Wheel hop
 

Anything out there to help with this yet?

I know '03 Cobras had major wheel-hop problems that were mostly solved with poly bushings.

I had a huge problem with this in my G35 especially with sticky tires mounted. Haven't really had a problem with the Z so far.

It's a bitch isn't it
 

It's a bitch isn't it. I could not believe how bad it was in my 6sp. When I test drove an automatic it didn't have the wheel-hop problem. But I guess that the lower RPM starts probably helps....................
:driving:

Yeah on my 7AT I haven't had any wheel-hop issues. I mostly attributed that to the independent rear suspension on this car. My last car had a solid rear axle, and it was a bitch to tune wheel hop issues out of the suspension, esp when stiffening up the rear anyways. It would always hop given an uneven launching surface of course.

I was at the drag strip yesterday and was fighting it all night long. Seems like you really can't get away from it unless you decide to just bog your launches. I've even had a little bit of it accelerating out of tight corners.

Just hoping there's a quick and simple fix like there was for the '03 Cobra IRS.

Last night was frustrating, though. Really wish I had a Ford 8.8" live axle and some ET Streets on my Z last night. Oh, and some really soft front springs.

Rear Diff Solid Bushing
 

I have heard that a solid rear differential bushing helped on 350Z's and G35's.

I wonder when we'll see this stuff out for the 370.

I think it's the other way around. My Mustang was really as smooth as butter on a hard launch, but the Cobras had and their IRS had a hell of a time putting the power down without the new bushings to help.

It could just be the design of the suspension, though, not necessarily whether it's IRS or a solid rear, because wheel hop is a huge issue leaving the pits in NASCAR and under heavy braking/accelerating at road course tracks. They have solid rears but use an old-school truck-arm set up.

I think you're right, I think it has more to do with the suspension geometry than anything else. On a sticky track with sticky tires some of the rotational force gets translated to vertical movement, and depending on the suspension this may allow the axle to be pushed up and compress the spring.

Don't know whether this is an automatic or stick, but here is some wheel hop (starting at the 0:44 marker):

Sounded like an M6. God I hate wheel hop.

has anyone broken anything from wheelhop? (for the 370)

Stick
 

Stick shift
:tiphat:

Right now I don't think the stock tires are sticky enough to really shock anything hard enough to break it. I'd be worried, though, if somehow I fitted some ET Streets on the back and was hopping like crazy. Those things will bite and could easily snap an axle.

I can tell you, the Corvette guys (particularly the '05 C6) explode rears on a regular basis from wheel hop. Poly trans/Dif mounts and better shocks seem to minimize this..

Yea i know the corvette guys shatter their LSD's. They have little lsd case braces you can buy, but I hear if the wheel hop is bad enough it still cracks the casing.

Well if anyone does happen to break/crack anything from wheel hop..let us know! :O

solid bushings on the subframe and diff will eliminate it. i have a 300zx which are NOTORIOUS for really bad wheel hop.

I had a 92 Talon AWD that would get nasty wheel hop in the fronts before I replaced the engine/tranny mounts with solid polyurethanes. After that I could shock the drivelive as hard as I could and it would be nothing but smooth tire squealin.

My 350 gets it bad too, especially if I shift hard into 2nd on a wet road. Pretty annoying actually. That guy in the video might break an axle or diff if he keeps doing that.

I wish ingalls would release something to fix this, I had a ingalls etd on my last car and I could feel the difference

True. But I had 75A Innovative mounts on my RSX which are pretty heavy duty with a torque damper by Ingalls and I hated it! the launch was perfect even with street tires. But for a daily drive I couldnt stand the vibrations after about 4 months. I guess you got to ask yourself what you want out of your car. Although the good thing about the torque damper was I could install it and unistall it before and after the track but the mounts still tranferred a lot of the vribrations to the cabin. I know a bunch of guys with only the torque damper and they say its just as bad as having the 65A mounts or inserts.

To me the vibrations were not to bad at all, the etd def made the throttle response better.
