The BMW 3 Series F30 and F31 is one of the most modified cars on UK roads — and for good reason. The generation that ran from 2013 to 2019 hit a sweet spot between affordability and platform quality that makes it the perfect base for an OEM+ exterior build. A clean set of gloss black styling parts on an F30 or F31 reads as a £40,000 M Sport spec, not an aftermarket add-on.
KITS UK stocks a complete range of body kit parts for both body styles — the F30 Saloon and the F31 Touring — from individual parts at £15 up to full packages at £553. This guide lists every option with verified pricing, real product images, and a clear build order for the most common budgets.

F30 Saloon vs F31 Touring — What's Different
The F30 and F31 share the same front end, the same side sill geometry and the same kidney grille housing — so the majority of KITS UK styling parts fit both body styles from a single product listing. The differences only appear at the rear:
| Part | F30 Saloon | F31 Touring |
|---|---|---|
| Front Splitter | ✅ Same part | ✅ Same part |
| Side Extensions | ✅ Same part | ✅ Same part |
| Rear Diffuser | ✅ Same part | ✅ Same part |
| Kidney Grilles | ✅ Same part | ✅ Same part |
| Mirror Caps | ✅ Same part | ✅ Same part |
| Badges | ✅ Same part | ✅ Same part |
| Boot Spoiler (MP Style) | ✅ F30 specific | — Touring has OEM spoiler option |
| Boot Spoiler (V Style) | ✅ F30 Saloon only | — Not compatible |
| F31 OEM Touring Spoiler | — Not applicable | ✅ F31 Touring specific (£561) |
| Full Performance Package | F30 version: £356 | F31 version: £297 |
| Ultimate Package | F30: £553 | F31: £494 |
Key rule: if you're ordering a full package, confirm whether you need the F30 or F31 version at checkout — the products are separately listed. For individual parts (splitter, diffuser, side extensions, grilles, badges), a single listing covers both body styles.

Shop F31 Ultimate →The F31 Touring is one of our most rewarding builds. The long roofline and estate proportions mean the side extensions do more visual work than they do on the saloon — they visually lower a car that would otherwise read as slightly tall. The combination of splitter, side extensions and diffuser on an F31 always draws attention from behind, which is where the Touring's best angle is anyway.
One thing to note: the F31 package is priced lower than the F30 equivalent (£297 vs £356 for the performance packages) despite covering the same three core parts. The Touring's rear configuration means the diffuser sits slightly differently — if you have any questions about fitment on a specific F31 variant, the team will confirm before dispatch.
Recommended Upgrade Order — F30 & F31
| Step | Upgrade | Cost | Why This Order |
|---|---|---|---|
| 1 | Front Splitter | £99 | The single highest-impact change on this platform — transforms the front end immediately. Start here before anything else. |
| 2 | M Style Grilles (gloss or matte) | £59 | The grilles are the most visible feature at eye level from the front. Replacing the chrome bars with black creates the M Sport look factory prices as a £2,000+ option. |
| 3 | Gloss Black Side Wing Badges | £15 | Small cost, immediate de-chrome at the most-noticed panel on the car. Pair with the grilles for a complete front-end transformation. |
| 4 | Rear Diffuser | £99 | Completes the rear of the car. Pairs with the splitter for a balanced, cohesive look front-to-rear. |
| 5 | Side Extensions | £99 | Connects front and rear styling. The car reads as a kit at this point, not individual parts. |
| 6 | Boot Spoiler (F30) or Tailgate Badge (F31) | £59–£69 / £15 | The finishing touch. On the Saloon, the spoiler completes the roofline. On the Touring, a gloss black tailgate badge completes the de-chrome. |
| Or | Full Performance Package (F30 or F31) | £297–£356 | If budget allows, skip steps 1–6 and order the package — same parts, better value, single delivery. |
The three core parts (splitter, diffuser, side extensions) bought individually on the current sale pricing cost £297 — exactly the same as the F31 Full Performance Package, and £59 less than the F30 package at £356. The packages include a spoiler and are better value as a combined order, but if you're building in stages and already have a spoiler, the individual parts at current pricing are strong value.
