Lexan rally Sierra compatible with Avant Slot

Lexan Interior for Ford Sierra Rally: Less Weight, More Agility on Track

The Tectime M-L0077R is a lexan interior (lexan cockpit) specifically designed for the competition Ford Sierra, with direct compatibility with Avant Slot models. Made from high-strength lexan and vacuum formed (vacuum formed), this replacement part is one of the most effective upgrades you can apply to your car if you compete in classic or rally slot categories.

Function and Performance

The original injected plastic interior adds weight that, positioned high in the car, unnecessarily raises the centre of gravity. Replacing it with this lexan interior results in a significant weight reduction that translates into two immediate benefits:

• Reduced body roll: the car works flatter in corners, with less tendency to roll the body outward.
• Better response in quick direction changes: by reducing inertia at the top, the car reacts quicker and more predictably.

In setups where every tenth of a gram counts, lightening the upper part of the car is one of the most cost-effective resources before touching the mechanics or electronics.

Compatibility

This interior is moulded to fit precisely the dimensions of the Ford Sierra rally from Avant Slot, respecting the necessary space for the motor and the rest of the mechanics of that reference. If you are using an Avant Slot body on another base, check that the cockpit dimensions match before installing this replacement.

Assembly and Preparation

As it is a vacuum-formed lexan piece, it may require some fine adjustments with scissors or a cutter before final assembly. We recommend testing the fit dry before applying any adhesive. If you plan to paint it to add detail to the cockpit, paints from the Tamiya or Vallejo ranges adhere well to lexan as long as you apply a suitable primer for this material.

Common Mistakes

• Forcing the fit without prior adjustment: lexan is flexible but can permanently deform if pressed without checking the fit first.
• Using incompatible glues: adhesives based on aggressive solvents can attack lexan. Opt for low-viscosity cyanoacrylate or glues specifically for clear plastics.
• Painting without primer: on unprepared lexan, paint tends to chip off with use. A thin layer of flexible primer prevents this issue.

Frequently Asked Questions

Which specific Avant Slot models is this interior compatible with?

The M-L0077R is designed for the Ford Sierra rally from Avant Slot. If you have doubts about whether your specific Avant Slot reference matches the dimensions for which it is moulded, check the reference number of your body before placing the order.

Is it necessary to paint it, or can it be mounted directly?

It can be mounted directly as it comes. If you want to add visual detail to the cockpit, it can be painted with the appropriate products for lexan, always with prior priming.

How much weight is saved compared to the original interior?

The weight saving depends on the original interior of each Avant Slot reference, but in general, vacuum-formed lexan interiors are significantly lighter than injected plastic ones. We do not publish specific figures that are not verified by the manufacturer.

Can it be used in club races with strict regulations?

It depends on the regulations of each club or championship. Some allow the replacement of the interior as long as it does not modify the exterior silhouette of the body. Check your organisation's rules before competing.

Does this replacement include any decorative elements or is it just the cockpit structure?

The M-L0077R is the lexan cockpit structure, with the characteristic shapes of the Sierra rally interior. It does not include driver figures or additional elements.

The Tectime M-L0077R is a vacuum-formed lexan cockpit designed for the Ford Sierra rally, fully compatible with Avant Slot models. This lightweight interior replacement significantly reduces body roll and improves directional response on the track. A straightforward and effective upgrade for slot car enthusiasts competing in classic or rally categories.
