Having recently had my front wheels balanced I am still experiencing will shudder more noticable the higher the speed.

No obvious wear in steering, suspension etc.

Any suggestions or advice would be gratefully recieved

I had exactly the same problem. Mine was caused by one of the front calipers sticking. Take your car for a drive and then whilst the discs are still hot [and obviously when you have stopped] jack up the front of the car and see how easily yours wheels turn. I had my wheels balanced on and off the car all to no avail and then by accident noticed the caliper.
Good luck.
