You can just peel the carpet back from under the top lip. Start near the hood hinge as you can get to the edge of the carpet there. Fold the carpet back and you can get access. There are also a couple of black plugs if you need more room. It might seem drastic, but it goes back just fine.

Mixing tyres on a Z3 is always a risk. Sometimes you get away with it, but mostly not. If the rears are good then I would get the exact same make/model on the front. Also look at front lower control arm bushes (lollipops). You can also play with the tyre pressure a little.
