| Think mine does this too, I think its the diff.
It bounces the back up and down if I proper boot it, also bounces as I go round a corner at 30mph or so. I've got Tein Drift Masters or something, and at the moment they're set as hard as they'll go. Fairly sure they're fine as they're not squidgy and the adjustment still works fine.
I haven't had the car aligned though, and the back wheels are in different directions, loads of toe in etc.
When it's sideways, it's fine!! |
