BMW M2 G87 TR87 Pre-Preg Carbon Fibre Winged Side Skirts by TREVORA (2023 on)

The TREVORA TR87 Carbon Side Skirts are an exclusive, first-of-their-kind aerodynamic upgrade designed specifically for the BMW G87 M2 (2023+). Part of the TREVORA TR87 body kit - the most comprehensive aftermarket carbon programme available for the G87 - these side skirts are crafted from premium 2x2 twill pre-preg carbon fibre, the same material specification used in professional motorsport. Forge Automotive supplies these side skirts and can fit them at our Darwen and Leeds sites.

Precision fitment is achieved through TREVORA's use of advanced CAD design methods, which ensures the skirts integrate with the G87's specific sill geometry without gaps or misalignment. The aerodynamic profile improves the car's efficiency by managing airflow along the sill and reducing turbulence, contributing to improved stability and a more purposeful stance.

Installation uses a dual-fixing method: 3M VHB tape is pre-applied to the contact surface and 14 self-tapping screws provide structural fixing at the mounting points.

Supplied, fitted and finished by Forge Automotive

Forge Automotive can fit these side skirts at either of our sites: Darwen in the North West or Gildersome, Leeds in Yorkshire. Forge Automotive can also finish these side skirts before fitting: paint protection film (PPF) to guard the carbon, a colour change or satin wrap, or colour matching to the car. Ask when ordering.

Common questions

What is pre-preg carbon fibre?
Pre-preg is carbon cloth that arrives from the mill already impregnated with a measured amount of resin. The part is laid up in the mould and cured under heat and pressure, usually in an autoclave or oven. Because the resin content is controlled, the finished part is lighter, stiffer and more consistent than a hand-laid one, with a cleaner weave and better dimensional accuracy. It costs more to make, which is why pre-preg parts sit at the top of a range.

What does "dry carbon" mean?
Dry carbon is the everyday name for a pre-preg part: carbon fibre all the way through, rather than a carbon skin over a fibreglass or plastic base. The surface still has a clear lacquer, but there is no excess resin in the laminate, so the part is light and rigid.

What is a 2x2 twill weave?
The weave pattern in the carbon cloth. In a 2x2 twill each strand passes over two and under two, which gives the diagonal pattern BMW use on their own M Performance and M carbon parts. Choosing 2x2 means aftermarket and factory carbon on the same car match.

How do I look after a carbon fibre part?
Treat the lacquer like paint: wash with pH-neutral shampoo, avoid harsh solvents, and wax or seal it. UV is what ages carbon, so a protected finish lasts longer. Forge Automotive can apply paint protection film to any carbon part before fitting, which guards against stone chips and keeps the weave clear.

How are the skirts attached?
The TR87 side skirts use 3M VHB tape (pre-applied) for immediate adhesion plus 14 self-tapping screws for long-term structural security. Both are included in the kit.

Will these fit only the G87 M2?
Yes. These skirts are designed exclusively for the BMW G87 M2 (2023+). The sill geometry is specific to that model.

Is it TUV approved?
TREVORA say TUV approval for the TR87 range is pending and not yet guaranteed. Ask before ordering if you need it for your region.
