The BMW 4 Series occupies a unique and compelling position in the BMW lineup — the two-door, open-top, and fastback expression of the 3 Series platform, liberated from the practical constraints of four-door packaging and developed into something with a lower roofline, wider track, longer bonnet, and a distinctly more assertive visual character. Where the 3 Series is the driver's saloon benchmark, the 4 Series is the driver's style statement — a car whose broader shoulders, raked roofline, and more sculpted surfaces make it one of the most naturally rewarding platforms in the entire BMW range to upgrade with precision exterior styling. At BodyKit.co.za, our dedicated BMW 4 Series body kit range is built to take that naturally compelling foundation and develop it to its absolute visual potential.

Our 4 Series exterior upgrade collection spans both major generations across all body styles — the first-generation F32 Coupe, F33 Cabriolet, and F36 Gran Coupe (2013–2020) including the F32 LCI facelift (2017–2020), and the current second-generation G22 Coupe, G23 Cabriolet, and G26 Gran Coupe (2020–present). The 4 Series body style family is the most visually diverse in the BMW range — the F32 and G22 Coupe's classic two-door proportions, the F33 and G23 Cabriolet's open-top character, and the F36 and G26 Gran Coupe's four-door fastback silhouette each present fundamentally different design challenges and opportunities, and every kit in our range is engineered around your specific body style's geometry rather than adapted from a shared template.

The headline transformation across our BMW 4 Series range is the M4-style conversion — one of the most visually commanding and technically accomplished exterior upgrades available for any BMW model in our entire catalogue. The M4's design evolution across the F82 and G82 generations represents two very different aesthetic philosophies, and our range covers both with equal depth and specificity. For F32 owners the F82 M4-style conversion delivers the wider front bumper, distinctive M-style quad air intake treatment, aggressive lower splitter, carbon fibre bonnet with M4-referenced venting, and side skirt profile of BMW M GmbH's celebrated turbocharged inline-six performance coupe. The F82 M4's design is widely regarded as one of the most cohesive and proportionally correct M car designs in recent BMW history — its understated aggression translates exceptionally well onto the standard F32 platform, and the result of a well-executed F82 M4 conversion is a car that is genuinely difficult to distinguish from the factory M4 at any distance.

The G82 M4 conversion for current G22 owners presents an entirely different visual proposition — the G82 M4's dramatically enlarged vertical kidney grille, wide-body front arch extensions, aggressive canard-flanked front bumper, and carbon fibre bonnet with pronounced power dome represent one of the most distinctive and deliberately polarising factory M car designs in BMW's history. For G22 owners who want the maximum visual statement that the current 4 Series platform is capable of delivering, the G82 M4-style conversion is unambiguous in its intent and unmistakable in execution. The G82 M4's dramatically wider front and rear arches are the defining element of the full wide-body conversion — pushing the G22's already broad visual width to a level that makes the standard car look narrow by comparison and delivering a stance that is equally at home on a track day and a Sandton car park. The G82 M4 Competition Pack aesthetic of exposed carbon fibre, shadow chrome accents, and gloss black trim is specifically referenced throughout our G22 M4 conversion component range.

The G82 M4 CSL and M4 GT4-inspired upgrades represent the most extreme tier of our 4 Series range — a motorsport-referenced exterior programme featuring fixed carbon fibre front splitter with canards, carbon fibre bonnet with NACA duct venting, wide-body arch extensions, full carbon fibre side sill blades, large fixed carbon fibre rear wing, and a rear diffuser with central exhaust outlet treatment that references the GT4 race car's aerodynamic architecture. For G22 owners seeking the absolute maximum exterior statement and a genuinely track-focused aesthetic, this is the definitive upgrade and one of the most dramatic BMW transformations in our catalogue.

The F36 and G26 Gran Coupe body styles receive dedicated treatment in our range — the Gran Coupe's four-door fastback architecture, longer wheelbase, and different rear quarter geometry require specifically developed rear bumper, diffuser, and side skirt profiles that flow correctly with the longer fastback body rather than the shorter two-door Coupe. Gran Coupe-specific M4-style conversion kits reference the M4's front end treatment while delivering rear styling proportioned for the longer body — a combination that produces one of the most imposing results in our entire four-door fastback range. M440i Gran Coupe-style upgrades for standard Gran Coupe trim levels are equally well represented and among our most popular F36 and G26 fitments.

For 4 Series owners across all models and generations who prefer a targeted upgrade approach rather than a full M4 conversion, our M Performance-style component range covers front splitter lip additions, M Performance-style side skirt extensions, rear diffuser inserts, carbon fibre mirror covers, M Performance boot spoilers, carbon fibre bonnet vents, and gloss black or shadow chrome kidney grille surrounds — all available as standalone upgrades compatible with standard, Sport, M Sport, and M Performance trim levels across both generations. The 4 Series M Sport bumper profile is specifically accounted for in all component fitments given the M Sport trim's prevalence in the South African market and the significant difference between M Sport and standard bumper geometry.

Cabriolet owners are specifically catered for in our F33 and G23 fitment range — rear bumper and diffuser profiles are designed around the Cabriolet's different rear deck architecture and soft-top housing rather than adapted from Coupe templates. The 4 Series Cabriolet's open-top character combined with M4-style exterior upgrades is a particularly compelling combination and our Cabriolet-specific fitments ensure the result is as cohesive from the rear as it is from the front.

All BMW 4 Series body kit components are manufactured from premium ABS plastic, fibreglass, or carbon fibre composite materials. Available in raw finish for custom painting, pre-painted to your factory BMW colour code including popular 4 Series colours such as Alpine White, Black Sapphire, San Marino Blue, Snapper Rocks Blue, Portimao Blue, Skyscraper Grey, and the spectacular Isle of Man Green of the G82 M4, or in exposed carbon fibre weave finish for carbon components. Every piece is engineered to OEM-grade fitment standards across all 4 Series models, generations, and body styles. Every order ships nationwide across South Africa with full tracking, and our team is available to assist with generation compatibility, body style specific fitment confirmation, LCI facelift fitment differences, M Sport versus standard bumper specifications, and installation referrals.
