Default Dunlop Direzza Z1 Tires 'Star' in SCCA National ProSolo

Quote:
AKRON, Ohio, April 3, 2008 /PRNewswire/ -- Dunlop's new Direzza Sport
Z1 "Star Spec" tires came through with "flying colors" at California's El
Toro airfield.

Racer Richard Jung, of Laguna Niguel, Calif., won the Street Touring
Ultra (STU) class with the new street tires on his Mitsubishi Evo in the
2008 Tire Rack ProSolo opener at the former U.S. Marine air station. Then
he did what he believed was unthinkable.

The vice president for CiroDesign, an Irvine product-and-graphics
design company, raced against 32 drivers from all classes in the Super
Challenge "format" and won all five elimination rounds. He was crowned
Super Challenge champion. Jung was the only SCCA driver using Dunlop
Direzza Sport Z1 "Star Spec" ultra high-performance tires at that event.

Jung said, "El Toro was a great debut for the new 'Zed One Star Specs.'
The class win created a lot of interest in Dunlop tires. I did well
previously on the Direzza Sport Z1 tires with an STU class victory in San
Diego two weeks prior, but the 'Star Specs' were even better.

"I can feel the difference; you can push 'Star Specs' on the first run.
This was an advantage, since it allowed a more consistent feel and reduced
the need for suspension adjustments between runs," Jung said.

Matthew Neidert, brand manager for Dunlop high-performance tires, said
Jung's class win "proved the Star Specs could be a top contender in STU.
But by winning the Super Challenge in one day, he kicked down the door. His
times and consistency allowed him to take the win over the cars from other
classes, even those with race-compound tires."

A win in the hotly contested STU class is noteworthy, Neidert said, but
Jung's overall win in Super Challenge "truly is amazing. He really had his
Evo 'dialed in' for the competition."

Jung said he became interested in Direzza Sport Z1 'Star Spec' tires
when he read press reports. "I didn't really plan to be different, but to
be a top competitor in the class, I feel it's important to test tires to
find out what works to gain a performance advantage. We're still learning
the tire's characteristics, but so far we've had pretty good results," he
said.

The new Direzza Sport Z1 "Star Spec" is available now, qualifying it
for use in Sports Car Club of America (SCCA) national events. According to
section 13.3 of the 2008 SCCA SOLO rules, tires must be readily available
by April 30 to qualify.

The new tire features the "Star Spec" tread compound, which helps a
performance car's initial dry grip during sanctioned amateur driving
events, such as autocross and high-performance track-events hosted by
regional car clubs.

A high-response directional tread pattern with circumferential grooves
helps create a consistent contact patch on the pavement for a smooth feel
and seamless transition. An "optimal mold shape" helps provide a consistent
footprint shape and uniform pressure distribution across the footprint for
enhanced cornering, Neidert said.

Dunlop is a global tire brand with an excellent reputation among
performance car enthusiasts. Well known for its prestigious
original-equipment fitments and sports car racing heritage, Dunlop is also
a key supplier to sport compact enthusiasts featuring "tuner" tire sizes
and race series sponsorships. For more information on Dunlop's performance
tires, go to http://www.dunloptires.com.

Matthew Neidert worked at Goodyear as an intern when I interned in the Racing Tire division. Kind of you typical engineer, but hes in more press releases than I am, haha.

Dunlop is partially owned by Goodyear, for the record.

Interesting news, mostly because I've been planning on getting a set of those tires to replace my beat up RT615s.

Lots of marketing propoganda in there. From all accounts though, R. Jung had a well deserved win at the event!

That's what I read about the older Dunlops models but from what I've been seeing on these, they're not the same...maybe they've learned???

TR didn't show availability for the 235/40/17's I got but I Luke had a couple sets and I got in on them. http://forums.nasioc.com/forums/show...1469992&page=3
