What Are Split Rim Wheels and Should You Refurbish Them?
Split rim wheels — also known as multi-piece or 3-piece alloys — are iconic in the world of performance cars, classic builds, and high-end custom projects. But what actually makes them different, and when should you consider refurbishing a set?
Whether you’ve just picked up a tired set of BBS RS wheels or you’re curious about how split rims work, this blog breaks down the essentials.
🔍 What Is a Split Rim?
A split rim is a type of alloy wheel constructed from two or three separate components:
- Outer lip – the face of the wheel
- Inner barrel – the rear section
- Centre – the piece that bolts to the hub
These parts are bolted or riveted together using specialised hardware. Depending on the design, they may also be sealed with RTV silicone or a rubber gasket to keep the tyre airtight (for tubeless setups).
This modular design makes them highly customisable — from changing finishes to adjusting widths — but also more complex to maintain and refurbish.
✅ Why Are Split Rims So Popular?
Split rims aren’t just about looks (though they do look incredible). Their popularity comes down to several practical and performance-based benefits:
- Customisation: Mix and match lip depths, barrel widths, and centre finishes.
- Repairability: Damage a lip? Replace just that section.
- Motorsport Proven: Used in racing for their balance and strength-to-weight ratio.
- Show-Ready Aesthetics: Split bolts and polished lips are a timeless styling cue.
🧼 When Should You Refurbish Split Rims?
Unlike standard one-piece alloys, split rims must be treated with care during refurbishment. If your wheels show signs of corrosion, leaking air, or have curb rash or faded paint, it’s time to refurbish.
Warning signs include:
- Visible damage on lips or barrels
- Leaking between wheel sections
- Rusted bolts or missing rivets
- Dull or peeling lacquer
- Uneven tyre wear or balancing issues
🔧 What’s Involved in Refurbishing Split Rims?
Refurbishing split rims is a precision process — not something for DIY shortcuts. Here’s a general overview of what it includes:
- Disassembly – Each wheel is unbolted and separated into its parts.
- Inspection – Checking for cracks, corrosion, or bent lips.
- Surface Prep – Media blasting or stripping old finishes.
- Refinishing – Powder coating, polishing, or painting.
- Reassembly – Bolts torqued to spec, with new sealant applied.
- Testing – Pressure tested to ensure airtight seal.
🔩 Are All “Split Rims” Genuine?
Not necessarily. Some one-piece wheels mimic the look of split rims by adding cosmetic bolts. These are often referred to as “fake split rims” and can’t be disassembled. If you’re unsure, speak to a wheel specialist before attempting refurbishment.
💬 Real-World Tip from the Workshop
“We always torque split rim bolts to manufacturer specs — usually around 22–26 ft-lbs — and reseal using RTV silicone. Skipping these steps or powder coating wheels while they’re assembled is a disaster waiting to happen.”
If your refurbishment shop can’t explain their process or avoids full disassembly, it’s time to look elsewhere.
💷 How Much Does It Cost to Refurbish Split Rims?
Prices can vary depending on wheel size, damage, and finish, but here’s a rough guide:
| Size | Full Refurb (Per Wheel) | Polishing Only |
|---|---|---|
| 17" | from £145 | from £60 |
| 18" | from £160 | from £70 |
| 19" | from £170 | from £75 |

🛡 Is Refurbishment Worth It?
If you own a set of genuine split rims, refurbishment is almost always worth the investment. Replacing a damaged wheel outright can be costly — especially if it's rare or discontinued. A professional refurb not only saves money, it also revives your wheels’ strength, style, and performance.
