Carbon steering bar (Ackerman) Mini 8IGHT

Precision in the steering of your Mini 8IGHT thanks to carbon

The steering link (Ackerman) LOSB1871 is the original Losi spare part specifically designed for the Mini 8IGHT. Made from carbon, this component plays a critical role in the vehicle's steering geometry: the Ackerman principle ensures that the inner and outer wheels describe correct turning arcs in every corner, reducing tyre wear and improving steering response.

Function and performance

The Ackerman geometry is one of the most influential factors in a buggy's cornering behaviour. A worn steering link —deformed, cracked, or with play— directly translates to imprecise corner entry, uneven tyre wear, and loss of driver confidence.

Being made from carbon, this link offers superior stiffness compared to conventional plastic versions, better absorbing lateral impacts without deforming. The low weight of carbon also helps maintain unsprung mass at optimal levels, which is particularly relevant in a competitive buggy like the Mini 8IGHT.

Compatibility

• Specifically designed for the Losi Mini 8IGHT.
• Original Losi reference: LOSB1871.
• Check your model's manual to confirm compatibility with versions or evolutions of the kit before assembly.

Assembly and preparation

Replacing the steering link is a relatively straightforward operation, although it requires attention to maintain toe adjustment and steering centring after installation. It is advisable to take the opportunity to check the condition of the steering rods and adjacent ball joints, as they work in conjunction with this part. An incorrect adjustment of the Ackerman geometry can introduce understeer or oversteer that is difficult to correct solely with electronics.

Common mistakes

• Not readjusting the steering after installation: replacing the link without checking centring and toe can lead to erratic behaviour on track.
• Over-tightening the fixing screws: carbon tolerates compression well, but excessive tightening can create micro-cracks at the anchoring points.
• Ignoring the wear of adjacent ball joints: a new link combined with worn ball joints will not fully restore steering precision.

Frequently asked questions

Why is the Ackerman principle important in an RC buggy?

The Ackerman geometry ensures that, in a corner, the inner wheel turns at a greater angle than the outer wheel. This prevents the tyres from fighting each other while tracing the arc, improving traction and reducing wear. In competition, correct Ackerman geometry directly influences lap time consistency.

Is carbon more fragile than plastic against strong impacts?

Carbon is stiffer and lighter, but it can be more susceptible to fractures under very severe impacts at specific angles. Under normal usage and competition conditions with the Mini 8IGHT, it offers superior durability compared to standard plastic parts due to its greater resistance to deformation.

Do I need special tools for assembly?

No. Assembly is done with the usual tools from the Losi kit (Allen keys of the appropriate sizes). The key is to have a gauge or toe ruler to correctly readjust the steering geometry after installation.

How often should I check this part?

It is recommended to inspect the steering link after each session where the vehicle has suffered significant lateral impacts. In competitive use, a systematic check before each race is the best guarantee to avoid surprises on track.

The Losi LOSB1871 carbon Ackerman steering plate is an original replacement part for the Mini 8IGHT buggy. Made from carbon fibre, it delivers superior stiffness and reduced weight compared to standard plastic versions, ensuring precise Ackerman geometry and consistent steering response. A must-have spare for competitive RC buggy drivers looking to maintain peak handling performance.
