check the springs any way find out mine were trashed
both fronts had split off up the top of them so loss a whole coil
and iam running 17" with 215/40 so the gap was even bigger but have dropped the ride hide by 30mm all round on eibach springs
which has made it some what better
also wishbones and tracking will make the car pull to one side also
a dodgey caliper could cause the same problem too
