The 23-year-old, of Thornhill, and co-driver Andrew Watson are targeting a solid points finish on Sunday ó despite having a handicap imposed on their McLaren 650S.
Wylie, who is the reigning GT4 champion, and Watson are graded ‘silver’ status drivers, which means the Von Ryan Racing McLaren is forced to carry 80kg of ballast.
The race marks only the fourth time Wylie has raced at Rockingham, and it is his first race of this duration in a GT3 sportscar.
He said: “The aim for Rockingham is to score some solid points after a difficult season opener at Oulton Park.
“Oulton was a difficult challenge due to the extra ballast we are having to carry, but hopefully we can deal with that handicap a little better at Rockingham and have a good run.”
He added: “Being a two-hour race means the need for refuelling and longer stints come into the mix.
“Rockingham isn’t one of my favourite circuits although I did manage second place in GT4 in last year’s BGT race there. A strong top-six is what we’ll be aiming for on this occasion.
“In theory Rockingham should suit the McLaren better (than Oulton) but it’s difficult to predict. Also tyre degradation, caused by the extra weight we’re carrying, over a longer stint must be taken into consideration.”
