Why GPE
Built by engineers who race
Real World Experience
We design, build and race our own cars. What we learn on track goes into yours.
In-house engineering, fabrication and machining
Design, analysis, fabrication and CNC machining under one roof, so custom parts don't wait on outside shops.
You talk directly to your builder
The person planning and building your car is the person you talk to, from the first call to handover.
Every car is road and track tested before handover
Problems get found here, not by you on the drive home.
