Holly’s build

Monsta S7 + customer projects
Build stories.
Not parts lists.
Go behind the build of our 904 HP Monsta S7, meet the customer projects joining the showcase and explore ideas for your own car.
The complete vehicle
Why the build matters more than the shopping list.
A successful project begins with the car, its condition and how the owner wants it to feel. Follow the Monsta S7’s specification and workshop process, then discover the customer vehicles joining our build stories.
Looking for ideas? Our separate build-route guides explain the systems, order of work and practical trade-offs to consider. They are planning guides, not individual customer case studies.

Meet the Monsta S7
From a stock 420 bhp executive coupe to a 904 hp, 1050 Nm rolling development platform—built to show what happens when every system is treated as part of one car.
Beyond the Monsta S7
Customer
projects.
Different cars. Different ambitions. The same attention to the complete build.
Meet the next vehicles joining our showcase. Their individual stories, specifications and workshop galleries are coming soon.

Vehicle.
Goal.
Constraints.
You do not need a finished parts list. A better first conversation covers what you drive, what is already fitted, what you want to change, how the car is used and what must not be compromised.
- 01
Understand the car
Health, history, software, installed parts and known concerns establish the real starting point.
- 02
Define the outcome
Power delivery, sound, appearance, control, comfort, budget and legal use shape the brief.
- 03
Connect the systems
Calibration, cooling, fuelling, drivetrain, brakes, tyres and fitment are planned in the right order.
- 04
Agree and document
The route, limitations and next stages are explained before the build grows.
