER weld to a spring. Next time someone mentions it, send him here: http://www.eatonsprings.com/SpringWelding.htm
And here's some info on cutting coil springs http://www.eatonsprings.com/atqCuttingCoilSpringsCalculations.htm, if you go to our list of Tech questions, we have several covering the subject.
That being said, if you're going to buy new springs, just tell us all about the vehicle, and where you want her to sit, and we can make them for you. You won't have to go through all the calculations and comparisons. That's our job. We'll send you a set you don't need to cut.
