Follow-Up Review: 2,000 miles on tires
December 01, 2014
I have done two track days on these tires, plus at l0-15 times street driving on curvy roads, commuting to and from the track, etc. I still really like these as a streetable race tire, but the rears (like most Porsche rear tires) don't last long. With a pretty aggressive track set-up (3 degrees negative camber in the rear) on the insides of the tires I am nearly at cords after about 2000 miles. The front tires have a lot of life left, so I am ordering new rears and they should wear out about the time the fronts do. <br>At my last day at Thunderhill 5 mile I was having trouble with corner-entry oversteer and was power-sliding out of every corner (including 80 MPH+!). I was thinking this was caused by my rears having been heat-cycled more than my front tires, but unfortunately it turns out it is because my LSD is toast. This is a common problem with GT3s, and with no diff it may have caused the rears to wear that much faster. I will update again once I get a new LSD and rear tires. Still love the tire, but if they wear this quick I may be switching to Micheline Pilot Super Sports that last a LOT longer and cost less, without too much sacrifice in outright performance.
Initial Review: 1,000 miles on tires

I bought these Conti race tires for the first time to replace the Micheline PS2s on my 2011 GT3. My typical street able track tire has been RA1s or R888s from Toyo, but I was looking for something quieter. Long story, but I wound up cording my PS2s at the track and being forced to get R888s, so I have a perfect day 1 comparison of R888 vs these Contis. R888s grip well but have massive tread squirm under braking and cornering that makes it feel like the car is going to oversteer. Very disconcerting! They also sound line a helicopter on the highway.
Day 1 on the Contis and, amazingly NO tread squirm. The car felt terrific in turn in, mid-corner, on exit, and under braking. I broke 2 min for the first time at Thunderhill. They sound like a normal street tire on the highway (maybe a touch louder) and ride better than R888s. I even ran into some rain on the way home and they gripped great and evacuated the water fine(although there was no standing water). So after 1 day on the track I cannot say enough good stuff about them.
On the back roads they are also perfect. They are so grippy, yet tail out slides are easy to do.
Overall best street able track tire I have had!
