Front tire size/Reaction Times/Mustang 5.0

[Bobby Fazio]

I have Eibach drag launch springs with the right rear airbag. Have 15lbs in but we didnt put that in until right before Q3 and it straightened it out a little but the sixty was actually slower. I have strange single adjustable shocks all the way around. I have subframe connectors welded in and am thinking about adding a 6 point rollbar to tie the car up some more and in case I want to move into M/SA. Adjustable chromoly upper control arms. Lower control arms are granatelli I think, but basically stock. Factory sway bar is in the rear. None in the front. Just picked up a used set of 24" hoosiers for 130 bucks so maybe I will try them.

Bobby,

Sound like you have similar pieces to mine. I run my Strange adjustable RR shock much stiffer than the rest to help the squat, I usually am at 30-35 in the RR bag. Same set up in my SSer. No magic and it launches pretty evenly now. I do use factory sway bar and 27.5 front runners. If I run a lot of weight in my P/SA I go back to stock rear springs with no problem.

www.teamzmotorsports.net makes dedicated fox-body stock location rear drag springs. Might be worth a try, I have one of their anti-roll bars, have not tried it yet. I have used the air bag...it is OK, at best. the TeamZ anti-roll could be bolted into the frame, you would still have to weld the brackets to the rear housing, I think that will fly in NHRA.

That bar would probably work great but there was alot of welding involved and that might be illegal. The air bag at 15lbs makes the right side of the car sit much higher than the left side at a standstill. Is this normal on these cars? Is that adding preload also? I guess scales would really help..

mine sets a little higher on the RR with the airbag also.

[fordteacherguy]

Right side higher? Now you look like a stocker! Yep, that's preload.

If I get the Team Z bolt in anti roll bar should I take the airbag out?

Yes. The adjustment will now come from the preload you put into the ARB. The bag is now useless.

Try doing a little research into what was/is available as far as spring rates. If you can find a heavier rate with the same height, put it in the right rear with the air bag.
