Could Infinity Flyers replace current Millennium Flyers? in Kings Island Posted 7 hours ago I think The Racer is fine the way it. I have never had a problem with the roughness of the ride. Not ever coaster needs to be Uber smooth. A general clean up and paint job would do the entire park wonders. Hopefully with the loss of 2020 season or most of one we can start to see improvements like this.
