Those are my super-heavy ultra-cheap 17x9 autocross wheels... 40lbs each!!!
Yeah, they suck, but they're the only low-cost 17x9 on the market. Anything else starts at 3x the price of these, or requires adapters.
Some day I'll have some forged lightweight wheels, but the ones I want are $800 each... so for now, these at $90ea will have to do.
My first autocross of the year is this Saturday! Can't wait!!!
