Drag Racing with 800+ HP maybe.
I guess I'm not following why go to a full floating rear end for street or track use with <600 RWHP?
With a good housing from Strange or Moser and Quality 31 splined Axles, are you in danger of breaking an axle even on a road race track with our cars? (w/ a Tru-Trac, or Spool)
Even, "Hard" driving on the track (Road Racetrack) requires the driver to be smooth as not to disrupt the balance of the car.
Help me, what am I missing, other than getting one for the coolness factor?

Ty,
It's really only partially an axle strength issue. The horespower transmitting capability is not at all at issue. It has to do with the bending loads high "G" cornering exerts on the axle at the bearing. The Bearing (Bearings, there are 2) are much larger on the floater hopusing. This gives you the strength and longevity for those high speed, high "G" turns. It also gives you the benefit of changing center sections without having to pull the wheels off. (Assuming no center caps on the track) Pop the axle covers off, pull the axles and away you go. Circle track guys use floaters almost exclusively. Check Coleman, Stock Car Products, Winters, Franklin to name a few for applications. They can be made any length or offset. The down side is, I don't think anybody is making a street brake "Kit" for them at this point. Could be wrong. You will probably have to build your own "Kit". Hope this helps.
