READ the warranty PDS, as i deal with it allot in my work, generally any aftermarket parts are not covered by warranty, depending on the conditions this does not usually VOID a warranty however if you have a failure due to your modifications then you are out of luck.
this is up for interpretation, not your interpretation btw so be careful.
but if you fit different brakes and your ECU dies, then its not going to be linked is it.
