I was driving around the Daytona Road course working on a setup for the HPD ARX 01C prototype at iRacing the other night with my team mate. We were talking about what our cars were and weren't doing, ways to improve their handling etc. We then got onto discussing the subtle differences between the same sim racing setup being used by two different drivers, with different steering wheels and different styles (we have the same brake pedals).

Some people share their sim racing setups with others via the iRacing ingame forums, whilst other drivers like to keep what they drive a closely guarded secret. The thing that has always seemed slightly strange to me is that with the amount of different sim racing hardware, brakes and steering wheels available when people share a setup they never mention what specific equiptment they are using. Coupled with this the Force Feedback (FFB) number that you run in the sim will also be relevant.

If you drove a car with ingame FFB at 12 and then drove the same car and setup with FFB 1 they would have a different feel to them, generally weight to the steering wheel. Other symptoms with lower FFB might include oversteer, due to their being less resistance when you turn the wheel, but then again it all depends on how your FFB wheel works, different makes and brands run their internals in different ways.

I think that as sim racing is driven forwards people will start to become slightly more aware when sharing information to give more background on the subject. I believe that nearly all the time my team mate using a DFGT steering wheel has his iRacing FFB at a figure 2 higher than mine and I am using a Fanatec 911 GT3RS.
