anyones that pushed the car hard surely is aware that the car is quite happy to redline in 1st and sit there easily while the tires spin and one bounces.

so untill they come out with new bushings to reduce it. how horrible is wheel hop for the car? I dont mean to have it, but its just so easy to peel the tires.

should I be extremely careful to avoid it?

 

I've noticed it too, especially when drag racing the car. It is weird because it doesn't get wheel hop all the time, and when it does it ranges from light to massive. My first run at the track resulted in incredible wheel hop and I had to let off for fear of breaking something. My suggestion would be to let off any time you get wheel hop because it is very bad for the transmission and rear end. I think the tires are probably more to blame than the bushings. I had a similar problem on my '72 Buick and I thought the only thing I could do to fix it was replace the worn out rubber bushings with poly ones, but first I replaced to Dunlop GT Qualifiers with Nitto NT555-R drag radials and it made a huge difference. I plan on putting these tires on the Z if they become available, it should make a huge difference.

 

I had it happen when I had to get a fast start onto the highway. Kinda scared me, cause I thought I'd broken something. Then I thought maybe since the pavement wasn't quite flat, that that had caused it to happen. I think better bushings or new rear suspension members will help, as will grippeir tires.

 

Its a common problem on a lot of cars (mostly FWD and not RWD I would think) and I don't think the tires are to blame. (although new ones might help some? I dunno) New springs and struts on my Maxima helped a lot.

 

Its actually more common on RWD cars with live-axle rears...

 

It is very common on cars such as my '72 Buick and other A-bodies like the Chevelle/GTO/442. The common cures are poly or aluminum rear bushings, boxed or billet aluminum control arms and adjustable upper control arms, plus better tires. A pinion snubber also helps. I think a lot of it happens from deflection in the rear suspension, I know the suspension on the Buick deflects enough that you can watch it under hard acceleration, and you can see the axle move from side to side. Maybe it would be helpful if someone would take a video of a Z doing a hard launch to get an idea of what the rear suspension is doing under load. I think we should get a group of people together and talk to some suspension companies that know how to set up a RWD car and see if we can get some parts made. I know Global West and Hotchkiss make very high quality parts for a lot of domestics and Hotchkiss has been getting into the import scene.

 

Sounds like a good idea. It's about time to start getting some good suspension parts made for this car anyway right?

 

The Z32 had this as well... I always thought it was due to the anti-squat geometry used for the Z's suspension. It used rubber subframe bushings out back that were pretty awful. Later one of the guys at tt.net made some "additions" to stick back there on the bushings... squeezing them down. Heard it's made a world of difference.

 

I think that was Greg from Specialty-Z. I used to take my Z32 to him quite a bit and he showed me he made something like that. I'll ask him about it.

Yah, Greg Dupree. I think they christened him a saint over at tt.net, lol. I know he was working on some equal length manifolds at one point.

 

Living within 15 minutes from him has really been convenient when I needed any help with my Z32. He knew it inside out, he could probably work on it blindfolded. Any time I'd go to his place, there was at least 10 Z's parked outside the garage.

I haven't talked to him for a while, i'm curious if he's started doing any Z33 work... that would really be great!
