Perfect Light Drop

Tracked on them a week after install. Light drop, very functional. Maintains/lightly improves ride quality and performance over Stock/OEM.

Had this on my previous car as well!

Spectacular!

Spec R springs is the best mod so far! The ride is way smoother than stock springs believe or not, back roads are a must almost every drive lol. Engaging is an understatement. Extremely recommend spec r springs!

Ps. While this is not a paid review, I wouldn’t mind a discount on the cobra cai (race maf) lol 😅 pls map fellas

Very nice

The drop isn’t insane and unmanageable if you daily your car BUT visually pleasing and noticeable. Definitely noticed some driveability changes which were super cool; taking turns seems to be a little more tight and smooth. Clearly you also avoid messing with your active damping system as well. I would recommend these springs to someone that wants to add a lil something to the aesthetic of your civic without having to avoid speed bumps etc.
