Simon Andrews was quickest in the Superstock class, William Dunlop in the Supersport.
Conor Cummins decided give tonight's session a miss, to give the hand he injured at the North West 200 more time to heal.
Meanwhile in the sidecars Dave Molyneux - the 14-time winner who sat out last year - went round at an average speed of 111.86mph.
Two sidecar crews - the Birchall brothers, and Glyn Jones and Richard Murphy - were air-medded to Noble's Hospital after accidents at Brandywell and Keppel gate respectively.
Both pairs were conscious when they were taken in.
