  1. Mystery Diff Fluid. Amazeballs. RDU over heating with slicks... any solutions???

    Focus RS Racing
    So, I broke the front axle on my GTR and my MPSS are toast on the RS. I bought some Ferrari Challenge Pirelli slicks for the RS tomorrow, because I have issues... I am obviously worried I am going to cook the rear differential faster than normal. I believe I have heard of some fluid options...
  2. RDU lifespan

    Focus RS Discussions
    All clutches eventually wear down. Since the RDU of the RS is clutch based, I'm wondering that how long I can enjoy the ride before it gives up. Kind of sad to think about it =(
