Last Friday, me and my friends did street drag race. Mine is M2 with FBO (no meth) and STG1 Turbo on BM3 custom tune, but on stock tire PSS 50% left.
My friend - M4 ZCP stock, on Cup2 new tire.
We just floored it from stand still without launch control, because DCT do not allow repeated LC. M4 ZCP is half a car length ahead off the line and I kept up until on 4th gear (170kph or so) when we have to brake. We did this like 6 or 7 times, same outcome as video below shows.
Cup2 tire really completes M4 ZCP. It is so planted, putting down 400+rwhp. M2 is supposed to have better traction stock for stock, but his cup2 is just like cheating...no spin at all and I had traction issue even with PSS heated up to 100F.
We believe upgrading to Cup2, I can at least tie the game or even have a slight edge.
