Good news - the noise is just the backet on the heatshield. New one on order so should be a cheap fix. Horizon also couldn't find any problems with the clutch, it must just be me being paranoid or the new slave cylinder bedding in.
REALLY bad news - my suspension is fucked. Pulled off from the house this afternoon and noticed a loud banging while driving down the road. Pulled over and noticed that the pax rear tyre is almost touching the arch. There's also VERY little body movement over this wheel. Somethings REALLY wrong. Will see if I can arrange a garage to pick it up Monday.
