Disclaimer: I haven't driven a real manual since I sold my 93 grand am around 2000. Also, I suck at racing games.
If it's the feel of the physical controller that bothers you and not the way the software handles the shift AND you are handy with tools, do this:
Build your own.Except that rod he's using for a shifter and the plastic shift plate, replace that with a real shifter. If you need a 7 speed, you'll probably have to wait for the new corvettes to start showing up in junkyards. Shouldn't have to wait long.
You can do the same thing for the pedals, use pressure sensitive switches as I know the games on PC support them. No idea on consoles.
I mean, if you want a decent cockpit, you're going to have to build it yourself. Plans are available online.
