Just Listed
Where to start
Notes on the parts that decide a build, each shown against a current listing from that category.
Engine
The highest-stakes purchase in any build. Matching the platform, loom and ECU matters more than the headline power figure — a swap that fights the wiring costs more than the engine did.
Suspension
The part of a build most people underspend on. It is the difference between a car that just looks lowered and one that actually handles.
Turbocharger
Sizing a turbo wrong ruins an otherwise good build. Match the spool characteristics to how the car is actually driven, not to the peak number.
Brakes
More power always needs more stopping power to match it. Don't be the build with a 500hp motor and stock brakes.
