You have decided to take the BMW to the track and you don't want to use its original wheels and tires.
The Kosei K1 Racing is a proven wheel that is used by autocrossers and track guys every weekend. They are lightweight in a 17x8.5 wheel and 16.8 lbs. currently priced at $175.00 per wheel. Easy-to-clean and keep looking good, the 6-spoke design and open look will also help keep your brakes cool.
Pictured here are Grand Am Continental Challenge cars in the ST Class with Kosei K1 Racing wheels installed.
