Yannick:
Welcome.
The wheel rattling, its a design feature of RF2 that kerbs## and flat spots cause a vibration.
The G27 has plastic bearings that dont like the high frequency feedback. The adjustment is "FFB smoothing" increase this. There is no way to turn off flat spotting, get your brake settings nice (force, distribution), get tyres warmed well before braking hard and drive well!!! Its the only way to not flat spot. (rememeber Nico Rosberg at Sochi). ABS will help a lot of course.
## Edit, there is a setting in player or controller (not sure which) json file that lets you adjust how much of a bump you get from kerbs.
Car wise, a few thoughts:
Open wheelers:
Skip Barber is a great trainer, gives (more) amazing feel now since the update.
BTW watch the Skip Barber video on Youtube called "Going Faster". Its about 90min.
HERE What works in real cars works in RF2. You could do worse things than say 200 laps of Limerock in the skippy. You will find skills that you will use everywhere else.
Watch the Video again (all the way through this time
)
Dallara DW12 Fast , fun, pretty easy. Great car if you are getting a bit fed up and just want a blast. Default set up is very under-steery so it nukes the front tyres. Make sure you pick the right aero package and make sure any AI do as well by clicking "force setup". Otherwise they will arrive at Suzuka with an Indycar aero pack.
FR 3.5 2014 spec. IMO you are getting into proper cars here, its fast, bit more demanding good feel. Again set correct aero pack , its (rear wing only) locked once you are in the pit garage.
Formula ISI. Fast and demanding on set up and driving style. It will take quite a few laps to come up to speed. The FSR car is that car with slight changes. The main stuff is the same (power, weight). There is amongst other things a little less dirty air effect and the brakes will take higher temps.
The teams that you see on FSR will often have 3-5 guys working on set ups on this car.
Formula 2 (modern). I'm not a fan, not much feel and caster is locked so you cant increase it to get more feel in the steering.
T
he ASR 1992 cars (my preference is the 1.81 version). They are great.
Historic Formula cars Most are awesome, huge feel, great fun. Brabham was updated recently.
Howstens: Great fun, great feel, need patience and a subtle throttle.
Tin Tops: Great Cars
Spec Miata, Huge feel from this little car.
Ferrari 458 Challenge Same and limited set up options. Rewards good driving.
Blancpain Endurance Series (BES 1.0). I love the 911 GT3, VERY authentic. The rest are great too. the 911 GT3 is bugged on some tracks and hits hidden bumps. If you are at one of those change cars.
The ISI GT cars Camaro, Vette, Nissan GTR GT1
There are set ups to many of these cars
