How do you guys manipulate these in order to get plenty of forward bite? Most of these cars are not set up for that.

The two things you want to tame on any stocker are forward thrust and axle wrap up. Leaf suspensions are a lot different than the 4-link in how this is done.

In the GM four link, the best set up for forward bite is to have the lower arms approximately level while having the upper arms pointing down at the front on approximately a 15 deg. angle. Under throttle, the angle of the upper arms will increase the downward force on the tires as the axle tries to wrap up.

Another thing to make note of is do not concern yourself with the pinion angle of the 4-link. As long as it is approximately level, you'll be OK. Leafs twist a lot, and for this reason Camaro and Nova owners spend a little time making sure it's in line when they are under throttle.

For what it's worth...
