BMW M4 Upgrades

On this page you'll find our current available performance upgrades for the sublime BMW M4 which currently include the Akrapovič exhaust systems and brand new Litchfield ECU remaps . This list is not exhaustive as we have plenty of exciting products in development which will be announced shortly. 

 

  

Litchfield BMW M3/M4 Springs & Eibach Spacers

Extensively tested on road and track, with input from WTCC Champion Rob Huff, our superb lowering spring kit for the M3/M4 improves the grip and handling of the car whilst retaining the ride quality. Combined with Eibach spacers, the wheels now perfectly suit the arches. If fitted here at Litchfield, we also re-align your M3 or M4 to our own settings.

BMW M4 ECU Remapping

As soon as our state of the art Maha dyno had been installed we put it to good use developing our ECU  remap for the BMW M4. The remap is the culmination of extensive testing and has been designed to take advantage of the benefits provided by the Akrapovič Evolution exhaust system. The result of this potent combination is 525bhp which completely transforms the car, sharpening throttle response and improving the overall driveability. The graph to the right displays the improvements when fitting the Evolution Line alone versus the Evolution Line when combined with our remap.

These maps are available for installation, if you would like to book your car in with us don't hesitate to get in touch 

Remus Sport Exhaust

The Remus cat-back exhaust system is now available to order for the BMW M4. The Remus system features an x-pipe which removes the front silencer along with the secondary cats. The rear silencer includes 2 integrated valves which are controlled by the original servo motors. 

The system features a shot-blasted finish along with a choice of four different tail pipes designs. The system is available to order from our shop.
