One of our favorite upgrades to the R56 is the JCW Aerokit. And not only does it give the car a more aggressive look, but it’s actually somewhat functional in helping keep the car planted at very high speeds.

But it can also be a bit costly. So to give MotoringFile readers a helping DIY hand, we present you the official install guide PDF. While you’ll still need to order it and have it painted at a MINI dealer, the install is possible in the confines of your own garage.
