As you may know the anti roll bar links fitted with the FK coilover kit for the astra are shorter than the standard VX ones.
Just thought i'd let anyone with this kit know if you need to replace the anti roll bar links they are nearly the same as the ones fitted to a standard ford focus (the alloy type). you will need to reuse the anti roll bar sleve fitted on the FK anti roll bar and would be best to fit them as apair.
hope this helps someone dunno..
