PS4S on my 911 seem to be performing well. Quieter, with good grip in the dry. Haven't had the opportunity to try wet roads. Consider these tires for your 911.

Made my Focus RS even a better performer than it already was.. Ready for the next Targa SCCA multi-event. Good for track events, autocrosses, and daily driving. Better than some full race tires I've had in the past.

Very god tires for the street and quite good on the track. They tended to overheat at track days and not quite as good as the Michelin Cup 2 for track duty. Excellent comfort, noise and wet grip.

Had 4s's for a little over a week now, hands down out perform all tiers I had to date. Theyou are better in cold temps by far than Pirelli p zero...Haven't listened for noise just yet.. Maserati

Excellent traction in dry and wet. In acceleration, braking and cornering. I have no idea how they would be in the snow and I won't be finding out. expect they wouldn't be good. Have snow tires

Best all-around performance tire, excellent in rain. They do wear quickly but that is understood with sticky compounds.. Hydroplaning resistance reduced quickly with wear, but still the only performance tire I'd trust

The P Zeroes on my McLaren 720S were way too slippery - minimal grip especially when cold so… I had some “sideways moments with them” (unexpectably!). The Michelin P4S has cured the “problems” - great tire!

At the suggestion of Sipan Tire, I put these on the XKR this time. In a word: Wow. Directional, stick like glue, comfortable and quiet. I was worried that summer rated tires wouldn't do well in March in Canada. It was all for not.

2015 Chevy SS. They make this 4000 lb four door feel like a light weight. Hooks off the light, great around a corner... Hands down the best I have ever had in the rain. I couldn't be happier with this tire. You guys did a great job with this one.
