Finally got around to installing the Tein H-tech springs yesterday....and figured while I had the wheels off I would paint them too. The spring install was SO easy, took just about 2 hours to complete. One mistake that I made was not marking the position of the rear top-hat so it would line up easily when re-installed, but it was an easy fix that only took about 10 minutes. Aside from that, everything went really well, and I am VERY pleased with how aggressive the stance is.
It's supposed to be nice today so I will get it washed, clean it up nice and take some pictures to post.
