Another pinion angle ?

It's really a crap shoot.

I set my pinion at -4. My trans sits at dam near zero.

Tire affects the twist, rear gear affects the twist, springs affect the twist, track prep or the road your on affect the twist. Slapper bars, cal tracks affect the twist, how you drive normal VS hard launches affect your decision.

I run DOT drag radials with 4.88 rear gear on the street and that's where my car lives so I'm not dead hooking most times.

-4 is working good for my car.
