So I just put on the Tein S-Spec springs. They are amazing! So firm, and cushy, and bouncy. Gave it a good 1” or 1.5” drop all around (Didn’t measure it!) Really sport feeling but oem too. Definitely gave it a stance. Very happy I went with them! The project was kind of a bear, especially with the back mount bolts being only reachable with a small box wrench. Overall I’d give it a 7 or 8 on the difficulty scale as far as install goes. Be prepared to rough it a little and solve problems and correct mistakes.
