For the helmet settings, leave the first figure as it is, the second figure needs to be higher to raise the helmet - try 0.0950 or higher, - if the helmet is too far forward or back, you need to change the third figure, for example -0.2500 would move the helmet further back than yours, -0.1500 would move it further forward and so on,
It's the same thing for the steering wheel, leave the first figure, the second figure adjusts the height so you may want to leave that, - as your wheel is way too far back, you probably need a plus figure, try 0.0500 and work from there, higher number moves the helmet forward, lower number moves it back
hope these help
