Especially since the car appears to be 02-03 Civic Si. I bet the car is a smaller team, perhaps an amateur, that has little outside funding. Most professional teams now don't use factory wheels.
There was a rally ITR a while back( that was also for sale) that used some old ass infinity factory wheels because they were the cheapest plentiful wheel around. He has like 3 set of them lol
There was a rally ITR for sale near me not too long ago, car was supercharged and pretty much every suspension part was aftermarket or beefed up oem, all for 12k. Car came with a few sets of OZ Rally wheels, and a set of ITR wheels.
