F-1 racers experience 1.5 g's accelerating which is (by the looks of it) at least 3 times the g's this thing can make you feel... And that's the least acceleration in an F-1 car because it can generate 4 to 5 g's braking and 5.5 g's turning. There is no way a gravity based system can come close to that.
The best that chair could simulate is maybe a stock miata racing class.
which is why I was never good at GT or Forza. For one, I don't drive with my thumbs, and two; I get zero feedback from the "vehicle". granted nothing will be the same or as good as actually driving, but a good simulator will allow the drive to have all required type(s) of feedback to allow them to manage their responses properly and drive the vehicle as fast as it possible.
For SoCal TCLers, you can get a similar experience at Seat Time. They use iRacing as their sim package, and have a cockpit setup with articulation. I've talked to some people who have gone there, and they say it's incredible. Unfortunately, it's NOT cheap.
They cater to semi-pro or pro racers who want to learn a track for the first time, hence the pricing.
That is Beyond amazing.
