Default 1989 Mustang GT, How Do I Adjust The Roll Bar?

i have an 89 gt that has an anti- roll bar on it. in my 85 bracket car the suspension is set up where the car is slightly leaning to the left and when i leave the line and go down the track it is level. it makes the 60' dead on everytime and it leaves straight and the same. my question is it better to load up the driver side where it trys to pull the car up level or load the passenger side up so when the car torques up off the line the suspension it doesnt have anywhere to go. its running high 11's low 12's with 60' in the low 1.70 and not really too cosistent yet. we are still tuning on it and tweeking tire pressure and timing ect. but it will probably end up around 11.85 ish.leaving off the footbrake it doesnt have a t-brake

If it is leaning it sounds like a bad torque box. If it is u need to get the torque box reinforcement kit to fix it.

U need to make sure he was not just trying to unload a headache on u. I don't know of any racers who want the car to lean and not go straight down the track but people do like to do different things. Now if the car leaves straight then that is fine the car just has a lot of body roll to compensate for.

i understand what you are saying, and that is not the case.it may be different around your tracks but there are a lot of cars that lean on the drivers side around here. i have even seen people with mustangs drive to the track and air up the passenger side air bag ,drag race, let the air out and drive home.maybe its because one of my cars leans that i notice it

I way we setup a backyard drag car is to put some old 4 cylinder springs on the back, new stock springs on the front, take off the sway bar from the front, and put drag shocks on; or for the really cheap guys really crappy front shocks to help the front come up faster.

i have my anti roll bar setup similar. but i took the air bag out of the passanger side once i got the anti roll bar. but i have it setup so the anti roll bar will stop the car from squating to the passanger side. now when i leave it leave stright as hell. i run 11.80s pretty consistant with a high 1.6 sixty foot.
