Handling problem

[V8NHH]

Hello again what a fun filled 2.5 days ownership!!, have a concern that something not quite right with GTS-R No9 handling just got of phone with sjc and its new one on him ,so here goes. Tight right turns slow speed or slightly faster eg on roundabouts etc car feels very nervous/loose on the arse end yet round left hand tight bends / junctions all ok checked tyre pressures etc everything ok I could see was very surprised this morning when went to park and turned tight to go down next lane of spaces and back slide right out!!! repeated exercise turning left but no problems (its not led foot syndrome)
Any ideas appreciated
