On this website, you can compare FL5 and FK8.
Honda Civic Type R vs Honda Civic Type R 2022 -> Duel 670010556 (zeperfs.com)
There isn't a lot of time for the FL5 for the moment, but that will change in the coming weeks.
It would be interested to compare fk8 and fl5 with same tyres. FK8 was delivered with continental, and Fl5 with Michelin. And tyres can make a huge difference on a lap time.
In France, my dealer think we will only have 20 FL5 in 2023 and 20 in 2024.
We will also have additionnal malus tax (12000 €) because FL5 is a polluter. On the last fk8 sold en 2020, the malus was 8000 €.
