Start up noise

[ean8]

I have an 8v golf gti and I replaced my front lower arms and Arb bush and link with powerflex bushes 2 months ago ever since then on my first test drive I have a vibration when I start the car and move off and accelerate quick but at cruising speed and when revving there is no vibration.
 

To try and fix the problem I now fitted  coilovers and new top mounts and replaced the track rod ends had the wheel alignment done and 2 new front tyres then front engine mount

I have now ran out of ideas I can't see any thing hitting anything

Please help me

Engine doesn't move would a clutch cause this problem

Polybush will give more vibration than oem rubber

just been having a look and found the rear wishbone bush bolt is missing  i remember putting it in as it was a pain.

also should i go back to standard bushes on the wishbone.
