The BMW 4 Series F32, F33 and F36 are among the most popular platforms for exterior styling upgrades in the UK. The coupé proportions of the F32, the open-top character of the F33, and the practicality of the F36 Gran Coupé all share the same platform — and critically, the same body kit parts.
This guide covers every KITS UK product available for the F32, F33 and F36, with verified current pricing, a breakdown of which parts deliver the best visual return, and a straight answer on what the full transformation actually costs. Whether you own a 420i, 428i, 430d, 435d or any other variant — the parts are the same and the prices below apply.
F32 vs F33 vs F36 — Which Body Style Do You Have?
| Code | Body Style | Years | Notes |
|---|---|---|---|
| F32 | Coupé (2 door) | 2013–2020 | Most common — 2 door, fixed roof |
| F33 | Convertible (2 door) | 2013–2020 | Soft-top — same front/side kit as F32, different rear spoiler vs F32 & F36 |
| F36 | Gran Coupé (4 door) | 2013–2020 | 4 door — different rear spoiler vs F32 |
The front splitter, rear diffuser, side extensions and grilles are the same across F32, F33 and F36. The spoiler is body-style specific — the F32 uses a boot lid spoiler, the F36 uses shallower spoiler. If you drive an F33 Convertible, check compatibility for the spoiler before ordering as this is also a different spoiler.
Always confirm your bumper specification (M Sport or SE) before ordering. KITS UK parts are primarily designed for M Sport bumpers.

Individual Parts Breakdown
If you're building the kit incrementally, here's what each part delivers and why it matters for the F32, F33 and F36 specifically.
Front Splitter
£99 was £139
The highest visual-impact single purchase available. Extends the lower bumper in gloss black, cutting the front end visually lower. Works on all F32, F33 and F36 variants 2013–2020.
Rear Diffuser
£99 was £139
Transforms the flat lower rear bumper with structured fins and vents. Combined with the splitter, the car reads as deliberately upgraded from both ends. F32, F33 and F36 compatible.
Side Extensions
£99 was £139
Completes the perimeter. Runs along the lower sill between the wheels, visually lowering the side profile. Most impactful when combined with front splitter and rear diffuser.
M Style Grilles
£49 was £69
Replace factory chrome-accented kidney grilles with uniform gloss black. The de-chrome effect on the front end is immediately visible and makes the car look significantly more considered.
F32 Boot Spoiler
£69 was £95
MP-style boot lid spoiler for the F32 Coupé. A finishing detail that references M Performance aesthetics. F32 Coupé specific — not for F33 or F36.
F36 Boot Spoiler
£59 was £79
Roofline lip spoiler for the F36 Gran Coupé. Particularly effective on the F36 because the longer C-pillar transition makes the spoiler visible at any angle. F36 specific.
Full Package Comparison
| Package | Price | Saving | Includes | Best For |
|---|---|---|---|---|
| Front End Package | £217 | £40 | Splitter + grilles + mirror caps | Front-only transformation |
| F32 Full Performance | £356 | £120 | Splitter + diffuser + side extensions | Complete 3-sided transformation |
| F33 Full Performance | £356 | £120 | Splitter + diffuser + side extensions | F33 Convertible — same kit as F32 |
| F36 Full Performance | £356 | £120 | Splitter + diffuser + side extensions | F36 Gran Coupé |
| F32 Ultimate Package | £756 | £310 | Splitter + diffuser + sides + spoiler + mirror caps + grilles + decals | Complete exterior overhaul in one order |
| F36 Ultimate Package | £756 | £310 | Splitter + diffuser + sides + roof spoiler + mirror caps + grilles + decals | F36 Gran Coupé complete build |
If you plan to eventually buy all three sides of the kit, the Full Performance Package at £356 is the right purchase — not because the three individual parts would cost more separately at current sale prices, but because the package delivers finish consistency across all three parts from the same production run. There is no risk of a mismatched gloss level between the splitter and diffuser when they are ordered as a set.
Gloss Black vs Carbon — Which Finish?
| Finish | Look | Best For | Verdict |
|---|---|---|---|
| Gloss black | OEM+ — works on any colour | Daily driver, any exterior colour | Most popular — recommended for most owners |
| Matte black | Flat, aggressive finish | Black or dark-coloured cars | Shows marks more — higher maintenance |
| Carbon look | Textured carbon weave appearance | Motorsport-inspired builds | Valid choice — buy all parts from same order |
| Carbon fibre | Real dry carbon, lightweight | High-specification builds | Higher price — contact KITS UK for availability |
For most F32/F33/F36 owners on UK roads, gloss black is the correct choice. It sits within BMW's own M Performance design language, ages well with correct maintenance, and delivers a consistent finish across every component when ordered as a set. The finish is injected and clear-coated which gives it resilience against minor chips and weathering.

Watch the F36 Installation
This KITS UK video shows a real BMW F36 Gran Coupé transformation — the same parts available in the collection above, filmed at the West Yorkshire workshop. The F36 kit in the video uses identical front splitter, rear diffuser and side extensions to the F32 and F33 — only the roof spoiler differs.
The video referenced above has over 1,900 views since publication — one of the strongest-performing installation videos on the KITS UK channel. The result shown is the same finish and fit available to order directly from KITS UK.
Common Buying Mistakes
- Confusing F32, F33 and F36 spoiler fitment. The boot spoiler is F32 Coupé-specific and F33 Convertible-specific. The Gran Coupé boot spoiler is F36-specific. They are not interchangeable. Check which body style you drive before ordering any spoiler.
- Not confirming bumper specification. M Sport and SE bumpers have different lower front bumper profiles. If your 4 Series is on SE specification, confirm compatibility with KITS UK before ordering.
- Buying individual parts when a package is more efficient. The Full Performance Package at £356 delivers all three sides in one consistent order from the same production run. If you plan to eventually fit all three parts, the package is the correct purchase.
- Mixing parts from different suppliers. Gloss black is not a universal standard. Two parts from different manufacturers will almost certainly show a finish difference under direct sunlight. Buying everything from KITS UK eliminates this risk.
- Rushing the splitter installation. The most common issue on F32/F33/F36 cars brought in after DIY attempts is front splitter misalignment — a 2–3mm gap on one side that is invisible from directly in front and immediately obvious from any other angle. Seat centre clips first and work outwards.
The F32, F33 and F36 are three of the most rewarding platforms to work on in the KITS UK workshop. The factory coupé, convertible and Gran Coupé lines already have sporting, low-slung proportions — the body kit additions reinforce what is already there rather than fighting the design.
If your budget allows for the Full Performance Package (£356) and the M Style grilles (£49), buy them together. The grilles are not included in the standard Full Performance Package but they complete the front end — the package transforms the perimeter of the car while the grilles de-chrome the face of it. Together for £405 you have the complete exterior transformation.
Add the spoiler at £59 to the full package and you have the most complete visual build available for the platform at £415 total.
