RC10B7 vs RC10B7.1 - How to Convert a B7 to a B7.1 (Parts List)

When Team Associated released the RC10B7.1, many racers who already owned the RC10B7 asked the same question:

Do I need a whole new car, or can I convert my B7 into a B7.1?

The good news is that the RC10B7 platform was designed with updates in mind. In most cases, you don’t need to buy a completely new kit. Instead, you can upgrade key components to bring your B7 much closer to the latest RC10B7.1 specification.

In this guide we’ll cover:

  • The main differences between the RC10B7 and RC10B7.1

  • Whether upgrading is worth it

  • The parts needed to convert a B7 to B7.1

If you’re rebuilding your car after a crash, refreshing worn parts, or preparing for BRCA regional racing, upgrading your B7 can be a smart move.

What Changed Between the RC10B7 and RC10B7.1?

The RC10B7.1 is an evolution of the original B7 platform rather than a completely new car. Team Associated refined the car based on feedback from top-level racers and real-world race results.

The biggest changes focus on durability, suspension geometry, and tuning options.

Key updates include improvements to:

  • Suspension arms and geometry

  • Chassis flex characteristics

  • Steering response

  • Weight balance

  • Updated plastics and revised components

These changes help make the B7.1 more consistent on modern high-grip carpet and astro tracks, which is where many UK clubs race today.

Because the overall platform is the same, many B7 owners can upgrade individual components rather than replacing the entire car.

Is It Worth Upgrading a B7 to a B7.1?

For many racers, the answer is yes — especially if your car already needs maintenance or replacement parts.

Typical situations where upgrading makes sense include:

  • Replacing worn suspension arms

  • Rebuilding the car for a new season

  • Preparing for regional or national racing

  • Improving durability after frequent breakages

If your car is already stripped down for maintenance, upgrading key parts can be a cost-effective way to modernise the platform.

Many racers also replace:
