Traction control issues after ventus V12's installed

I'm not entirely convinced that what everybody else has said is correct.

It could have something to do with your front and rear tires being 0.3" different in diameter now. Stock, they are 0.1" different at most. Such a "slip" between the front and rear wheel speed sensors (there is one on each wheel for ABS and VDC purposes) may cause the system to engage sporadically.

Give it a few hundred more miles like everybody else says. If it doesn't go away, you're going to need to get some matching diameter front tires.

This is true. I think the general rule is that you want to keep your front and rear tire diameters within 3% of one another otherwise it can throw off the sensors. It's mentioned quite a bit in some of the tire sizing threads.
