Dinan's Performance Spring set for the F85 X5M and F86 X6M provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the vehicle by a 5/8" in front and 3/4" 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 10% increase in stiffness to the springs will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also 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.
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
