John Cooper Works (JCW) is a company originally founded in the year 2000 by John Cooper, the legendary racing car constructor and tuner responsible for, amongst other achievements, the Mini Cooper.

When John Cooper passed away very shortly after creating JCW, management passed to his son Michael Cooper. JCW continues the strong motorsport heritage of the Cooper bloodline, producing tuning parts and accessories for BMW's new MINI.

BMW Group considered JCW to be "strong enough to be developed as a good subbrand" and bought out the company in January 2007.

JCW Tuning Kits.
Mini Cooper.
The first ever JCW kit was a 126 bhp upgrade for the MINI Cooper. The kit consisted of the following components:
- Flowed and ported Cylinder Head
- Air Filter
- Cover Injection Tube
- Uprated exhaust (cat-back)
- ECU remap
- Decorative Emblems

Despite its price tag of over 2000 Euros, this kit only offered a power increase of 11 bhp, a sportier exhaust note and a crisper throttle response. The main advantage was that these improvements, though fairly minor, could be made to the MINI Cooper without jeopardizing the factory warranty.

Mini Cooper S.
The first JCW Tuning Kit to be made available for the Cooper S was a 200 bhp upgrade for the Cooper S. Released in 2003, the kit consisted of the following components:
- Uprated cylinder head, gas-flowed and ported
- Uprated supercharger, faster-spinning
- Uprated air intake system and air filter
- Uprated spark plugs
- Uprated exhaust system
- Remapped ECU
- Decorative badges, individually-numbered engine plate and certificate signed by Mike Cooper.

At the time, the kit could not be factory-ordered, but had to be retrofitted at a MINI dealer, but from late 2005 the Cooper S could be ordered with the upgrade straight from factory.

In 2005, an additional upgrade was launched that increased power even more, to 210 bhp, by installing uprated injectors and again remapping the ECU.

A "JCW Sound Kit" was made available at the same time, consisting of the cat-back exhaust and the air filter, giving a sportier exhaust note and a 3 bhp power increase for around 1100 Euros.

Mini Cooper S R56.
In 2007, MINI released the JCW tuning kit for the new "R56" version of the car. This new version now being turbocharged as opposed to supercharged, the kit itself is very different to that of the previous Cooper S. Consisting of an uprated induction system, exhaust and ECU remap, this kit ups power 17 bhp to 192 bhp. Torque is up 10 nm to 250nm (270 nm with overboost). Acceleration from 0-100 km/h is now 6.8 seconds, and a top speed of 232 km/h is now possible.

According to Mike Cooper, a MINI fitted with this kit will be "the fastest MINI ever" above all due to the extra torque and in-gear acceleration, which in certain driving situations will be even faster than the 218 bhp MINI JCW GP.
