Hey, go ahead and do it! I'd start out with a
Logitech G27 Wheel and a
Logitech G930 headset. The headsets are going to be needed to not only communicate with other drivers (and sometimes official if you're in a league or hosted race) but if you have any children around, they won't pick up on any naughty words. There's a reason iRage was coined in the iRacing community.
You'll start out in the Rookie Street Stock class, which only visits two tracks, USA International Speedway in Florida and Charlotte Motor Speedway in Concord, NC. There, your only goal should be to
get out of Rookie and into D Class. Rookie Street Stock is best described as a demolition derby where a race occasionally breaks out. iRacing puts a bunch of newbies into a race and yea, it's baptism by fire in iRacing. Once you get your D License, the world is your oyster. You can stay in Rookie Street Stock til you get your C Class and go straight to C Class Street Stock. You can go to D Class Late Model, SK Modified (my series), Legends class, or the National cars, which is really the K&N cars.
On the road side, you'd start out with MX-5 cars and you actually do get a decent schedule of road courses. You can stay in MX-5 series once you get your D-Class, or you can go to Legends Road Course, Mustang Cup, Global Challenge, Skip Barber, Grand Touring Cup, or the Spec Racer.
For me, I love the SK Modified and will probably stay in that series. I mean iRacing does have the Truck series, Nationwide (called Class-B ) and the Sprint Cup series, but honestly I love how the SK Modified cars handle, I love the small community that developed around the SK Modified and I just have fun on the short tracks. I
may go Fixed set-up Trucks, even though I'm not a fan of fixed set-ups, just for ****s and giggles. However, my main series will always be the SK Modified.
