I agree, I used my set of Autozone compressors on the driver side of my 240D, although it worked, with the nut facing down, my compressors were on the brink of stripped threads. These MB springs are of top quality and are thick and heavy duty (well.... its an MB, what do you expect? LOL) but anyways, it was hard to get the hooked ends into the coils, I had to pry them apart to fit the hooks in. After nearly stripping the threads, I said "Screw this"..... I was going to replace my LCA bushings, just for the hell of it, but after that crap, I took a closer look at the bushings and decided they werent really that bad anyways. Also, compressed springs are deadly if the compressor breaks. I was working on a chevy truck once when my clamp type compressor broke on me, and it sent the LCA of the truck into the concrete and shards of concrete flew out across the shop. Springs are NO JOKE!!!
