Eibach's rear anti-roll kit for the 10th Gen Civic Type R includes everything you'd ever want to stiffen up the rear. Featuring a subframe brace to provide even more rigidity, it also includes the sway bar, billet aluminum bushing brackets, polyurethane bushings, and rear end links. The 10th Gen Honda Civic Type R is a great handling vehicle but the Eibach kit will take it to the next step.
You can also buy the parts individually.
