BMW 1M Upgrades

Stage 1 - 355 bhp

1M Cobb Accessport

Using the Cobb Accessport V3, we are able to create custom mapping for your car. This is tailor made for your specific vehicle rather than being an off-the-shelf solution and allows us to significantly increase power and torque. The Cobb Accessport can also be used to live-read ecu data, scan and reset codes, datalogging and performance measuring. It will also allow you to quickly revert back to the standard map if necessary.

Stage 2 - 390 bhp

Stage 2 is a further ecu remap, combined with a more freely-flowing catback exhaust, but retaining the original downpipes. The 1M responds well to this change, allowing power to be increased to 395 bhp. We supply catback exhausts Akrapovic.

As well as significant power and torque gains the Akrapovic Evolution Line also provides a weight saving of 8.7 kg

There is also an Akrapovic sound kit available for the Evolution Line which can be specified separately and takes a further 2 hours to fit.

Please watch the video below to see Top Gear's Chris Harris drive his very own 1M, which we fitted with an Akrapovic Evolution Line and a sound kit.

Stage 3 - 420 bhp

For those customers looking for our complete tuning solution for the 1M we use the Akrapovic Evolution Line system with Akrapovic stainless steel downpipes. Coupled with a remap and a Forge Motorsport intercooler we are able to push the power output up to 420 bhp, which is 85 bhp up over the standard car.  Installing DE-CAT pipes is for Motorsport use only as the car will not be emissions compliant for road use.

Eibach Pro Spring Kit

The Eibach Pro-Kit springs help to reduce squat under acceleration by lowering the car's centre of gravity whilst giving a more aggressive look. This kit lowers the 1M by around 35mm at the front, 10mm at the rear.
