BMW 4 Series F33 (2013–2021)

A sensible order for preparing an F33 convertible for the track is brakes, then tyres and alignment, then suspension. Brakes are also the largest group here: EBC and Hawk pads above all, plus Ferodo, Pagid, PBS and DBA, spanning fast-road to race compounds. EBC and DBA vented discs sit alongside, with a HEL braided line kit and Girodisc titanium backing plates. Renew the fluid at that point. TTF sells neither tyres nor alignment work. For suspension, KW coilovers lead, including DDC plug-and-play, with H&R, ST and AP, plus B12 kits from Bilstein or Eibach and lowering springs. Build years: 2013 to 2021.
