Correct...they were the old 'old' model.

The Star-Specs come up to temp more quickly than the 'old' type...grip is same.

If you go to Nationals, and have a chance at placing, why wouldn't you run the tires that you can make some money on?
If you are going to Nationals and know that 'you have a chance', more than likely you're going to put on the best that you can--contingency or not. Alot of testing, particularly by Andy Hollis, was done to show that the B-stones are several 1/10th faster on a 60second course. The $$$ is just gravey.

I'm still anxious to see what the new Kumho does.
As am I. I'll jump ship if they are faster...

WD40 I'm only going by what I've seen at events around this state.
And as I mentioned, the Dunlops have had a horrible showing from what I've seen.
Maybe it's the temps (we have a lot of 90°+ event days), maybe it's the cars (a couple STIs ran them, a Vette, don't remember what else),
or maybe it's the drivers pushing them too hard?
Most of us that want to do well, are spraying our tires after each run at those (heat) events.
I'm definitely aware of the heat issues with the RT-615.

As far as Nationals, I only give the tire companies 1/2 credit for who wins what class.
Bridgestone has had a contingency package for quite a while.
Falken (IIRC) has never had one.

Course, with all that said...
Unless Falken comes out with a new tire, I'll be on something different once this set is wore out.
I do believe competition improves the bread, and as each company is coming out with a new tire they're getting better and better.
Falken set the benchmark a while ago with the RT-215, but it's since been surpassed by several tires now.

I'm still anxious to see what the new Kumho does.

Unshaved Z1s just won a NT on a heavy STU car...would bet they are faster. They are on close out and have a rebate, so they are likely cheaper than the Falkens.

So we have (likely) faster and (likely) cheaper...and awsome rain performance for the street.

...um, boy, I dunno what to say.
