Forming a key component of the mountune Clubsport range for the Mk4/Mk4.5 Focus ST is our bespoke brake upgrade consisting of 6-piston T-6066 forged monobloc calipers and a grooved 355x32mm FH25 cast carbon steel disc-bell assembly.

    Mk4 club sport break kit

    I've used mountune for all of my performance mods and fitting service. Always been superb. This time I received the break kit and had it installed by someone locally. Well two days later I could hear a clunking kind of cracking sound on reverse breaks and forward breaking. Didn't sound good took it back to the fitter and got the car back ? Same issue. So I went to Mountune's which is a round trip of 5 hours . After so much stress these guys went above and beyond to fix the issue. Bearing in mind it wasn't down to the kit, it was down to the previous fitter . They diagnosed the issue after two attempts and I'm sure the technician missed his lunch hour to fix the issue . Excellent customer service and a massive thank you to Shaun and the technician I forget his name . I was more than happy to pay for there time . Shaune said there is no charge your custom is valued . How nice was that . As for the break kit it looks beautiful and in normal driving feels like every day breaking but at high speed it feels like my break s have been on steroids much strong
