I am on my third set of Kumho ECSTA MX's and I think they are as good on dry as the GY and two plus times better in the rain. It is my daily driver. The blocky ouside half of a GY F1 does not have a rain channel worth mentioning. Therefore the outside half is hydroplaning on rain soaked roads. Kumho's are cheaper and have a symmetric tread pattern and handle cornering loads just fine. I would only consider another tire if I was only going to roadrace or dragrace then I would do other tire brands and types otherwise Kumho :thumb:Subw00er said:For those guys going with the Bridgestone S-02... This is the OEM tire for my other ride, a Honda S2000. Expect very fast tire wear - most s2000 owners only see 8-10K miles on the rear if they dont drive like woossies. The front will typically last to 15K. I'd imagine a z06 owner will see less than that. However, the s-02 is the ONLY tire I'll put on my s2000 due to very little sidewal flex and great grip. It is a very directional tire and very communicative (road feel is great). One thing I dont like in the handling department on the s-02 is the lack of warning before it breaks free. There is basically 0 indication, so you have to be careful. They also suck in the rain after 1/2 worn.
The s-03 is a less grippy tire but will last a little longer and have more indication of eminent traction loss. It is also much better in the rain. (BTW, dont go with RE750's, they are very sloppy and not a real performance tire, I dont care what the specs say! They're terrible - I've actually returned a set to tirerack I was so displeased)
I think I'll look at a cheaper tire for the Z06 because I dont think the stockers are particular spectacular for the price, although they are definitely a decent tire. The Kuhmo MX looks promising..
I put 34k miles on my original F1s and still have a few thousand left. Very impressed with the life of these high performace tires. My driving isnt too spirited but I do work them on corners sometimes (never drop the clutch at red lights). Never drive in rain and if it suddenly starts to rain when im out, I am in the right lane. Not too impressed with the dry performace, traction breaks a little early on hard corners, high speed runs could be a little more tight and ever since I added the basic mods (intake/full exhaust/tune) traction breaks around peak horsepower RPMs in 1st and 2nd gears. Like I said, I NEVER drop the clutch, but even rolling off the line and giving WOT up to redline it almost always breaks (summertime driving, when the street is hot). Dont need a wet/dry tire, just a max dry performace tire. What do you guys think about the BFG G-Force T/A KD or Michelin Pilot Sport Cup?
I just bought those recently and could not agree more. I like them and the fact I only paid $935 installed was nice too.I am very happy with my Kuhmo MX's. They are much better in the rain than the SC's and gave very good feed back at the limit in the dry. Great all around tire.
