The Clutch Delay Valve (or my translation: pile of poo valve) would have probably stopped you from toasting the drivetrain or spinning the car out. It slightly delays a fast clutch dump exactly for these situations. I echo what others said before: I think the vibration you are talking about is one of:
1: DSC activating after rear wheels slightly lock up.
2: Wheels locking up without DSC (Car detected no adverse yaw but still skidded).
2: The clutch slipping due to the CDV.
Dropping the clutch into a low gear at these speeds applies a sudden braking force on the whole drivetrain to the wheels so something has to give! I also assume you were braking pretty hard too, which means less weight over the rear wheels. Low weight + High braking force = Locked wheels and potential spin.
In otherwords DONT DO IT. At the very least Heel-and-toe to rev match (youll probably need sport mode for this) or learn to Double-Declutch... And whatever you do, don't try to 'recreate' it - it is likely not a problem with the car and mabe something (someone) else!!
Happy driving
