255s on 20" x 9.5" wheels on a Performance 3

Cup2s aren't as bad as you might think in the wet. I wouldn't use them in the winter or once the tread depth is below 3mm, but they are a lot better than the original Cup 2.

Curious what tire you're planning to put on?

michelin as 4 plus or 3 plus all season tires

Both fine choices - if you can get the newer Tire(the Pilot Sport 4 plus) it's a little bit quieter and rides a little bit better

Unfortunately the Pilot Sport 4 does not come int 235/35 or 245/45 for 20” inch wheels. The first available size is 255/35

Cup 2’s are fine in the wet (I previously used them on a daily driver in the wet UK!) but below 5/6c, they have no grip at all. What they do need is the correct geometry to get the best out of them in the dry, otherwise you won’t see much improvement over the 4S.
