Suspension systems that not only transform the stance of the vehicle but also maintain ride quality and improve upon handling are what Dinan suspensions are known for. This is accomplished by pairing springs sets with bump stops, spring perches or both to maintain suspension travel resulting in a smooth ride while also improving mechanical grip and handling. This is what makes Dinan suspension systems unique. While we are able to sell each component separately it is highly recommend that both the spring sets and the supplemental ride quality and handling kits are used in tandem in order to maintain the Dinan quality standards our customers are used to. Experience the Dinan difference with this combination and enjoy the ride it provides. Dinan's Performance Spring set for the F22 M235i provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the M235i by a 1/2" in the front and 5/8" in the rear for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot peened for stress relief to last the life of the car. The Dinan performance springs provide a noticeable improvement in grip, for high speed driving situations that will inspire confidence in your car's capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at low speeds up to the top speed of the vehicle.
Any tuning/performance-based mods/work/quotes and products are strictly for off-road and motorsport use only. Performance mods/certain exhaust systems will cause your vehicle to fail the MOT emissions test, therefore rendering the vehicle unroadworthy and illegal to be used on UK roads. PLEASE BE AWARE – Sports cats can NOT legally be installed on a vehicle for use on a public road that was manufactured after 1st March 2001 unless Type ECE 103R is approved (identified by ‘103R’ in the exhaust product title). Fitting a Cat/Cat Bypass or GPF delete/bypass to a vehicle that is to be used on UK roads will cause the vehicle to fail the MOT emissions test, therefore rendering it unroadworthy and illegal to be used on UK roads. Please note that UK regulations specify that the nearside and offside front door windows, for which the driver uses for forward vision, and when using external rear facing mirrors, must permit a light transmittance value of at least 70% ( for motor vehicles first used on or after 1st April 1985), with the front windscreen permitting a light transmittance value of 75% Please note that factory fitted windows are already tinted and by adding additional tinting, this may result in vehicles no longer being compliant for Road use.Read more
