D2 Coilovers Sport HONDA CIVIC SI FA5/FG2 (USA) (06~11)

D2 Coilovers for the enthusiast car! 

This is a favorite of us and our customers! You won't find better kits that provide more performance and quality in this price range! We have installed these kits on cars that has previously run on more expensive and "exclusive" brand of coilovers and they have got better results from this kit. 

This coilover kit is perfect for those who are looking for coilovers for your street car but who also want to be able to drive some track days, with really good track times. 

D2 has taken the best from racing kit and the best from street kit and made this sports kit. You have the long stroke of the street kit, which makes it work great for street driving. The shock absorber is about 30% harder. The spring number is usually only slightly harder than street kit (10-15%) which gives a slightly over-dampened character (more low speed).

This makes a bigger difference between the adjustment levels of the shock absorber and you can easily find a good setting for your street driving. Increase the stiffness of the shock absorber and you can mount on R tyres and use it for trackdays. 

The car will be perceived as very stable, tight and with a distinct feeling in road handling without the slamming and extremely hard ride as it does on a racing kit. The height of the coilover can be adjusted steplessly by adjusting the lower mounts, providing a perfect reconciliation between the spring and the shock absorber regardless of the height of the car (unlike coilovers where the height is adjusted on the spring). 

The sport coilover kit has the top mounts from racing shock absorbers which means a traditional pillowball construction with a distinct feel. You can adjust all four shock absorbers individually in 36 levels. You then have the opportunity to balance over and understeer your car. You can have a normal mode that you can easily adjust harder if necessary.

The height can be adjusted steplessly by threading the lower mounting up or down on the shock absorber body. This provides a perfect reconciliation between the spring and the shock absorber no matter what height you have on the car (unlike coilovers where the height is adjusted on the spring).

Top Mounts:

(P): This top mount has a pillowball construction. It's standard on our racing kits. It gives a distinct feeling but lacks some of the comfort of which is found in P+ and R. This is usually camber adjustable. 

(A): On cars with A-arms construction in the front, the top mount is called A. This design is considered to be the best construction car design on cars, but is also more expensive to manufacture. Therefore, it is not so common on standard cars. The Camber angle is adjusted only on the link arm and not in the top mounts. 

(OE): Some cars have a special design in the top mounts which force D2 to adapt its top mount to the car's design, this lacks camber adjustment and is called (OE). 

See which top mounts that are available for your model under the specifications (you can see them under the Add to Cart button).
