Diff Hop

[tbblitz]

Just after some ideas on how to stop diff hop in my vs spooled car.
if its wet and i nail it off the line it bounces so bad.. in the dry it never does it.

what are the bushes like. i hear the top control arms have alot to do with diff hop/chatter, especially if the bushes are worn.

Is your car lowered too? Adjustable upper control arms will reset the angle of your diff so your uni's don't work so hard.

the bushes im not sure i havent even looked. where should i be looking?

yes my car is lowered 3inchs or ultra low kinds hight

the top control arms are the 2 arms that connect from the top of the diff to the chassis about about 25cm long from memory. check all your bushes whilst your there though. sometimes it paysto fit aftermarket adjustable ones so that you can correct the pinion angle as well. some come fitted with a spherical bearing on one end which allows the suspension freer (spelling??) movement through it's range of motion as normal bushes can bind a little. also if you haven't already i would recommend nolathane type bushes, they flex/move less to maintain better suspension geometry

do they chop out as easy with a spool those nolathan bushes

Just a thought, arent we forgetting its IRS??

it could be but it could also be a trailing arm setup. not all VS commodores are IRS and seeing as he's asking about diff hop/chatter that's what i'd assume.
