advantages- full time posi

disadvantages- worn tires, broken axles, loss of control and the list goes on and on

general consesus is a spool does not belong on the street.. ither a locker or a limated slip only if you want both tires to spin

When you are driving on any path other than a perfectly straight line, the outer tire must travel farther than the inner tire just due to geometry. Since both tires are the same diameter (unless you have a dirt track car...), the outer tire must spin faster than the inboard to keep up. If you use a spool (or weld the gears), you've locked the two tires together so that they always turn at the same speed. When you go around a corner, one tire will be forced to drag or slip on the pavement (which is why it "chirps").

If the tire is slipping, it does not have traction. The result is that you now have one rear wheel doing the cornering instead of two. You are now twice as likely to swap ends. Note that I haven't even started to talk about what this does to axle shafts, tires, etc. Bottom line is that this is a bad idea.

"cheapest way to go" hardy har har


I run a Mark Williams spool in a Dana 60 on the street with 30X12.5X15 MT street slicks. I use coil overs with full ladder bars, 40 spline gun drilled axels and Richmond Pro gears. Car is 4 corner weighed and balanced. Never broke an axel or a rear end gear. (Can fire up the skins real nice also..)

Set the car/suspension correctly , drive responsibly, and learn their charactistics, then they are fine..

Drive like a squirrel and you will also, end up in a tree.. or mashed flat some where..

The swapping ends problem is real, even with a positrac. I had an instance years ago with my 70 Nova. I was tuning the car getting ready for the Wednesday grudge races at the local drag strip. I had made several hard launches on a country road. This one particular launch was hard, the car hooked up really well. Unfortunately there had been a recent rain and I hit a patch where the pavement was still wet. Before I could even think about it I was out of control spinning backward down the road. I wound up facing the opposite direction almost in the ditch. I can't even think of one reason I would run a spool on the street.

If you have an accident and the your insurance finds out you have a spool I don't think they will pay.

i think if your planning on using this vehicle everyday, in all types of weather, go with a limited slip. If this is a sunny day weekend warrior, spool 'er up, you will have to get used to the driving characteristics as stated earlier, but its not at all hard to control.... just use common sense and judgment

Spools were developed for racing and racing only. They are designed for straight line acceleration and they have no practical use on the street. Spools are dangerous on wet roads and are hard on axles and tires. Use one at your own risk.

My car is a prostreet car,14to1, 468 and a 5200 stall,Never broke a axle,dont scrub the rear tires and it drives just fine, in the summer I drive it all the time. As far as the wet road's, common sense goes along ways when your driving a hot rod. I usually dont think of jumping in my hot rod and driving around in the rain and I have enough common sense to be aware of recent rain before I go tearing down a road, Usually I will save that for the track.

Just like automods said, If your a weekend warrior,street/strip spool it, If your gonna drive it all year round then put a posi.

I know around here we have crowns built into the streets. I once drove a car with a spool around the block just to move it, it was totally retarded!
There is no way you could get away with that here...
