iracing is probably the most serious racing sim, with many competitions etc.
So if you are keen on paying for it monthly, then you should be keen to get a racing wheel setup, which is good because they are pretty cheap now.
I recommend you get a
Logitech G27, around $265-280 at pretty much all computer stores now. That link is from a store in Vic but check
this site if you're not in Victoria and wish to find the best price for one in your own state.
I've owned one for the last 2 years and it's been an incredible wheel, definitely recommend it.
