You’re on a solid upgrade path, and the GT Omega Prime Lite is absolutely strong enough for an R9-level setup. On the seat side, I’ll say this: I really like the Trak Racer Rally seat. It’s comfortable for long sessions, supportive enough for serious driving, and works well for sim racing without feeling overly aggressive. It should be compatible with the Prime Lite using either Trak Racer or GT Omega seat brackets, since these aluminum profile rigs generally share the same mounting standards. Overall, it’s a safe, well-rounded seat choice that won’t hold the rest of your setup back.

thank you a lot, I will consider it in the future
