I'd personallt take the PSC anytime over the RA-1s.

These are track tires only. I replaced Toyo RA-1s with the Pilot Sport Cups. Once you get the pressures right (go to the Michelin website and believe them) these are far superior to the RA-1s. They are peaky, but you have to trust them, there is plenty more there than you think. I would say the RA-1s were more linear. The Cups wear very well. I have 6 days on them and they will easily get 6 more. Very good value. My lap times are 3-4 seconds faster with these tires at Road America and Blackhawk. You cant go wrong with Michelin quality. -- Review Submitted 2006-02-11

When reading these reviews its often difficult to know the experience level of the author to know how qualified their opinion is. Im a Porsche Club of America (PCA) member of nearly 10 years and I import Euro spec Porsches into the US and have personally owned rare (sometimes first into the US) models such as the 964 RS Clubsport that Ive raced, a 993RS street car, and recently a GT3 Clubsport. Ive got nearly 30 races of experience at tracks like Laguna Seca, Mosport, Road Atlanta, Daytona, and dozens more. I say this only to give you a sense of my experience with high performance driving. Now on to the tires. Ive driven Kuhmo, Hoosier (S03 & S04), Goodyear, and Toyo on the track. Theres no question that the Michelin Pilot Sport Cup is the best DOT rated tire money can buy for track use. I have won at Watkins Glen and Mosport on sunny tracks that turn into downpours and when the other guys pit to change to rain tires, I keep driving with confidence on my Pilot Sports. Ive traded notes with dozens of Porsche drivers and all of us that got burned with Hoosier S04 tires that blistered have permanently changed to MPSCs and theyre unbeatable. Are they a bit more expensive -- not when you consider that for 10% more money you get a tire (unlike Hoosier) that will run 2-3 weekends (thats 20+ sessions) before loosing their grip. The Hoosiers are good for 1 weekend and even on Day 2, you notice the grip going away. Wanna get caught rain in Hoosiers? No way -- not with only 2 rain channels. Theres a reason that Michelin tires are more expensive -- theyre unbeatable in their designed environment. I run the Pilot Sport AVS on my Mercedes E55 and that car will handle like any 911 in the corners with no body roll. These tires are sensitive to air pressure -- run them at 35-36 hot and theyll never let you down. Let them get over 40 pounds and they get slippery -- no different than any other tire (you need to watch air temps). I heartily endorse these ti -- Review Submitted 2005-10-13

I do PCA DEs and club races with these tires. Yes, they need lots of heat to work properly, so you have to drive the heck out of them to get them up to temp. I can get 50 or so heat cycles out of them before they lose grip. I wish they were cheaper (I wish for a lot of things) but theyre a better value than the Hoosiers. Unfortunately, theyre not as sticky as the Hoosiers. In the rain, I use full-tread Toyo RA-1s, so I have only driven these tires a few times in the wet. Standing water is an eye-opening experience but what else would you expect with a tread that looks like this? -- Review Submitted 2005-09-14
