Sim Racing

I'm looking for some advice, it's been a few years since I was into sim racing (AC, PC2, iracing), now I'm looking to get back into sims - mostly offline at first. I have an older Logi G27 wheel & pedals and have recently moved to Linux (Bazzite).

From what I understand, these should work in Linux, however I'm interested in upgrades to make things better. The G27 is fine, wheel is ok and does the job for now (vs my skill level) but the brake pedal is my biggest issue in being consistent.

It's been a while since I've been up to play on hardware, is it worth finding a loadcell brake/mod for the G27 considering the age of this kit, or is it better to replace the entire pedal set with something newer?
