Well, considering XRG is a rear-wheels drive and thus slips more easily than say XFG, it's hard to make setups like that. And if it is possible it will make the car much more slower due to the ridicously increased grip. I'd say you should start practicing with the setups you have now, the truth is you could go much faster with slippier setups.
And, in case you haven't noticed it yet, rallycross is all about getting sideways and drifting on dirt.
It has been a long time since the concept of the series was invented back in April, but now the wait is almost over! Just a month remaining and the lights shall go off for the first time!
The graphics are better in AC already in my opinion, although AC doesn't fully support FFB yet so yeah nKPRO is quite good. However the physics are difficult to compare as AC currently has just 1 car and track to test.
Rules are rules, and you have to go with them. No exceptions. It's unfortunate you registered just now and you will most likely not reach that amount of drive.
Tbh you should just stick to demo as it is since you clearly require practice (especially looking at your stats) so buying S2 would be a needless "diving board". You won't get any better by getting S2, you must train harder first.
Saying that racing is boring while you like it is just ridiculous, you need to get around that boringness since you still have a lot to practice to match the other faster demo drivers out there. Either way, if you really want to get S2, you have to buy it since your experience isn't enough for winning a challenge.
Nevertheless, even though you couldn't afford S2 yet, you should indeed practice with the demo license like Dustin said above. When you are faster than the AI's, you have a decent pace.
Cut me some slack here, it's my first event I'm taking part in, and more accurately the first fixed setups event as well. You can't expect that my debut would've been any better than that of FSR's...
