Yeah, the reason why the inner edges are wearing is because of the extra weight in the front, just take it to a garage and they'll track it for you (it's just a matter of turning a few bolts with some laser alignment tools on the wheels, as opposed to any specific 'spec' etc.) :nod::beer:
will do your handling and grip a world of good!!

Inner tyre wear if tracked correctly is a camber issue. If a tracking issue it is due to too much toe-out.

bang on!

Was the tracking done after you put the 2l engine in? It has to be done afterwards.
If camber is the issue (due to excessive lowering or bent arms etc) you can correct this with 'camber bolts'.
