How much a equipment can slow you down

Started iracing about two weeks ago, and managed to get some podiums and two wins in the mazda MX-5. I own a G920 and the most basic rig i could find. But this week in Lime Rock Park is being horrendous to me, always finishing between 7-9, and my irating is dropping like water. Can’t pass the 1.06.300 on the qualy, and i feel the pedals is the most limitating part of it all. I know I’m not the best driver, but being almost two seconds from the ideal lap always, feels like i’m shit.

Edit: after the comments, hopped on the sim and been able to drop my time to 1:06:029. Unfortunaly it was on pratice, but gonna keep trying.
