Have you tried the Spec Racer Ford John? I'm having much fun with that at the moment, inbetween Radical races. The FFB on the SRF is really very good, I prefer it much more than the soft power steering you get with the solstice.
Funny how the Radical has become popular all of a sudden now that they have cut the schedule down to 2 days a week.
Tristan have you tried the Indy car? I really think you would like that. It's the only car in
any sim that i've tried that actually gives you the feeling of speed sensation, that thing is bloody quick with excellent FFB through the G25/DFGT. I run a few laps of practice in it but am so far of the pace to run in the official races. It's a car that takes explicit dedication I think to be quick in it. The set up options are extreme, I'm surprised they haven't included adjustable torque setting for the wheel nuts!
If you want to try it or any other cars then give drop me a PM and I'll lend you my account for a bit of practice.
