1. I currently have stiff 5 leafs. I am considering going to a drag type spring. Could that and traction bars get me some good 60' times, or are they a waste until I am puttingdown more power?

2. I know Alex's opinion, but would the extra cost for flex-a-form fiberglass springs be worth it over say, Calvert Racing mono-leafs?

Thanks!

You could pull one of your leafs out of the springs you have now and clamp the back halves of the leafs. Then run traction bars or Cal-Tracks with a pair of Rancho shocks, # 9204.

Already have the Rancho's, and since I have $100 gift cert. to Jeg's, I think I am going to get some Slide-a-Links. In a previous post, Alex said they are better than Cal-Tracs. https://mustangsandmore.com/ubb/Forum12/HTML/001349.html

Never thought of pulling a leaf & clamping. What kind of clamp would I use?

I never did the clamping deal either. You need some square "u" bolts the width of your springs with a flat bar across the bolt. You're trying to clamp the rear leafs together so they don't move. Allowing just the front of the springs to work. Not sure how that'd work with slide-a-links though.

But definately pull a leaf out, does your car sit jacked up in the rear?

Hey Steve, when I was talking with Travis at Caltrac he said to only clamp the rear of the leafs if you are trying to slow down the separation. My car was hitting the tires too hard then bouncing up and spinning. That's just one way to control it. I think I slowed mine down too much and need to either take the clamps back off or loosen up the rear shock setting.

James,

Yeah I agree, we can slow down the seperation too much with just the Ranchos set on 3 or 4 with traction bars. We haven't had to resort to clamping the rear of the springs yet. But it's a good trick to have in your bag.

The shortest will only give you a small change, the next one up will give you a little more change. I really can't remember which one I pulled, but it settled the rear end down where it belonged. Before pulling the leaf, everyone thought it had air-shocks on it.
