I have been starting to work on my Mini S and I need tips on what will make it better, and also so I don't destroy it. lol
So far I am planning on switching out my stock pulley in my supercharger with a smaller one. I also am going to put a new exhaust and cooling intake. I will also need a better suspension. I just need to know what more can I do to make this a Mini that no one would **** with!
Any tips would help!

 

You can also put in a crank pulley and an aftermarket intercooler for the supercharger. Those will add few more ponies under the hood. Good luck!

 

im not sure if your still looking for upgrades but try minimania they have packages that put you around 300 hp, and there are videos for each upgrade system
