seems like the porsche gt3 is just round the corner: iRacing will be down for maintenance next tuesday, 10th jan, from 14.00 gmt. this should mean the porsche will be in your garage by tuesday night
Also an optionMe thinks it's going to be maintenance for the Road to Daytona and the Daytona 24h events coming up in the following two weeks.
From what I know Porsche only at the end of the month.
