As one of the most capable of super-saloons, the M5 is bought by many petrolheads that seek near-supercar levels of performance in a package that can be used every day. Fulfilling its brief perfectly, the M5 is a hard car to fault, but for the many owners that wish to add a little aural excitement into their daily commute – not to mention some welcome extra power and torque, this latest Milltek system will be the ideal enhancement.

Milltek’s R&D team took an innovative approach when designing this system, following hours and miles of dyno and flow testing. The stock BMW exhaust system uses an 80mm diameter in most places, but features many ‘pinch points’ throughout its course, all of which dramatically restrict gasflow. Using the latest CAD analysis, Milltek engineers discovered that dropping the entire system to 76mm, but using precision CNC mandrel bends to maintain a precisely consistent diameter, flow rates – and therefore power – could be improved throughout the rev-range.

This isn’t the only bit of smart thinking from Milltek, however. By using the OEM BMW vacuum control valves, which integrate perfectly with this new exhaust, full factory functionality can be retained, including the dash-switching operation between exhaust modes. The result is a car that can purr quietly and discreetly to work in the morning, yet create a racecar soundtrack with pops, crackles and over-run burbles on the way home. On a car like the M5, which needs to be many things to many people, it’s the ideal compromise.

As with all Milltek systems, quality is the watchword throughout. Aerospace-grade, non-magnetic stainless steel is used for the entire system, with hand-finished welds and precision jigged construction. The result is an exhaust that fits as per OEM, but with a longevity and soundtrack that are anything but.

The system is also awaiting full EC-approval so meets or exceeds all requirements for sale in those countries which require TÜV or similar Type-approval.

The quad GT90 tips are available in either polished, brushed Titanium or Cerakote black.

Lowering Levels:
Front: 5-30mm
Rear: 5-25mm

A KW Height Adjustable Coilover Conversion Spring Kit is the ideal solution if you want to keep your cars stock dampers but still enjoy the benefits of adjustable lowering like you would get with coilovers.

Whereas a normal spring kit generally offers a fixed amount of lowering, KW’s coilover spring kit comes with it’s own adjustable spring seats/perches which replace the fixed factory items allowing the lowering level of each to be finetuned individually.

Taking only a little more time to install than a lowering spring kit (perhaps an extra hour to finetune the lowering amount) this kit replaces the stock, non-adjustable spring seats/perches and generally includes springs precisely matched to the factory dampers, adjustable perches/seats, bump-stops and dust-covers.

Unlike conventional coilovers which replace the adaptive dampers or an expensive electronically adaptable coilover set-up this upgrade goes straight onto the factory adaptive dampers.

Many of the springs provided are progressive rate. Progressive rate springs are ideal for fast road use. The spring is softer in the middle so for small compressions (e.g. small bumps and imperfections in the road) they remain compliant but firms up as it compresses further to provide excellent body control and taut, predictable handling through corners. KW specifically select the best spring for each application on a kit-by-kit basis.

Each kit is carefully tuned to match the factory dampers on the car it is intended for. These are proving to be a popular upgrade on high-end performance models with adaptive damping from the factory.

As with anything KW make, these springs are manufactured to the highest standards. Each part number is individually TUV certified (copy of certificate can be supplied upon request by us or KW) for peace of mind and to meet local legal requirements. Springs are manufactured from Silicum Steel with a tough weather resistant coating.
