What mods are available to boost the horsepower / performance of my 2009 non "S" clubman? Which give the best bang for the buck, and will they void my factory warranty? Thanks guys! I'm new to this forum and minis too.

There's a few places to start, anything under a performance category will do the trick, there aren't a ton of things but there are some... not sure, but the Alta AccessPort might be compatible with 2009 Clubman's now...

 

It is but Adam said they don't have any Justa programs.

 

Thanks for the start, guys! So I cannot find any aftermarket turbos or superchargers. Is that correct?

 

Anything is possible with enough time/money.
