Many Michelin models are difficult to find. Supply is short in Canada. Was looking for Cup 2s for my 19 ZR1 but got shut out. No rears till maybe March. Called Tire Rack in the US. They have product and shipped it to me in 3 days! Sure, cost was a bit more but at least I’m mobile!
I put those same Nittos on my 08 Z06 and did a Pfadt Street Alignment. Didn’t notice any difference in handling however the wandering on pavement cracks was all but eliminated and they lasted over 50k km. Yes 50k and they were way quieter!!
