Re: consequence's of wheel hop
It is avoidable. Their's a list of cure's you start to work. But, that doesn't mean the aftermarket is on line to give you all the things you'll need to work the list fully. Their may be more things then I've listed, I'm just mentioning the things I've seen used to cure wheel hop.
1.Stiffen rear suspension bushings with poly one's
2.Same for engine mounts and tranny mounts
3..Install struts with more dampening power (that would be just a 350Z away) I can't argue stiffer springs to, for curing wheel hop, but IMO, the car's needs them anyhow.
4.Install a pair of the rear traction rod's that minimise or correct rear toe. (These are really sold to bring rear toe back into spec on car's lowered more than 1". But in chasing the elimination game, I'd try them anyways.)
Thing is, I have never seen or hear of anyone else's G35 or 350Z doing this. But, now that I just ran a search on freshalloy, some threads did come up on "wheel hop"

(Gonna go search my350Z.com now)
I wonder if this is a freak thing related one spot that has strange unusual pavement grip properties.
I have another idea, thinking out loud. What if this is caused by a given road surface's high grip level. Where it is caused by the viscous limited slip. The system works on shear forces. I wonder if the grippy surface is exceeding the force that the viscous fluid can handle for a moment, where it lets the tire spin for a second, then the fluid locks, then spin, then lock. Remember the system reacts to a spinning tire, THEN it locks up, but it has a limitation on how much force the viscous fluid can handle.
Any time I've broken traction, I've never had wheel hop, just to say it.

Re: consequence's of wheel hop
Watch that HOP when burning out on an irregular or washboard road surfaces...I've see differentials blow apart on cars with aggressive, look at me burn out wheel hop. It's called blowing up the pumpkin. IT happens and you loose the rear end differential easy.

Re: consequence's of wheel hop
I really can't see the differential blowing up. I would say the axle shafts would give before that. I go offroad and run automatic lockers front and rear and the ring and pinion never gave even with wheel spin and big tires.

Re: consequence's of wheel hop
Wheel hop is actually a fairly violent action that seems to be inherent in many RWD cars with independent rear suspension.
The G35 coupe and the 350Z are known to do it, from what I've seen.....
Even the Mustang Cobra did it in 99, when IRS was first introduced on the Mustang.
From what I understand, wheel hop is caused by the"windup" of the axle shafts while not remaining ridgid as they would in a solid axle design. The force is "released" only to be retaken again by the spinning wheel... over and over again.
One things for sure-- it aint good for your rear suspension.

Re: consequence's of wheel hop
Yeah this happened to me a couple days ago late at night! (twice)
I was turning into a road that had a 15+ degree embankment that assisted drivers going fast on this semi-90 degree turn... well me late at nigh no-one around decides to take it at over three times the speed limit "not very smart" speed limit was 15 i was going about 55-60mph.
I am not sure if it was some small bumps i hit or what but twice in the turn my back end popped up and lost all traction!
Luckily VDC was on! and it sure reacted quickly... whew
It was great "stupid" Fun!!!!!
Peace,
Fun, semi-safe driving to you all ...
