[QUOTE=Jim@tirerack,Jun 19 2009, 11:00 AM] I still don't have the test results but we should have them soon.
I liked the RE-11 the best overall in driving them.

 

sooooo many people have made this mistake and have made driving their cars very unsafe (IMO) with running 225's in other brands. If you not running OEM you MUST run 245's in the rear people, plain and simple.
I personally run 255 out back.

 

The only problem is that the last time I checked, they don't make star specs in a 245/x/16 size. I could be wrong though.

 

Another Direzza Sport Z1 Star Spec. stock cr size on an AP2: Aaron is right, squish city. This is a great street tire. I find it quiet and a lot less bump thump than the 050. I also find that it has worse turn-in (granted it is a much wider tire up front). It is very predictable, with smooth and predictable breakaway, but just sliidddeesss. It has higher grip than the 050, but not as crisp feeling overall.

It is a mediocre track tire and I'm not happy at all for it in dual-purpose mode. I have some R-615s and they are much better for turn-in, sliding grip and even overheating (I had an opportunity to go back to back at Thill with them). I should have gotten the XS.

 

Anybody going to compare the Nitto NT05 with these? I already have the tire, just want to see the review compared to these tires.

 

WRONG.

225/50-16 is perfectly fine in back, and if you are running 245/45-16s you are definitely NOT running the best-gripping street tires available.

FORGET the stickie. There is MUCH more to grip and safety than a simple tread width dimension.

Die stickie die! I know it was well-intended, but now it's just driving people away from the best tires available, for no good reason.

Tire make/model is WAY more important for grip/safety than either the size designation or necessarily-arbitrarily-measured "tread width" number.

Star Specs in stock AP1 sizes are going to give more wet grip than any street tire available in 245/45-16. Or 255/45-16.

Speaking of which, who makes a 255/45-16 anyway?

 

How do the Star specs compare with the Falken Azenis 615?

 

Star Specs blow them out of the water imho.

 

On my 240sx with Koni 8611 dampers and 8k/6k ERS 245/17 all around, my Direzza * Specs pull an average of 1.1g on the street measured with a Racelogic Performancebox. That was with -3 degrees of camber up front and -1.7 in the rear, zero toe.

You'll need the Performancebox software to view the data.

I would agree that the Direzzas blow the Azenis out of the water. Azenis are overrated, a lot. People just can't seem to let them die and accept that much better street tires are available.

 

And i thought the 615's were insane.
