17+ Honda Civic Si Sport Springs 'Spec R' by Swift

Swift made Sport Springs keeps the quality ride you get from the showroom, and adds improved handling and lower ride height for driving enthusiasts and style minded drivers who demand only the best.

From HPDE events to SCCA competition, Swift Spec-R Sport Springs are made for the track enthusiast looking to take their vehicle to the next level.

Swift Spec-R Sport Springs were engineered with 3 characteristics in mind. Modified ride height compared to Sport Springs to maximize optimal suspension geometry. Further increasing the spring rate to enhance overall performance. The increase in spring rate is based on the upper limits of the vehicles factory shock valving. Maintaining optimal comfort level for street use.

Spec R springs are wound with the same engineering and material as our sports springs. With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sports springs.

Quality springs with good performance but wish they were a tad lower

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.

Modest drop, handles so much better

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!

Perfect Springs

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.

Good on my 2017 Hatchback sport

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.
