Uh, okay. ^^
I don't add weight for the 60 foot, but just like adjusting air psi, suspension settings and fuel load to right spot. And for a modern GTO 6 gear, a 3/4 tank over the back end gets it just right.
I am sure you optimize your car.
Are you in the DH event this weekend? I figure a big hookin, truly fast GVR$ would be there. We could do this on the track.
