Case study · Gapped Performance

One grille. Then a whole store.

Gapped Performance makes carbon-fibre parts by hand in South Africa. It started with one product, a carbon front grille for the Mazdaspeed 6 and Mazda 6 MPS, and one landing page to sell it. AussyPrompt ONE planned the page, then the store it grew into.

The brief

What the project had to do

A handmade part needs a page that shows the craft and makes ordering simple: the fit, the material, the lead time and a safe way to pay. As the range grew, the same site had to sell parts from many suppliers and help drivers find what fits their car.

  • Show why handmade carbon is worth the wait
  • Make the fit and the six-week lead time clear before anyone pays
  • Take card payments safely
  • Grow from one product to many, from many suppliers
  • Answer buyers' questions at any hour, without making things up

What AussyPrompt ONE did

A landing page first, then the store

Austin described the grille and the business behind it to AussyPrompt ONE. ONE planned the landing page section by section, then planned the store when the range grew. Claude Code built both from ONE's build packs.

The landing page plan

Every section in order: the reveal, OEM fit, the material, the film, the six-week build, fitment and the order form, with one clear action throughout.

The store plan

Products, suppliers, cars and fitment, customers, orders and reviews, and how each one links.

Every screen

Shop by car, the parts catalogue, product pages, cart and checkout, customer accounts and an admin area.

Automations

A supplier importer that brings in catalogues from 18 suppliers, and order confirmations once a payment goes through.

Taylor, the shop assistant

An AI assistant built on Claude. It answers only from facts the server gives it about the shop, and it has a monthly spending limit.

Checks

A 25-check test script that runs before each release.

The result

See it live

OEM fit, explained

What fits, how it mounts and what's in the box, before the buyer has to ask.

OEM fit, explained

Show the material

Dry carbon under 200 grams, with the weave up close.

Show the material

Be honest about the wait

Six weeks from mould to finished part, shown step by step, so the lead time sells the craft instead of putting buyers off.

Ordering on the same page

Pick the carbon, the fitment and the quantity, then pay by card through Peach Payments.

Ordering on the same page

Then: shop by car

As the range grew, drivers pick their car and see the parts that fit it.

Then: shop by car

A page for every part

Photos, options, stock and delivery time, with add to cart.

Taylor answers questions

The shop assistant helps buyers find the right part and answers from the store's own facts.

How it was built

Claude Code built the landing page first, then grew it into the store, in plain PHP with no build step, on Hostinger.

  • Plain PHP: quick to load and simple to host
  • Peach Payments hosted checkout, so card details never touch the site
  • Customer accounts and product reviews
  • A supplier importer for 18 catalogues
  • Taylor, built on Claude with the Anthropic PHP SDK, with a monthly spending limit

What they have now

  • A live store at gappedperformance.com
  • The Mazdaspeed 6 and Mazda 6 MPS carbon grille, still the hero product
  • Shop by car across the whole range
  • Card payments, accounts, reviews and an AI shop assistant
