[kentyboy 0]

hi all!,relatively new to this corrado lark, recently purchased a 1990 tornado red 1.8 16v rado,overly happy with it,been lowered 40mm,running 16''borbet c's,discovered that the rear tyres are scrubbing out on the inside,problem being yoki's can get a bit expensive when having to keep renewing them,just wondering if any of you in corradoland can help me with advice on setting the back end up,as it looks like a fixed beam to me!!!!! :roll:

There is a small adjustment on the mounting bracket slots but this wont alter the camber, the only other option would be to shim the stub axle, I would seek advice from a specialist 4 wheel alignement centre.
