Vibration from front offside when taking foot off gas

[Mav]

Just changed from coilovers to normal suspension on my mk 4 astra coupe (Turbo)

All if fine driving until I take my foot off the power and I get a strange vibration/judder from the front passenger side.

What could this be any ideas please?

Thanks

Sorry front nearside, was not sure where to put this as I have an incling it might be the drivetrain?
