Need some input on settings for rear QA1 shocks at drag strip. I know for street driving that a setting of 8 was real firm and that 6 was still to firm and have settled in at 2 for everyday driving.
Other than trial and error is there any prefferred setting to start with at at the strip?

Chuck,
My guess is that no one has done much if any testing with the QA1 (HAL) rear shocks. You might go to one of the Grand National lists as they have been using these for a while. In general I would try them as soft as they go first. If you don't get any wheel hop on this setting it is probably the best for weight transfer.
one caution - It is very hard to evaluate individual settings without making a large # of identical passes. To start I would look at just your 60ft times and keep everything else you do in terms of burnout, staging and launch RPM the same.
Good Luck and let us know what you discover.

Generally the Impala likes stock shocks on the rear for good 60' times, which would be the equivalent of #4 on the HAL shocks.

Hey, I remember that ad slogan! "Let your fingers do the talking"

Now I suppose someone will spout off that I got that slightly wrong :(

You'll have to experiment for yourself & see what seems to work for you.. There's lots of variables to consider like what rear springs you have vehicle weight, front springs & shocks etc... Also too much "squat" is no good either. Whatever energy is used to compress the rear suspension is not being used to plant the tires or push the car foward.

What works on my car with ST rear springs is "6" on the drivers side & "8" on the passnger side. since I put these shocks in I have left the air bag in the passenger side spring at 0 psi. With a bone stock engine & drag radials I've gotten a best of 1.773 60'
