I race a Chev Malibu and i heard that the pinio angle can change your side bite and help you get throught the corners better. I was just wondering what it actually does and what it should be set at.

pinion angle is a touchy subject on here. you want your pinion angle set to where when your on the gas you driveshaft is straight with the rearend. what it does is reduces the bind on the u-joint to free up power. the false feeling of forward bite when changing pinion angle is caused by fiction and binding of the u-joint because its taking power away. if you wanna increase bite you need to mess with your controls arms, springs, tire pressure, weight percentages etc. i hope this makes sense, i just woke up!

WITH YOUR CAR AT RIDE HEIGHT UNHOOK YOUR UP ARMS TILT THE REAREND TILL THE PINION IS AT 8 DEGREES YOU CAN USE AN ANGLE FINDER TO DO IT. ONCE YOU HAVE DONE THAT JUST DRILL YOU NEW HOLES IN THE UP ARMS AND BOLT BACK IN PALCE. NOT AS EASY AS IT SOUNDS BUT CAN BE DONE.

5eracing, From what i was taught pinion angle can help a little on foward bite as it serves as a line break.True pinion angle is a combo. of driveshaft angle & pinion angle. when on the gas & the pinion lifts it lines up with the tail of the tranny & formes as straight of a line as possible to use as little power as possible to turn the shaft.Have not heard where it gives side bite. Center of gravity height verses roll center height & weight height placement will give more or less side bite.Also angle on panhard bar,wheel offset& a couple of other things help. cd2

I run stock location and i run in the top three (if not first) just about every week. So it really makes no difference at all....
