i have a very slow car, almost stock...a 97 civic ex coupe...and when i get to the end of 1st gear, or even burn out launching the car it seems to bounce sometimes. im just wondering what causes that. is it a function of the clutch/ axle/ tire? does anyone else have this problem? and finally, how can i fix this prob? thanks people.

its not a problem. what you're describing sounds like wheel hop.
I'm not sure what causes it (equal length half shafts I think) but its perfectly normal.

be careful, I've heard wheel hop can snap axles...

Soft rubber suspension bushings, as well as soft OEM engine mounts will contribute to wheel hop. If you want to lessen wheel hop, get some urethane suspension bushings and engine mounts(inserts also help a lot, if you don't want to get entirely new mounts). Radius arms will also help with wheel hop, although the geometry of the Z10 setups isn't exactly ideal.

thanks...this guy at work always makes fun of me for that. i can pull perfectly even with his camero in a race until 90mph or so when i pull ahead a bit. he still says he doesn't want a honda cause it cant do a complete burnout. ha

what we did with my 92 motor mounts was pull them one at a time, clean them, and fill the holes and cracks with silicon... let it dry and then fill the whole rubber piece with silicon. after, i painted the silicon/rubber mount black and clearcoated it... installed it and almost all my wheelhop went away. it still does it every now and then, but atleast not all the time... note on this picture they have not all been done yet.

Bad shocks and/or can also contribute to wheel hop. If the springs were cut to lower the ride, they end up being too soft. Stiffer springs, shocks and tires (lower profile) can all help.

that is totally true as well. fortunately, I am riding on stock suspension

i dont think that's the prob...im riding on tokico gas socks and eiback ground controls w/ a 2" drop and a skunk camber kit.

Sweet setup! That all sounds good, but you could still have a blown shock. Look for oil leaking out. You can replace rubber isolators with stiffer materials, but that affects NVH in a bad way. And because the driven wheels are also used to steer, there's not much more you can do to control FWD wheel hop. That's why I'd hope to find a blown shock, and fixing it solves the problem.

Another thought--a 2" drop might be contributing to the windup. The wheel climbs up, hitting the bump stop, which drives it back down... A little more suspension travel might help.
