E21 316: Spring Chop Chronicles 2 - Cutting E21 Springs Explained

Cutting car springs at home - a good idea? Well, no. We've all heard the story about that guy who chopped the springs on his Mum's Nova SR and ended up on his roof. Most modern springs are tapered at either end to hold them into the spring-pan and this means that cutting them changes the design and they won't fit. If they do they won't work properly holding up the weight of the car. Your average knowledgable bloke will say "Ah, yes, but they will work if you cut them right!". This is not the case. You can never cut tapered springs to work right, period.

If you own an E21, or one of most other classic cars, then you will likely have the old style 'pigtail' springs that do not taper at either end. They're just a coiled spring, which end in a point and sit in a groove in the spring-pan top and bottom [2 in the pic below]. These CAN be cut shorter and still work - as long as they are cut right.

Why do it?
You want to go lower with your car, but a spring-kit isn't available to go as low as you want. You don't want to fork out money for lowered springs.
