Vibration or wheel hopping?

[ShaneNg]

Hi all,

The car is a 91 240sx SE with Hicas and VLSD. I took it to the track 3 times now. Twice for auto-x and once for lapping the track. Under hard acceleration out of turns, I can feel the back end of the car vibrating. I almost feel like it has a locked rear diff. After sharing the car with someone else, I ws told that it can be yhe back wheels are hopping. What is the most common cause for this. I have checked all suspension components and everything is still tight. Anyone else has similar experience??

Thanks,

Shane

u probable have bent wheels or out of round tires or bad struts or mounts. it could be anything. those are the things i would check first though.
