Rennen Plus

An Australian performance-parts business with five partner brands, thousands of parts and no way for a customer to find what fits their car, priced in Australian dollars, on a phone.

  1. One front door

    Five partner brands, each with its own site, and no shared way in. The home page is a search bar over a film by Zach Sullivan, with the five marks underneath.

  2. The car comes first

    Owners could not tell what fits their car. Every part is reached by picking the car, 228 of them across 21 makes, and a part never shows on a car it does not fit.

  3. One page per car

    The range lived in five brands' sites and supplier PDFs. Search a chassis code like 992.2 and one page holds the package, every part and the questions owners ask.

  4. A price you can act on

    Quotes were a spreadsheet and a phone call, worked up from US retail. Each part now shows a landed Australian price with GST and import, and it moves when an option changes. Pick a finish and the gallery leads with a live 3D material of it.

  5. One way around

    Five brands, 228 cars, an events calendar and a dealer map needed a single way in. One side menu runs on every device, and its event slot comes and goes from the data.

  6. Answers before the call

    Fitment questions used to wait for a phone call. An assistant grounded in the catalogue finds the car, links the page and the part, and hands over to a consult when it should.

  7. Someone to fit it

    Owners had nobody local to fit the parts. Forty-five dealers and installers now sit on a map, searchable by postcode.

  8. One way to enquire

    Every sale ends in a call, because fitment is checked by a person before anything ships. Every button opens the same panel, with the car and the part already filled in.

  9. Proof on real cars

    There was nothing showing the parts on a customer's car. Nine builds each link back to the parts on them, eight with the owner's own words.

  10. Built for a phone

    Most visitors arrive on a phone from Meta ads. The phone site is its own system: two fonts, six text sizes and every control at least 44px tall.
