tracking may be out, but more than likely be the fact that you have lowered the car 25mm, as this will give you more negative camber, which is ideal for cornering but a pain in the arse for tyre wear cause it will make the top of the wheel sit further in, which means it is wearing more on the inside edge, hence the baldness mate , ask for it to be tracked up again to check the front camber angles, plus your front toe angles aswell.

You can remedy this problem if you want by speaking to someone like Zoo Motorsport, as they can supply you with eccentric top mounts or adjustable lower arms, which would allow you to set it up the camber angles properly, although they could possibly advise you on a cheaper option as the other gear is quite expensive mate.
Give them a bell, and see what they say mate!!!
