I've heard pros and cons...they're fine, just some tire chirping when in a slow turn.
Or...You can't park your car without backing up 10 times....
My question...how are they on an open winding country road, when you want to lean into the curves a little...
DANGEROUS ??? Way too much over or under steer....
How bout some feed back...pro and con..
Thanks.

You will hardly notice the difference in regular driving from a good posi Eddie.
A little squeal here and a little squeal there is nothing compared to the benefits of full time dual rear wheel traction. Remember that your cars primary performance function is straight line. Many stock cars use spools and or locked rear ends depending on the track.

Thanks Alex...now all I have to do is learn how to spell "Streetability"...I just looked at my post...
Another word I must have made up....
So rounding curves at a nice rate of speed is safe and OK...
That's what my wrench told me...also.

How tuff are mini spools, I've heard they mainly for cicle track racing...could they stand up to drag racing, or at least standing start launches???

Yes they hold up fairly well to drag racing. They will not be the weak link. The stock carrier will break before the mini spool will.

I am running one in a 4 spd '66 with a 9" rear and it has held up nicely for almost a year with 1000s of hard street miles and several dozen 1/4 mi runs in the low 12s with 1.7 sec. 60' times.. You get used to the tires hopping around turns after awhile. Just drive very careful on slick pavement. You can do a 360 very easily! Make sure you get a quality spool and pin that are made from hardened steel. There are some soft ones going around Ebay.
I use these guys:

Full spool is more expensive, and stronger and lighter by design because it replaces the whole iron carrier assy with a solid steel or aluminum housing (dirt track). The mini-spool only replaces the spider gears inside a single traction carrier. I've never put one in a 8", but I've been told they will fit and work. All you have to do is match your spline count. They will only guarantee them for dirt track use. As with any hot rod part, they will put more stress on your drive train.

Is this something that i can just take out the pumpkin and put in or do i need a rear end shop to align the gears? On a mild street car what is the longevity? years or months. also you say it puts more stress on the driveline componets, does this mean that my trans will break before the spool? Im dumb when it comes to (Ford) rear ends!

A mini spool replaces the spider and side gears (the guts) in your original carrier. A REAL spool replaces the ENTIRE carrier.

When you make sharp turns, the inside tire is turning faster than it should so it will spin or chirp. Street tires spin easy anyways, so it's not that big a deal. Good posi-tracs can do the same thing, but they let go eventually. A spool will always keep both axels turning at the same speed, no matter what.

If you have some mechanic knowledge and a Chiltons manual that covers Ford rear-ends, you can do it yourself. The only trick is adjusting the mesh of the gears back to specs. You can even tighten up a little slack in the gears while your at it. If your not sure you can do it, just pull the pumpkin, wrap it up so it don't get dirty, and take it to a good mechanic. They should only charge for about an hour labor.
