The steering feels a little too light to be realistic (at ffb 16 anyway) but other than that i like the way it drives like an old capri or escort !
Do you need to ramp up the steering force for some cars in IR?
Some, yes, but some you just have to learn to cope with very subtle steering forces. The Late Model is much better in that regard - if you haven't tried it yet, grab the "Late Model Road Baseline" setup from the official forums topic above and go get stuck into the 24 Heures du Fun Late Model/Street Stock/Legends series at Road America. The races are chaotic but fun if you're willing to adopt a 'drive to survive' mentality for the first lap.
