About us

Carbon fibre and fiberglass aero parts, made in our own workshops

G.R.A.M.S Styling designs and makes carbon fibre and fiberglass aero parts for cars: GT wings, front splitters, rear diffusers, canards, side skirts, bumpers and full body kits. Every part is made in one of our two workshops, in the UK and in Lithuania. No middleman, no reseller: you buy from the maker.

We have been moulding and laminating car parts for more than 10 years. In that time our customers have left us over 99% positive feedback and earned us the Top Seller title on eBay. Many of those cars are in our customer cars gallery, and you can watch us in the workshop on YouTube.

Perfect Fit Guaranteed

Every mould is taken from a real car of that generation, so the part follows the real body lines instead of a drawing. The result is a part that lines up at the first fitting. If it does not fit, we sort it: that is our Perfect Fit Guaranteed promise, on every part we sell.

Our range covers diffusers, bumpers, side skirts, side steps, splitters and lips, canards, spats, wing mounts, side extensions, fender flares and more, for Japanese, European and American cars as well as universal parts that suit any build. Browse the parts by car brand to find yours.

Fiberglass parts: strong, light and ready to paint

Our fiberglass parts are hand laid and cured at high temperature, which gives a stronger and more rigid part than a cold cure. They come with a white or black gelcoat, ready to paint or to run as they are. Fiberglass is light, durable and bendable, which is why it is the choice of most street builds.

Carbon fibre parts: epoxy infused under vacuum

Our carbon fibre parts are made from premium carbon cloth and epoxy resin, infused under vacuum. Infusion puts the resin exactly where it is needed and nowhere else, so the part is as light and as stiff as carbon can be. A clear gelcoat protects the weave from fading in the sun, and our vacuum process leaves a dry carbon side on most parts. You can choose a gloss weave, a dry matte finish, forged carbon or coloured carbon on the product page.

The same mould is used for both materials, so you pick the lay-up that suits your build and your budget. Not sure which one? Our FAQ explains the difference, and you can always ask us before you order.

From our workshop to your door

Your order ships from the workshop closest to you: the UK workshop for the United Kingdom and the rest of the world, the EU workshop in Lithuania for Europe, so EU orders stay inside the EU with no customs surprises. Fiberglass parts are dispatched in 2 to 10 working days and carbon fibre parts in 5 to 15 working days. Unfitted parts in their original packaging come back within 30 days, and we provide part certificates for TÜV registration on request.

Quality and safety come first on every part we make. That is what over 10 years of feedback, and the cars you see on our social pages, are built on.
