    Post 69 skylark / rear axle bars set up best 60'

    I have a buddy setting up his 69 buick skylark for street strip use , has a 12 bolt out of a chevelle in it with adjustable upper and lower bars . He is wanting to get the lower bars parrelle to the ground for the best performance at the strip (60' times and to make it stop unloading suspension) .He has air bags now ,has roll control (not installed yet ) ,has around 650 to 700 horsepower , th400 with transbrake /5400 stall conv., 28/11.5 hoosier et drags.------ The main thing is the chevelle guys say to get the best hooking and maintain it you must get that lower control arm parrelle to the ground .Any help please ?

    Before you go "level", I would learn a bit about the effects. Here is a short article that should help:

    new changes

    Now the tires are 295/65 r-15 m/t drag radials with the roll control from TRZ motorsports , 3" axle lowering blocks in the mail for the lower bars .This is getting the anti-squat factor around 176 % .He will be testing by the week end to see the difference -- before the anti -squat was negative 45 % .Will let you know .
