Unbeleivable, Great traction and stopping is excellent. Cornering is fantastic too. Although I do check in the rear view mirror for others that can't stop as fast.

 

Looks exactly like my 16" setup...steelies look *ok* on the black SS, but after a few weeks looking at them, may look for some winter rims for next year. You really appreciate the stock chrome wheels setting vehicle off.
Doesn't help as mine is currently debadged, so its monochome madness, minus the bowties.

Yes, notice an upgrade, certainly in stopping, as well.

Just hope when the 18"s go back on in the spring, I pay attention to the tire pressure warning light again...already, I don't notice the light on all the time.

One big downfall...they're noticeably loud. Never really paid attention to tire/road noise (and I have undercoating too) on any of my cars, but these are my first winter tires on any car, and their hard to ignore, noise wise.

 

Driving Hwy 401, 120 kph and only slight noise, not bad at all.
