You need to come out to a NASA HPDE some time!

Remember that the OEM understeer setup is placed in there for safety and driver comfort. Most people are more comfortable with a car that pushed and scrubs off speed on it's won vs one that is loose and has a lot more rotation. It is a learning curve, and one that well all have to do if we change anything fundemental on the car we are use to driving.
But over all a loose car will be quicker once the driver is use to it and can properly rotate it. It will mean that you will have greater slip angles and at each corner exit you will be pointed in the right direction sooner allowing you to apply more throttle sooner.
Just have fun with it and slowly increase the spped back up. And have fun with it. I find a looser car to be more fun after a while. I good friend of mine once said
"I tight car scares the driver and please the passenger, a loose car pleases the driver and scares the passenger".

Bridgestone is already producing the RE-11R as a replacement for the RE-01R,they are supposed to be a big improvement when they are introduced in the US,they've been available in Japan for about a year.

I think I see what you mean Marty. I can see a very experienced driver throw a neutral car into a corner faster than one with understeer. But for me to get to that level will take years. Oh well, this is only my first season and I'm pretty young (23) so I should have a lot of time ahead of me.
As for everybody commenting on the 615's, maybe they're a better autox tire than road course tire? My next tires will probably be R-01R's
There's a lot of really good info in this thread regarding what some ppl are saying about turn in points changing and such that I'll have to read more deeply to understand it all.
And I think Ed's idea of playing on a skidpad is an excellent idea to get an understanding of the vehicle's new dynamics. I've been trying to use autox courses for that, but it's totally killing my road course smoothness. So where am I gonna find a skid pad.........

I wouldn't be so sure it will take you years. It's just a matter that you are driving an almost a brand new car, so it will take some getting use to, especially one that isn't tuned to OEM specifications.
As far as skid pads, a lot of track day groups and HPDE's are now offering optional skidpad time, so I would check with the organizations you tipically register with.

Two observations. 1) don't ever drive them on public roads in the wet. That means wet, moist surface, not even considering rain! 2) don't drive them on public roads (or most other R compounds) in temperatures below 45 F.

the RPF1's are hard to beat for how much they weigh/cost

But I have now gotten into Time Trials, and will go back to a stagered setup, 275/40-17 and 295/40-17 running Kuhmo 710s. I think this will give me that extra traction/comfort when driving at 100% and more overall speed.
Note: I have the Hotchkis TVS kit, that has adjustable sway bars, and SPL F & R Camber arms, but still run stock shocks.

+1: You just need more seat time to get used to your new setup.
I went square AND one size down from what I was running. My car felt VERY different too.
Felt like I lowered the rear end or something. But, I soon discovered I could:
(1) Maintain A LOT more speed into the turn. Less braking.
(2) Didn't need to worry about the front end push as much. More control.
(3) Could start accelerating out much sooner. Less push also meant straighter exits.
I love the setup. However, now that the car is Supercharged, I'm not sure how this stance is going to feel under WOT.
I will see in October...

Front: 295/30/18
Rear: 315/30/18
front aren't really rolled...they rubbed a bit in the beginning during hard cornering - that 'rolled' them enough so that they no longer rub.
still have the JIC-FLT2 coilovers...they're working great - the shocks have no signs of leaking even w/ all of the abuse I've put on them.
**during hard cornering, both front and rear slightly rub on the inside...it's not much, but I can see where the tire makes contact with the interior components.
