In a 3300# Street Stock, do you guys think there is a performance benefit to using a full spool instead of a mini? I'm building a 9" for our car so I can buy the correct gears and run the glide in high, so this is the time to build it right. Any thoughts?

In my book, any time you can cut weight out of a rotating assembly, it's a good thing.

Will you notice the difference of a full spool? Doubtful. But do this sort of thing 10 times, and it'll make a difference.

If your building a 9" from scratch, take a look at the lightened ring gear too. I think Speedway carries them.

I was interested in the lighter version of the spool as well, but wondered if there would be any risk of failure or are they plenty strong. We run DOT tires, but the car is heavy. I've never run a full spool, so I don't know how much abuse they can take. Also, we don't run over 380 or 400 horsepower with our rules. Anyone have experience with those cut-out lightweight full spools?

Well, I've run a lightened steel spool since the beginning of the year, with no problems in a 3000 lbs racecar. I was told to stay away from the "ultra" light spools, as they were more suited for a Modified.
