BMW M3/M4 (F80/82) TUNING
Our BMW M4 demonstrator was amongst the first in the UK and we’ve been putting it through its paces at the Nurburgring and Silverstone. Whilst the standard performance is excellent we knew we could develop the car further.
As one of Akrapovics’ leading dealers we were delighted to receive the UK’s first Evolution exhaust system for our BMW M4 demonstrator. The quality of Akrapovic exhausts is always exceptional but the M4 system in particular is exquisite; it is even available with its own dry carbon valance to compliment the quad carbon tail trims. It gives the M4 a much deeper more menacing tone and full throttle sounds superb.
At the same time as fitting the new exhaust we also took the opportunity to install our lowering springs before heading over to Silverstone GP circuit for a thorough testing and were fortunate to have our friend, customer and World Touring Car Champion Rob Huff helping us and giving our technicians invaluable feedback.
Stage 1
Litchfield Performance Box - 500 bhp
Our most popular upgrade for the F80 series is the Litchfield Performance Box. It is an incredibly simple method of increasing the power of the car without compromising your peace of mind. Like our Mercedes-AMG A45 equivalent it's Plug & Play’ setup means it can be removed quickly and reverted back to standard at any time. The price includes fitting at Litchfield.
Litchfield ECU Tuning - 515 bhp
For those customers looking for a more complete solution we also offer a fully re-calibrated ECU, providing a significant increase in power and torque. This customised ECU mapping releases considerably more power than the tuning box and allows us to create a really smooth, driveable car. The ECU can now be tuned using the OBD port which offers fast programming or reverting back to standard.
Stage 2
Litchfield ECU Tuning with Akrapovic Evolution Line - 525 bhp
M4 Stock Exhaust:
M4 Akrapovic Evolution Exhaust:
We strongly suggest fitting the gorgeous Akrapovic Evolution exhaust system to the M3/M4. As well as delivering power gains throughout the rev range, the Evolution system also greatly improves the M3/M4's appearance and sound. A healthy weight loss of around 7kg over standard helps along with significantly improved exhaust gas flow. The exhaust uses original valve motor system so does not need extra wiring. We are able to just offer the Akrapovic Slip-on system, however as this involves cutting the original system, most customers prefer to fit the Evolution.
The price includes the slip-on system, evolution pipes, tail trims, fitting and ECU remap.

Litchfield ECU Tuning with Remus Sport Exhaust - 525 bhp
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 price below includes the Racing X-pipe, rear silencer (with stainless trims), fitment and an ECU remap to suit.

Stage 3
Litchfield ECU Tuning with Akrapovic Downpipe - 540 bhp
For use with any of the exhausts we offer, Akrapovic downpipe (stainless steel) and a full ECU map will give significant gains over just the remap or performance box and also benefits from a 3 kg weight reduction. Please note that this removes all catalytic convertors from your car. The price below is for the downpipe (not including a catback exhaust), fitted (based on 4 hours) with mapping to suit.
Litchfield Performance Springs
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.
Eibach Spacers
High quality hub-centric spacers from Eibach for the M3 and M4. 12mm and 15mm spacers supplied with longer wheel bolts and a set of locking bolts to suit.
Bilstein B16 Damptronic (EDC cars only)
For the next level of handling upgrade we would recommend the B16 Damptronic. It's aimed at those drivers who want a faster road setup but who also venture on to the track from time to time. Drivers can simply switch between 'Comfort' and 'Sport' modes at the push of a button, using the car's built-in EDC system.
- Sport mode for excellent driving dynamics and maximum power reserves in all situations
- Comfort mode creates smooth compensation for uneven surfaces
- Threaded body adjustable range of 20 mm at both axles, while installed
- Lowering of approx. 30-40 mm at front, 5-25mm at rear
- Road-tested by BILSTEIN under motor sports conditions and fine-tuned
- Surface coating using Triple-C-Technology for long-lasting corrosion resistance
- Quality sport springs made from highly durable material
- BILSTEIN mono-tube / Upside-Down technology, made in Germany
- German TÜV certificate
Michelin Pilot Sport Cup 2
This semi-slick tyre is aimed primarily for track use but is also superb on the road and is standard fit on the Ferrari 458 Speciale, Porsche 918 and Mercedes-Benz SLS AMG Black amongst others.

Performance Brakes
Similar to the GT-R, we have turned to our long-term braking partners to create a solution for the F80 series M3/M4. We offer the superb Alcon replacement discs assemblies with Pagid RS pads for track use or Ferodo DS2500 pads for the road. Prices are for the parts supplied only.
