Dinan’s adjustable coil-over suspension system is a quality entry level kit designed to satiate the dizzying possibilities of drops and aesthetics the consumer is looking for, while also providing improved performance. With a noticeable reduction in body roll in addition to a reduction in dive under braking and squat under acceleration the vehicle will perform better to go along with its improved stance. Dinan’s design implements threaded collars to allow the user to change the ride height and utilizes shorter bodied, custom valved, struts/shocks to maximize the lowering potential. The springs combined with progressive bump stops, struts and shocks increase travel and allow the car to be lowered aggressively to the owner’s desire, however, a 3/4" drop (1/2" drop on Audi RS5, S4 and S5 applications) in the front and rear is recommended to retain a civilized ride.

While aimed at being a cost effective solution the quality of the components is not indicative of the stellar price point. With heavy duty struts, twin tubed Dinan specific custom valved shocks with hardened chrome piston rods, and shot peened springs, the moving parts are designed for long lasting durability. You can rest assured that the Dinan suspension will perform superbly just like the day it was installed for many miles thus making the value proposition second to none.
