We engineered interactive mechanics for Coyote Kits.
A bespoke 2D visual steering-wheel configurator with instant mathematical state calculation matrices across infinite component variations — every option resolving synchronously, with no server round trip.

Automotive · Configurator Tooling — United States
The challenge
Coyote Kits sells configurable steering wheels with thousands of valid component permutations. The legacy tool round-tripped every change to the server, so each click stalled behind a spinner — killing the buying momentum a configurator is supposed to create.
The refactor
Mathematical state matrix
We modeled every option set as a pure matrix, so any combination resolves in a single synchronous pass — no network, no spinner, no perceptible latency.
Canvas render pipeline
The 2D preview repaints on a requestAnimationFrame loop at 60fps, decoupled from React state so the interface never blocks on a redraw.
Validation hooks
Custom hooks validate each permutation against compatibility rules in-memory, surfacing invalid combinations instantly instead of failing at submit.
Implementation
1// useConfigurator — synchronous, zero-latency permutation solver2export const useConfigurator=(base:Config)=>{3 const[state,setState]=useState<Config>(base);4 const valid=useMemo(()=>RULES.every(r=>r(state)),[state]);5 const apply=useCallback((k:Key,v:Val)=>setState(p=>solveMatrix({...p,[k]:v})),[]);6 return{state,valid,apply};};A pure in-memory permutation solver — every option change validates and resolves synchronously, so the preview never waits on the network.
The outcome
Configuration is now instant: zero perceptible latency across infinite valid permutations, with the 2D preview holding 60fps. The frictionless tool turned a stalling step into a conversion driver.
