I needed a new auxiliary belt for our R53 Mini Cooper S. I contacted Oli at Oranje for advice as the Mini has a 15% reduced supercharger pulley. He responded within hours, I placed an order which was dispatched without delay. The updates on the parcel tracking were excellent. The tensioner kit has been fitted and is working fine. Just a heads up please keep a regular check on your car's belt, as my shredded rather than snapping. It then tried to rip the idler pulley out of the block , damaging the thread. Major work was required to gain access to repair the thread. The service and advice from Oli was superb.
