Pulling to the left .... and rear speaker

My 166 is pulling to the left, I had it in to advance over a month ago and had all wheels balanced and then the car tracked. Brought it back to them as it has been pulling left over the last couple of weeks and got it retracked but it's still pulling left.
Now I only started doing decent mileage in her over the last couple of weeks so it could be it's been like this since I got it.
I have of course checked the tire pressures and have been keeping them at 2.3bar.

Any thoughts?

Also I need to fit a new rear left speaker, any brief comments on correct way to go about changing it. It's no as simple as it appears and I think I need to take out the rear seats but don't know how....?

Maybe the tyres - one of mine would track left over the camber, but the fix was to replace Michelins with Pirellis. The pseudo tech was that one of them was "out of true", so I suppose a knackered rim could do the same. Short of that it's a bent suspension arm of some description.

Who is doing the tracking?

I had mine done at a tyre place and it was awful. Took it to my dealer and they said I had Sports suspension set up or something like that.

Anyway, they said that tyre places will only have the settings for a standard 166 set up. Got it back from the dealer and it was perfect.

it cost £40 but thats better than keep scrubbing out new tyres and having pulling on the steering.

Thanks guys

Its Advance here in Ireland, just like the Kwik Fit guys.
Cost €95 for tracking and rebalancing of all four wheels.
