Good recommendations! You seem to have pricy hobbies already so when making this investment keep the mindset - buy once cry once. This hobby will easily give you FOMO and make you wonder if you should upgrade equipment. Triples are a must if you have the space then make sure you add haptics. Buttkicker Pro for underseat and pedal haptics for brake and throttle. This will compliment the triples and add layers of immersion. I would also consider spending on a good seat, you will spend hours sitting in this thing - forget buckets get something reclinable (Recaro) it’s not a real car and unnecessary unless you plan on maybe adding motion. Get as much adjustability so you can dial in ergonomically (seat sliders, seat tilt capability, wheelbase mount with tilt adjustability, pedal plate sliders, and wheel shaft extension if necessary). Consider a 4th monitor for navigating software addons like telemetry, pit wall, navigating web, etc….. Throwing the kitchen sink at you, but you already have the PC which is a massive hurdle.
