bar angles

[fast hot rod]

what are good bar angles to run on and 4 bar car with and 604 crate

Here is a good starting point.

....LR.........RR
U..26*.......16*
L...6*.........7*

Raise the LR upper one hole for slick. Drop the RR lower a hole or two at the most to tighten up entry if needed. I like to keep some angle in the RR lower at all times.

Put a chain on the LR so that you get to 45* on the upper bar angle at full drop when the upper bar is in this base setup of 26* at ride height. When you raise the LR upper a hole for the slick it will go past 45* at full drop of the chain and that is perfectly fine. I rarely adjust the chain length.

The bar angles stated are good starting numbers. However I disagree with the adjustments provided. There are too many variables car to car to suggest such changes. I highly recommend measuring out the rear suspension to obtain correct geometry. When proper geometry is obtained, you can make changes at the shop and determine what will work best for each situation. I also suggest not letting the LRU link go beyond 45 degrees of angle at drop. Excess of 45 degrees promotes chassis hike rather than forward thrust.
