The 215 x 15 Michelin TB15 is the cream of the crop for the front end of a Stratos rep.
The new P7 Corsa might be on a par, but I doubt it's any better.

A Hawk needs to have the correct offset on the front wheels.
That, and any 'give' in the front tie bar (tension strut) bushes can make a Hawk dart about on the road.
So much so that it will be an awful thing to drive.
