Do you really need those expensive spring compressors to do the job? What about the normal strut spring compressors you can buy at any auto parts store. I used those to change some struts in a VW. I realize the coil springs on my Benz are much larger but that seems like a fortune to spend. Again, safety is more important than saving money but are these tools really necessary? I would appreciate any comments as I plan on replacing the shocks on my car - '85 300D and would also like to do the coil spings.
