The 1 Series is our biggest collection by product count, with parts stocked across five distinct shapes — E81/E87, E82/E88 (plus the 1M), F20/F21 pre-LCI, F20/F21 LCI and the current F40. Here's how the range breaks down.
Front Splitter — Deepest Choice on the F20/F21
The F20/F21 has the widest splitter range we stock for any model: separate M Performance-style splitters for pre-LCI (2011-2015) cars in gloss black or carbon fibre, standard gloss black and carbon options for the same era, and dedicated LCI (2015-2019) splitters in both finishes. E82/E88 coupe and cabriolet owners get their own splitter in gloss black or carbon fibre.
Rear Diffuser — F20/F21 Only
Diffusers are the F20/F21's strongest category: lip and valance styles, an S-badge variant, and a rear shark fin diffuser, each available in gloss black or carbon fibre and split by pre-LCI and LCI fitment. E82 coupe owners can also get a rear diffuser with integrated LED detailing.
Rear Spoiler — Every Generation Covered
Roof spoilers are stocked right across the range: E81/E87 in gloss black or carbon, E82/E88 1M-style boot spoilers, F20/F21 pre-LCI and LCI roof spoilers (including an M135/M140-inspired shape), and a roof spoiler for the current F40.
Side Skirts — F20/F21
Gloss black side skirt extensions are available for F20/F21 models, finishing off the lower half once the splitter and diffuser are fitted.
E81/E87 vs E82/E88 vs F20/F21 vs F40 — What Changes
These are four different bumper and boot shapes, so parts don't cross over between generations. F20/F21 also splits into pre-LCI (2011-2015) and LCI (2015-2019) fronts, which changes splitter and diffuser fitment specifically — check your exact year before ordering.
