DIY: 370Z Lowering Spring Install

dmboye01

Thanks for the write up as well, made the job a breeze. I have been lurking on this forum for about two years now, decided to finally post.

This past week while I was getting my stock rays powder coated and I was already up on jack stands I decided to go ahead with the Swift swap.

Some words of advice fwiw:
-Borrow someones compressor (as large as possible) and impact wrench. I have a 30gal tank and 800ft lb impact and it still took about four tanks of air each to compress and de-compress each spring. I cant imagine doing this job without air tools. The passenger side lower strut bolt would have been almost impossible to remove with just hand tools. Possible, but not fun.
-If you don't know anyone with air tools just go buy them from a big box store, use them, then return them...Unethical, but an option.

I did the entire job over two days, maybe 1.5 hours the first day to get the struts and back springs off the car. Then 5 hours the second day to compress and swap the springs and then install back on the car. The second day would have probably gone faster had I not been waiting on air pressure for so long.

I threw in a pic of pre-20mm spacers and springs for reference.

Thanks again for the DIY! This is one of the most informative forums I've ever read.
