The ultimate sprag bolts into the case through the rear support and two additional bolts. That helps hold the outer cam in the case opposed to the stock set screw and press fit. The 16 elements also have more holding power than a 12 or 14 element bolt in sprag. Not that the 6 bolt 16 element sprag cant fail, but it’s considerably stronger than a stock sprag or a 4 bolt 12 or 14 element sprag.

I don’t blame you for wanting steel. That is the way to go in my opinion especially in a street car.

It may last longer than you think, especially with a lot of street use.

Thanks for clarifying about the sprag stuff. I knew about the Ultimate Sprags, but I guess I was just thinking of the plain bolt in units.

Yea this is a street car first and foremost, but I would like to run it in a few of the daily driver no prep classes here, so it will have to withstand some actual racing abuse.

With my luck, I will barely get it running this season and not get much racing on it, so maybe next winter I can get the trans built up properly.

What do the parts you listed in the beginning of this thread cost roughly? Not labour, just hard parts? I have done all my own transmission work up to this point, so I think i'd be fairly comfortable installing better parts so long as no special machining is required to do so.
