StopTech ST-40 BBK 355mm — BMW M3 / M4 (F80/F82)
Verified fit
2014–2020 BMW M3 (F80) · 2014–2020 BMW M4 (F82 coupe / F83 vert)
Description
StopTech ST-40 front BBK for the F80 M3 / F82 M4 sedan and coupe. Forged 4-piston caliper, 355mm 2-piece floating rotor, OE pad shape (so you can run any pad in the StopTech / Hawk / Pagid catalog).
Why this kit instead of the Brembo GT? StopTech is the answer if you want OE pad shape compatibility (huge for track-day pad swaps) and a slightly less aggressive initial bite — more linear modulation through the pedal, easier to heel-toe consistently.
