I have similar mods and the same gearing as you in my m6 14 GT and last Friday was my first time to the track. I was launching at around 2000 rpm feathering the clutch off the line and had no traction issues. 2.2 sec 60ft. wasn't good but t still ran a 12.9 @ 112 so I was happy.
And don't do a huge burn out on street tires the guy beside me on my first run did this the dumped the clutch @ 4000+ rpm and almost hit the wall. Then repeated the whole process to a t on his 2nd run and the outcome was the same.
But just have fun and follow track etiquette.
