Has anyone installed lowering springs on a G35 before? I just bought the Tein Stec springs and I'm planning to install them myself. I've noticed that the rear suspensions are not coilovers like the front. I've never replaced a suspension where the spring and shock are two seperate pieces. I have experiences with coilover-type of suspension, but not those on the G35's rear suspension. Any tips or guides would be appreciated.

Thanks
