Tj I'm holding off on a deep dive review till i have a few more miles on them. So far build quality is excellent, and my shop liked them very much. Supposedly so much so, one of the employees was swearing on buying a 370+tein springs
. Initially i was worried about the rear drop, but i forgot i had removed my spare and all my tools/fittings etc. After putting everything back in it seems to have evened out some with the front. Also I'm hearing these springs sag a good bit. In the end expect over a 1" drop all around. Some say closer to 1.4 in front, and 1.2ish in the rear. So far I'm very satisfied with ride and build quality.
For more pics check out my370z album on my profile. I will update in a week or so once sag has come down, and i have a better impression of the ride.
Advertised drop is .87F .75R with a max of .05 sag. But as other 370z + tein spring owners have commented, this is a very conservative number.
