Class Calculator

BIMMER CHALLENGE is based on a points accumulation system. The sum of your vehicle “Base” points and “Modifications” points will determine your Competition Class. The series is divided into five (5) different Competition Classes, each with a set range of points, to encourage all drivers of any skill to participate.

Use our automatic points calculator to determine your BIMMER CHALLENGE Competition Class. Reference the classification list below to identify your Competition Class.

CLASSIFICATION NOTES

  • BIMMER CHALLENGE reserves the right to re-classify any car it deems belongs in a different class, regardless of the total number of modification points i.e. a car that is fully stripped + aero + slicks and outputs twice the power as from the factory may be deemed a B1 car.
  • Cars will be selected at random during every event to ensure integrity of classing (weight, tires, mods list, etc). Failure to properly fill out spec sheet will result in loss of all accumulated points for the current season.
