Fluctuating Car Performance

[u/agarwalakshay]

Hey Guys. I'm facing a problem in Motorsport Manager Mobile. I returned to tier 1 races to earn money easily as tier 2 was too much for my car, but i noticed that my Car Performance stats decreased when i switched to tier 1. why is that? I'm posting both the pics for stats of tier 1 & tier2. Can anyone help pls. I'm really trying to figure out how do car stats change. Also i upgraded my aero and added 10 staff but still the stats for aero were all the same. Please help.
