Yep you're probably right. I've noticed a difference in feel between front and back. Front is softer, quieter and grippy whereas the rear feels harder, noisier and less grippy, complete opposite. It's going to be worth swapping the rears because I don't like the feel. It feels like the front is very pointy and the rears will break away. Not in the dry, more noticeable in damp greasy conditions than full wet. Tell you what, if you think an RX on Dunlops is bad you should try a Jaguar XF 3.0DS on Dunlops in the wet. Scary in the wet even with all of today's safety aids. 600NM of torque flooding in all of a sudden made for an interesting drive at times
