Ok. I own a 2011 mini cooper clubman non S. The car is beyond sentimental to me so I’m not willing to trade it for an S. I want to mod it to high hell more than anything and I know thats gonna be a ***** to do. Im seeking all ideas and advice to make her a beast and I’m willing to put in all the work necessary. Currently I’ve installed a K&N Cold air intake and thats it :( I’ve been digging around forums for advice but I’m either terrible at research or theres really nothing so now Im here

 

There are header options available for the Justa engine cars, and cat-back exhausts, too. Since you have an intake, next step would be header and exhaust. After that, I would go all out on the suspension. Should have a pretty fun car at that point.

 

The first two mods I would do for sure are the powerflex engine mount as it will reduce the engine slop and help get the power down, plus it is on sale and easy to do in 10min.

Then of course a rear sway bar as that will improve the handling more than any other mod.

After that I'd look at suspension, brakes and such as all those will be bolt ons.
