BMW G80 G81 M3 & G82 G83 M4 Carbon Fibre Competition Front Splitter by FORM

Designed and developed using 3D CAD data by FORM in the UK & Germany, this is FORM's long awaited Competition Front Splitter for BMW G80 G81 M3 & G82 G83 M4. Forge Automotive can supply this splitter on its own, or fit it at our Darwen or Leeds site.

This is a 3-piece Splitter, with a subtle front extension and side winglets to create a blend of presence and solidity within the lines of the car.

The centre splitter has 2 parallel slats that line up with the vents above, this makes the piece OEM looking but unique in its design to other options on the market.

Installation is simple, it uses all OEM mounting points and can be fixed straight on.

No extra bolts are needed.

Crafted using a CFRP (wet carbon fibre) manufacturing method, this enabled cost to be kept down but ensured quality, design and longevity of the product could be kept at a high.

Common questions

What is wet-lay carbon fibre (CFRP)?
Wet-lay carbon is made by laying dry carbon cloth into the mould and applying resin by hand, then curing at room temperature or low heat, sometimes over a fibreglass or composite base. It gives the same 2x2 weave look as pre-preg for less money. The trade-off is more resin and a little more weight, and the finish depends more on the maker, which is why we only stock wet-lay parts from brands whose quality we have seen.

Is wet-lay carbon strong enough for a splitter or diffuser?
Yes for road use. The part is still carbon reinforced and stiff enough for a splitter, skirt or diffuser. If you want the lightest, most rigid option, choose the pre-preg version where the range has one.

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.

Is this pre-preg carbon?
No. This splitter is CFRP (wet-lay carbon fibre). FORM's pre-preg splitters are the T-CSL and Performance Pro.

Does it need drilling?
No. FORM state it fits to the OEM mounting points with pre-applied 3M tape and no extra bolts.
