Builds
Car + ORIGINAL perk + one INSTALLED perk + SHIFT setup.

ORIGINAL · APEX GRIPINSTALLED · TORQUE
Example: Race Car with TORQUE
Start with a job
Pick something concrete: tidy exits, sustained LOCK, a longer BOOST burst or a clean high-speed lap. Choose the car and practise a baseline first.
Add one perk
After PERKULATOR unlocks, install one available perk beside the car’s ORIGINAL perk. You cannot install its own perk again. LEGENDARY perks stay with their original cars.
Give SHIFT a purpose
Make the second setup useful for a different part of the track. Switch before the corner or exit that needs it. Ordinary setups keep the same total attribute budget.
Compare fairly
Try the same track, line and objective for several laps. A build that helps DRIFT scoring may make your fastest lap harder. The ideas here are experiments, not rankings.
