Get the 60ft down to 1.6x and you are into the 10’s. Try launching quicker to lower the launch boost. As soon as the flags light, let it eat.

Well done !

I have tried different roads, diff rpms. Even on drag strip sometimes it does that.
Is there something wrong with my car? It happens with wheelspin or wheel hop when launching. I have stock 20 inch Michelin 4s tires.
I am pretty sure e63s does not do this.
If you had a JB4 you could limit boost in 1st gear at the launch to reduce the spin, I think BMS did that for their best times.
