A lot of people commenting that the spring clamps are for removing the springs - this is not the case, the clamps shown (I'm as surprised as you are) are to remain in the car, to lower it. They're labeled as "lowering clamps" on the packaging. Spring compressors are much larger, so you can clamp more than just one spiral of springs. As a side note, most auto parts stores will let you rent springs compressors for free, if you're ever in need. Have a great day everyone!
