Rev9Power 2014-2015 Honda Civic SI Hyper-Street II Coilovers suspension upgrade, which features mono-tube shocks with 32-way adjustable rebound settings. The Coilover have full height adjust-ability, which can be adjusted by twisting the lower bracket, instead of compressing the spring. By using Mono-Tube shocks, the shocks provide a larger capacity of oil and gas. Thus providing a better ride compared to lowering springs and stock shocks combination. The springs we provide are rated specifically to help improve the handling performance. The 32 clicks of valving will allow users to fine tune the rebound force setting, to ease comfort in the ride. By shortening the pitch distance, the independent spring tension and fully adjustable lengthen shocks will allow a nice drop in height, without sacrificing the comfort.
