Hi,Just wondering if many people have had trouble with diff bounce when starting at the drags,i have a manual irs clubsport,A suspension shop has told me it is probably a bush that holds the diff to the body at the back.cheers
It's called tramping. With the older cars it would be a matter of some tramper bars to help stabilize the diff from moving. Maybe check your bushes and try different profile rims/tyres.
from what i've read its pretty much related to
-shockers
-springs
or
-upper control arms
usually, i could be wrong
check your control arm bushes, that will help a bit if they are worn, but more than likely your springs are too hard
mine used to do that when i got different tires it went away
