Wobble from 40mph onwards

Been a while since I've been on here so thought I'd give you all a challenge :)

Did a rally last weekend and I noticed from 40mph there was a very big wobble/vibration getting worse as we topped 70mph.

I have swapped wheels over incase i had a dodgey wheel but it's not that.

Anyone had this before? I reckon its either the wishbone bushes OR the right engine mount bush.

edit: sorry, forgot to mention it is just from the front-right hand side
Hadn't thought of that...

I don't have much luck with CVs at the moment. My Civic needs them replacing and now thr Micra.

Ah well. Got a new set of bushes on the way so will try them if not, CV joints it is
