The Quattro 8.4 Ti is essentially identical to the Quattro RX except for a more modest suspension system buffering the skier from shock.

These aren’t the reactions the IQ Suspension system was meant to inspire, so we expect Blizzard to suss out the source of its ills and cure them by the time you read this.
