Subaru is hoping to smash its own record for the fastest time around the TT course on four wheels.
The rally team is here with a car which will be driven again by Mark Higgins.
The Manx driver was behind the wheel when the 115.505mph (19:37:47) record was set three years ago.
Mark put in some practice on Saturday but told Chris Boyde that he was feeling frustrated:(Play media below)
He will make another record attempt today (Monday) and again on Wednesday.
