Preparing for our next performance tweak, we will be fitting a Cooper S (R53) throttle body to our Mini (R50).  Unfortunately this is not a direct swap and an adaptor plate is needed.

We came across a post on Facebook by Kieran who sells a fully CNC`d adaptors and he did us a fantastic deal to support our Mini..  This arrived on Friday and the quality is superb…  We will be fitting this next week hopefully.  Please see Kieran`s information below :-
