For F20 and F21 LCI 1 Series (2015-2020) owners who want a clean, OEM-plus rear end without the £££ of M Sport or full carbon fibre.
Exact fit for pre-facelift and LCI bumpers - no trimming, no drilling, no 'nearly right'
Made from CT Carbon’s signature ABS plastic: gloss black throughout, UV-stable, impact-resilient, and lighter than OEM thermoplastic
Popular with fast road, show car and daily driver builds - not track day spec, but won’t yellow or crack by year two
