Customer Reviews
I've heard great things about Swift springs in terms of quality and performance, which is mainly why I decided to go with these springs over the competition. I agree with those reviews. I do wish they lowed the car a tad more. Still a noticable wheel gap with the Swift springs installed.
Not the lowest drop but very functional for a daily driver. Feels more locked in turns. Sport mode just a little bit bumpier. But very pleased!
Parts came sooner than expected and it great packaging. Installed them the next day and I can’t stress how much I love the ride. Perfect amount of drop too, not too low to the point where it could affect spirited driving.
I love the way they feel way stiffer then stock good height I daily my car doesn’t bother me at all would recommend To anyone who wants the stiffer more track feel
I installed these after work and they give the vehicle a good drop. Not too much but enough where you dont have to worry about Shox blowing etc but its esthetically pleasing. I cut my bump stops a bit and still feel a bit of bounce. I do recommend lowering spring silencers as the spring hits itself while parking and makes a soft clunk sound. This is common in lowering springs ive learned. Make sure to tighten everything and as they settle re tighten again a few days later.
