Custom Wide Body Kit for BMW 4 Series (G22/G23/G26) — Bespoke Aero by Hodoor

Why BMW 4 Series Owners Choose Custom Body Kits

The G22/G23/G26 4 Series brought BMW's most polarising design element — the vertical kidney grille — into the compact-GT segment. Love or loathe the grille, the car beneath it is a genuinely capable sporting platform with a low centre of gravity and well-sorted chassis. Owners who want to push the 4 Series' visual presence further, or close the gap to the M4 Competition without the powertrain premium, find Hodoor's custom body-kit programme an ideal solution. Every component is developed from 3D-scanned body data, produced in-house, and available for delivery to more than 40 countries.

Wide Body Kit Options for BMW 4 Series G22/G23/G26

Hodoor's wide-body programme for the 4 Series comes in two stages. Stage 1 adds 20 mm per side via smoothly blended arch extensions that maintain the car's factory lines while fitting wider rubber. Stage 2 is a full 40 mm-per-side conversion with bolt-on carbon arches, widened sill panels, and a revised rear bumper — delivering a stance that rivals the M4's footprint. Both stages are compatible with Coupé, Convertible, and Gran Coupé body styles, and are available in fibreglass, PU-RIM, or dry carbon fibre.

Carbon Fiber Components for BMW 4 Series G22/G23/G26

Carbon fibre details on the 4 Series create a motorsport-inspired aesthetic that complements the car's low-slung proportions. Hodoor's catalogue includes mirror caps, grille surrounds (or full grille replacements in carbon mesh), front splitter elements, side-sill trims, rear diffuser, and boot-lip or roof spoilers. All parts are autoclave-cured and sealed with UV-resistant clear coat. Gloss, satin, matte, and forged-carbon textures are offered as standard options.

Front Bumper and Lip Upgrades

Hodoor's front bumper for the 4 Series deepens the lower intake aperture and adds sculpted brake-cooling ducts in the outboard sections. The design integrates with factory sensors, cameras, and the adaptive LED headlamp system. A two-piece carbon splitter bolts beneath the bumper, adjustable in depth to suit lowered or standard suspension setups. For owners who want maximum front-axle grip, optional carbon canards bolt to the bumper corners and can be removed tool-free for daily driving.

Rear Diffuser and Spoiler Options

Hodoor's rear diffuser for the 4 Series replaces the factory lower valence and is available in quad-tip and dual-tip exhaust configurations. Vertical carbon fins improve rear stability and add visual depth. Spoiler options include a boot-lip extension in carbon for a clean, understated look, a PSM-style ducktail for moderate aggression, and a raised GT wing on aluminium uprights for track-focused builds. Gran Coupé owners can choose a roof spoiler that extends the fastback roofline. All pieces are autoclave-grade dry carbon.

Side Skirts and Fender Flares

The 4 Series' compact wheelbase demands precise side-skirt proportions. Hodoor offers a flat-profile skirt for a clean, factory-plus appearance and a deeper blade-style version with aero fins for builds that prioritise airflow management. Both run from the front arch to the rear, attaching at factory mounting points. Matching fender flares integrate with the wide-body arches, maintaining OEM-level panel gaps. Available in fibreglass or carbon, in primer or finished form.

Custom Forged Wheels for BMW 4 Series G22/G23/G26

Forged wheels reduce unsprung mass and sharpen the 4 Series' already eager turn-in. Hodoor offers monoblock and multi-piece designs in 19- to 21-inch diameters, each cleared for factory M Sport brakes and popular aftermarket big-brake kits. Finishes include satin bronze, gloss black, brushed aluminium, polished lip with painted centre, and fully custom colours. Every set ships hub-centric and dynamically balanced.

Installation and Fitment Guide

Each 4 Series kit ships with body-style-specific hardware, alignment templates, and an illustrated installation manual. Bolt-on parts like splitters, mirror caps, and spoilers install in a few hours. A full wide-body conversion with paint typically requires three to five days at a professional body shop. Hodoor provides live video support during installation and works with approved fitment centres in Europe, North America, the Middle East, and Asia-Pacific.

Frequently Asked Questions

Do the kits fit all 4 Series body styles?
Front bumper, splitter, mirror caps, and grille components are shared across G22 Coupé, G23 Convertible, and G26 Gran Coupé. Side skirts, rear diffusers, and spoilers are produced in body-style-specific versions.

Can I achieve an M4-style look on my 430i or M440i?
Yes. Hodoor's Stage 2 wide-body programme delivers a footprint comparable to the M4 Competition, including widened arches and an aggressive diffuser, without requiring the M4's mechanical underpinnings.

Are parking sensors and cameras retained?
All Hodoor bumpers are pre-drilled for factory sensor and camera positions. No system recalibration is typically required after installation.

What is the delivery timeline?
Production takes six to eight weeks. Insured worldwide shipping adds five to fifteen business days, depending on destination and customs processing.
