Nice server, good to see anything else than cruise/drift/multiclass nowadays.
But if I had an advice to give, it'd be: please, please, please, get rid of the random grid setting. It can throw away very inexperimented people up front and some faster bakwards. Result, the inexperimented struggle in the first few corners while the faster rush to the front carelessly, which inevitabely results in insane amount of incidents and some bad DNF rates.
So it would be nice if you could replace that by the plain last race result=grid setting, or Airio's custom grid placement by PBs. Or if you want to spice things a little bit, set up Airio in order to make it reverse the top X of last race, there's a way to do that AFAIK.
