Memo from John Darby to teams Friday morning.....

Open test @ CMS March 23-24 covering wing to spoiler transition.
 
I still don't think the rear wing caused Newman's car to flip, but I think this is a good thing because it shows NASCAR is listening to their fans and teams.

I imagine that the new Cup cars will be something like the new Nationwide cars: splitter on the front, spoiler on the rear.

I thought I was the only one that felt this way. I'm glad to know that there's another one out there.

I heard an interview with an engineer yesterday afternoon about this spoiler. It was said that because of the height of the COT, this spoiler will be much larger than the ones of the past.
 
But see, now, the NCOT and CCOT will be the same, so that differential between the 2 cars that NASCAR wanted, is going to be gone in all except the nose.

I read that sentence 5 times and I have no idea what you're talking about.

I think he means that he thought that NASCAR wanted cars from the Nationwide series to be different than those of the Cup series. The Fords and Dodges will be different because of the pony cars, but Toyotas and Chevys will use the same car in both series, albeit different wheelbase and other slight differences.

I don't know if I'd call 160+ more horsepower in the Cup cars a "slight" difference.

Okay, there's a big difference. But it's no secret that the Cuppers began driving in the lower series to gain information for their Cup race. It's gone beyond that, but they still get good data from their Nationwide cars. Now if they really wanted the cars to be different, all they would have to do is put Hoosier tires for the Nationwide cars. That would make them completely different
 
While they are going to have the open test to all teams @ Charlotte on May 23-24, next week in Texas, Tony Stewart, Kurt Busch, Greg Biffle and Brian Vickers will be getting a 'jump' on the competition. Goodyear is conducting a tire test and also will be testing a new four-inch spoiler set to replace the rear wing later this season.

I'm sorry, but if they're doing testing because they're making drastic changes to the car, EVERY team and driver should be invited. Like you said, the guys that are invited get a jump. Even if they have to share notes, you'd be naive if you didn't think they were getting an advantage.

Don't worry, Andy. I just called the track to see if I can get credentials.
 
This time I have to agree with Andy. Anytime a team gets track time to test it gives them a advantage. Like tire testing. They gain a jump on those not involved by learning what works and what doesn't.
Other teams have to learn in a few hours of practice what the testing teams learned in a 1 or sometimes 2 full days of a test session.

Na$car should spend some of their money, build a few test cars, and hire Dave Marcis, Ricky Rudd types as test drivers for these tests.

Then publish the results so all teams get the same info.

"Level playing field and parity", right Na$car?

I never thought of it like that. Brett, Geoff, Rickey, Dave, Ward, Terry..I bet they'd love to be able to run, even if they weren't in competition.

Thursday afternoon will be the formal announcement.

Specifications for the new spoiler and quarterpanels on Sprint Cup cars were sent in a memo Monday to teams by series director John Darby. According to the memo the spoiler that will replace the current wing will sit 4 inches atop the deck lid when measured from the centerline. The spoiler will be level across the top with a ground clearance of 43.52 inches from the top of the spoiler to the ground with the chassis on 6- and 8-inch blocks. The spoiler will be 64½-inches wide and one piece from right to left. It will be fabricated from 3/16-inch thick aluminum and fixed at 70 degrees. The fuel filler hole must be relocated forward of the left lower tip of the spoiler. Also, right and left quarterpanel extensions will be added to all cars. The extensions will be 4 inches long toward the ground at the rear wheel opening. The modifications, according to the memo, are not to be used in competition until all wind tunnel and on-track tests are completed. An open test [at Charlotte] is scheduled for all teams in March. The changes are being made in hopes of improving downforce and improving the quality of racing. They are not expected to be used for the Daytona 500 that kicks off the season on Feb. 14. The Bristol race in March is a more likely target.

Fixed at 70 degrees, nascar should really give them an adjustment of plus or minus 5 degrees.

hmm, shouldn't this have been done before mandating the changes? seems a bit bass ackwards.
 
Do I read it right that the spoiler will be 4 inches tall? Wasn't the one on the "old" car 6? Of course over time it was trimmed on some makes for 'parity'.
 
From the spoiler, err ah, tire test @ Texas.....

NASCAR Sprint Cup Series drivers Tony Stewart, Kurt Busch, Greg Biffle and Brian Vickers became the first drivers to conduct an on-track test with a new aluminum spoiler package that could be implemented for the 2010 season during Tuesday’s Goodyear Tire test at Texas Motor Speedway.

“It (the spoiler) was on a bunch. It didn’t seem to be a big balance change which was good,” Stewart said. “That means you won’t have to invent the wheel necessarily. It was a balance shift, but it wasn’t a big balance shift. You’ve got two kinds of grip – you’ve got aero grip and you’ve got mechanical grip. The spoiler is the aero grip and the tires are mechanical. The mechanical grip is real important because it doesn’t know if you are running first in line or 10th in line. I’m more of a mechanical guy.”

“I thought it (spoiler) was good,” Vickers said. “I thought it added a little bit of front downforce, which is a good thing. I think it’s going to be more accepted to the fans. It looks cooler – a little more retro back to the older car.

“We haven’t been in a lot of traffic yet, so the big question is how it’s going to handle in traffic. Theoretically, from what I’ve been told, the difference between the two is that the spoiler is better in traffic. The spoiler is going to be more efficient in dirty air and a wing will be more efficient in clean air. Once you get in a lot of turbulence, the spoiler’s not going to lose a lot of efficiency while a wing really will.”

Here's a better picture of the new spoiler with the lower side skirts on the back end of the car (red part):

The "stamped" spoiler doesn't do much for me. Maybe it's from the different color tone, it just looks different from the old spoiler.

Looks like it's non adjustable and it extends out over the quarter unlike the old one.
Haven't a clue what the quarter ext will add??

Yes, it is nonadjustable according to what I keep hearing on NASCAR Radio. They say that the quarter panel extension will cause less air to flow under the car should it get slideways which they hope will help keep the car from taking flight.
