RC10B7 vs RC10B7.1 – Is It Worth Converting Your B7?

When Team Associated released the RC10B7.1, one question quickly started appearing in clubs and online forums:

"Should I convert my RC10B7, or am I better off buying the new kit?"

On paper, converting an existing B7 seems like the cheaper option. After all, the B7.1 is an evolution of the original platform rather than a completely new design.

To find out whether that's really the case, we've priced every part required to convert an RC10B7 into B7.1 specification.

In this guide you'll find:

• The key differences between the RC10B7 and RC10B7.1
• The complete conversion parts list
• The total cost of converting your buggy
• Whether buying the individual parts actually makes financial sense

What's Changed on the RC10B7.1?

The RC10B7.1 isn't a completely new buggy.

Instead, Team Associated refined the already successful B7 platform with a number of updated components and additional tuning options.

The changes include revised:

• Front suspension components
• Steering geometry
• Shock tower options
• Rod ends and ball studs
• Anti-roll bar hardware
• Chassis tuning components

Many of these updates are aimed at improving consistency and providing racers with more setup options on today's high-grip tracks.

Because the basic platform remains the same, many of these updated parts can be fitted to an original RC10B7.

RC10B7 to RC10B7.1 Conversion Parts List

Below is the complete list of parts required to convert a Team Associated RC10B7 into RC10B7.1 specification.

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

This is where things become interesting.

The total cost of purchasing all 17 conversion parts is:

£306.51

A brand-new Team Associated RC10B7.1D Team Kit currently costs around:

£389.99

That's a difference of just £83.48.

For that extra £83.48, the complete kit includes approximately 135 additional parts that aren't included in the conversion list.

These include:

• Complete transmission components
• Bearings
• Hardware
• Gearbox components
• Driveshaft parts
• Plastics
• Shock parts
• Body and wing
• Wheels
• And all the other replacement parts supplied in the full Team Kit.

Our Recommendation

If you're planning to buy every part needed to convert a standard RC10B7 into a B7.1, we don't think it's the best value.

For only around 21% more money, the complete B7.1D kit gives you:

• A completely fresh car
• Around 135 additional spare parts
• New bearings throughout
• New hardware
• New drivetrain components
• A box full of replacement parts you'll almost certainly use over time

In our opinion, the complete kit represents much better value than purchasing every conversion part individually.

However, there are still situations where buying individual B7.1 parts makes perfect sense.

When Should You Buy the Parts Instead?

Buying individual conversion parts can still be worthwhile if:

• You've broken a component and need to replace it anyway.
• Your B7 already has some of the newer parts fitted.
• You're gradually upgrading your buggy over time.
• You only want specific B7.1 improvements rather than a complete conversion.

Many racers upgrade their cars this way, replacing worn parts with the latest versions as maintenance is carried out.

At Seth's RC we stock genuine Team Associated race spares for both the RC10B7 and RC10B7.1.

Whether you're replacing a suspension arm after a crash, rebuilding a differential or upgrading to the latest specification one part at a time, we aim to stock the genuine race parts you actually need.

Final Thoughts

The RC10B7.1 is an excellent evolution of the already successful B7 platform.

While it's technically possible to convert a B7 by purchasing all 17 updated components, the numbers tell an interesting story.

A full conversion costs £306.51, while a brand-new RC10B7.1D Team Kit costs £389.99 and includes approximately 135 additional parts.

If you're starting with a standard B7 and want every B7.1 upgrade, we'd recommend putting the money towards the complete kit instead.

If, on the other hand, you're simply replacing worn or damaged parts as you go, upgrading to B7.1 components individually remains an excellent way to keep your buggy competitive without rebuilding it from scratch.

That's the approach we'd recommend—and it's exactly why we stock the individual Team Associated race spares that racers actually need.
