I had also used a G force on my 2016 and the same. Didn't break but at around 2000km it had little cracks everywhere all around in the "cracks" so I replaced it with the OEM and kept the G force as a spare.
Within the Gates brand, only buy the Redline model. That's the best they offer.
Within the BRP brand (OEM), only buy the original belt with the part number ending in 364 (or 367).
However, the toughest belt has been proved to be the GBoost WBB302. Even a turbo X3 and an Outlander 1000R at wide open throttle were unable to break it.
