Aluminum flywheel
about 10lbs

This came off a 1999.5 audi a4 1.8t quattro. It came with the car when I got it. The guy had it installed but didn't like how it drove since he was often stuck in traffic so he had it removed. It would need to be resurfaced or have a new plate put on as it is a bit scuffed up from trying to drive it in traffic.

I'll take $250 obo
I'd also be willing to do a trade for a heavier flywheel maybe like 17-20lbs
