New clutch installed and bad wheel hop?

Check for broken motor mounts. Open your hood, put your foot on the brakes firmly, put the car in gear and begin to carefully let the clutch out. Look to see if the driver's side of the engine is lifting up excessively. Put the transmission in reverse, let clutch out carefully and see if the passenger side of the motor lifts up excessively. Replace as necessary.

Disclaimer: don't drive around with the hood open.
