STROM
B46
RACE PROGRAM
WHAT IS IT?
An engineered and developed race car that is manufactured in quantity to make it both cheaper to build and fully sorted and reliable from the moment it hits the track. Just like a factory race car from BMW, Porsche or Audi. The initial version is designed to be a GT4 level car capable of competing in the NASA ST2 and ST3, NASA GTS or WRL.
A complete support ecosystem for the car after it has left our facility that includes software and technical updates, a user manual, recommended setups, an inventory of replacement parts available at discounted pricing, engineering support and a parts trailer at select tracks to reduce logistics for car owners.
