It look like AS is dying but I hope some gentlemen take a look at my humbly request. I request Crush Gear Turbo & Nitro, the one shared here or nyaa is dead while the nitro on nyaa is very LQ.
Alhough they're rare on the internet, they're still available on Bandai stream as unlimited subscription but they got region locked. LINK
You can actually use a free trial account, so once you're done with ripping you can cancel the subscription. If some have a time and know what to do or experience riper please rip these series.

Thanks.
