Was wondering how would i position my rear trailing arms to get the best forward bite? Its a 84 monte carlo with stock trailing arms.

we run our cars at 6* down on the pinion

Racer 17... Is that simply a 6 deg angle on the pinion? What are the actual arms angled at?

there are about very many opinions on this. on if you go by the books they say no more than 10 deg on the uppers and the lowers flat. on mine last year i ran the uppers at 25 degrees pointed down to the front, the right lower 2 deg up, and the left lower at 25 deg up. the left rear of the car picked up about 3 inches under power and hooked up good on slick tracks but got pretty erratic on rough tracks. it also had bad wheel hop under very hard braking. other guys say it makes no difference and some swear by it.

trailing arms angles definately make a difference in the bite of a car pionion does not pinion angle primarily reduced wear on u joints and I know this has been debated over and over but if your suspension does what it's supposed to I just can'see the pinion angle making a difference

That's right Flat, pinion angle itself does NOT affect bite or traction. Here we go.

Before the pinion angle thing get's ugly, how are you guys adjusting your trailing arm angles?

myself i like to go with the kiss thery when everthing is lined up the way my chassis man likes it the angle of the pinion is @ 6* i'l just leave it at that instead of measuring 100 different anlge of this that and the other thing we use the angle of the pinion as a referance point. if you would like the mesure ment we use to get this we mesure 1 1/4 in forward and drill a new hole then weld washers to the arm also and cut off the extra on the top arms
