Do you really need 160mhz channels?
More width channels give less available channels without overlap. What can cause more interference.
So with width channel use, your client can show you higher connected speed. But the cause of interferance will sends more of tcp retransmissions and actually drops down the goodputh speed (real speed).
Also care that with160mhz channels you also use DFS channels that can cause AP’s are stop sending when a airplan/weather radar etc. is detected.
Beter stay at lower channels for more stability. But all depends on the envoirnment
