Use the proper gear. Do not use a joypad or even joysticks. Play with a wheel. There are racers out there who are even fast with cheap wheelbases but the more expensive wheelbases like Fanatec providers often give a better feedback and also channel the forces better.
If you invest in a cheap wheelbase and want to upgrade to something in the future replacing the pedals would be a good choice. Especially pedals with a loadcell.
But not only a proper wheel will make you faster, also the right seat position. So try to create a place that you do not have to disassemble all the time. Get the right seating position or eventually buy or create your own rig.
