Cornering I'm getting DSC light action in the dash cluster and I can feel the intervention in turns where I never did before! My front to back diameters are identical currently.

Stock diameters are 25.8 f 26.3 r. A half inch difference.
With the conti's it was 25.8 f 25.5 rear with 275/30 and no DSC issues.
Now with new V12's 25.8 f 25.8 rear with 285/30

Why is the square (diameter wise) setup causing problems? And why didn't the Conti's which were actually smaller than the front?
