Hankook Ventus RS3 *Merged*

I'm going to try the RS-3's next year for street duty/autocross (10-15 events) next year.
I've been on
Street tires:
AD07's (never autoxed, just DD'd)
Star specs (really liked these for a street/autox tire)
NT05's (didn't like as much as the Dunlops for the street/autox)
Not for the street:
A032R's (sucked ***** for autox)
Hankook's Z214 (INSANE grip obviously, even for just the c51 compound). A local guy who's consistently ran A6's, tried a set of the C51 Z214's and he even thought they were slightly faster than the A6's. This coming from a past National Champ that's been in the game for 10+ years. The prices on these are pretty competitive too, unless you step up to the c71/c91 compounds which are more on par with A6's.
I can't wait to try these out. Most likely I'll be going with a 255/40/17 unless I step up to an 18" setup next year.

This is great discussion guys. Thank you very much! I've been waiting a long time to hear from someone who actually uses the RS3's. Now, having said that, just because Nitto NT01's are advertised as a DOT approved competition radial, it doesn't automatically make it better than another brand's extreme summer. Companies can advertise whatever they want, it still comes down to performance and lap times. I think we should respect people's opinions and comments, especially when they have been tested on track by a driver who have used both brand of tires.
I had a feeling the RS3's would not be that great in the wet. Kinda like the Kumho's. And the limited sizing really does suck. Dying to see some Tire Rack charts. Those tests and charts are awesome to stare at when researching tires.

I am not sponsored by Hankook, I wish I was, and I have the receipts for the tires I purchased if anyone really wants to check. The tires have proven faster than NT01's repeatedly. Attached is GPS lateral acceleration data from Autoclub Speedway this November at Redline Time Attack's final. This is the record lap set on Hankook RS3 255/40 17 tires. Note the 1.71 G peak was set in the banking, but over 1.4! G was reached in the infield which has no banking. Granted the Professional Awesome Evo is very well prepared, but the tires contribute quite a bit.

Playing devils advocate here, what data was used and how is lateral acceleration calculated? If you used GPS, what was the sample rate and how many points did you use to smooth? If there was a hardware accelerometer, how was it calibrated? Was that on concrete or asphalt?
No doubt the car is very well prepared. In hundreds of hours of logging virtually every top street tire (dunlop, bridgestone, hankook, yoko, falken, toyo, kuhmo, I've never seen consistent 1.4s on a flat surface. I do have a few logs with numbers that high, but it's always some kind fluke in a transient state -- the car on bump, bouncing, etc.
Sorry to go slightly offtopic.
cheers,

Our car corners extremely well and we beat the previous record by a full second with approx 250 less wheel horsepower on a track with over a half mile straight. We pride ourselves on being able to turn well!

This has turned into a real good thread 
Probably pick a set up for myself soon for the new season. They are $500 a set and if they are indeed close to NT01's thats a steal in my book. Anything has to be better than NT05's in the rain too...those are just downright scary.

According to Wikipedia the surface of Auto Club Speedway is asphalt. It was calculated with GPS using an AIM Sport MXL Pista dash. I cannot tell you the sample rate or how many points unfortunately, but as I am sure you know the AIM Sport MXL is commonly used in all forms of motorsports. I do have data with the built in accelerometer, but I do not have that handy at the moment, I can post it later.
My experience with several GPS loggers (maxq, trakmate, aim, etc.) is that the peak g values tend to be a little suspect. Compared to real accelerometer, they have a very hard time catching quick or violent events. It's bitten me quite hard when testing tires.
I do agree that the RS3 is an awesome tire. There's a set mounted on my race car right now.
However, my testing has not shown them to be as fast as the next tier, which is the harder compound race tires (NT01, RA1, R888).While I'm thinking about it...Like many high performance tires, I found a significant increase in grip after one very, very good heat cycle. The RE01R/RE11 is the same way. This is in contrast to the Z1 which was _fast_ by the 3rd lap. As always YMMV.

Gotcha. How cold are we talking about. I know all the extreme summer category turn into bowling ***** when it is near freezing. It snowed in Seattle in Novemeber and I was still rolling Z1's..........that was quite the experience. Are we talking that cold? Or did you mean tires were cold and the weather was also cold and they didn't work too well. Curious with that spin out you had....
