I asked in FP comments on the 2015 Mustang warranty piece (thanks all for the 200 recommendations! Wooo!) but got no responses, so here goes again. How does an IRS-equipped Mustang do burnouts without massive wheel hop? I thought that was one of the big issues with ind rear suspension? What sorcery did Ford resort to in fixing this?

Same way carburetors work.

Wheel hop isn't really tied to unsprung weight or similar alone - it's a mix of different things. Low unsprung weight + ability to move forward and backward + poor damping + flexing of components + other things. If you try to burn out with something featuring really cheap shitty leaf/hotchkiss setup, well...
I tried to pull up the Oppo post I wanted, but it's gone bye-bye (despite being shared to the FP in December). Just look up "holden axle tramp".

Limited slip diff would help I believe.

Well I know the GM team curbed their axle tramp issues with the 2nd gen CTS-V by using asymmetrical axle shafts (diameter not length). Subsequently all GM high-po vehicles use this trick now that was originally thought up for the C6 corvette.

limited slips don't effect axle hop, its all in the suspension design

Interesting. I guess im not too familiar with axle hop and what causes it..

Differential equations.

As far as i know axle hop only affects live axles

I was referring to wheel hop, which after reading a bit seems pretty common in cars with IRS. Got some good responses though, which answered my question.

Wheel hop is simply a type of damped driven harmonic oscillation. Any engineering graduate should have had plenty of practice with the differential equations that govern this.
This is the likely culprit. This equation gives a sinusoidal input for the oscillations. Engineers would assume sinusoidal input to account for drivetrain windup/unwind. It tells you that you have to reduce the amplitude of the sin wave input (stiffen your drivetrain) and increase the damping coefficient (better shocks, yo) to reduce Mr. dx/dt (the hops).
