Low Downforce For DarlingtonThis weekend at Darlington Raceway, NASCAR Sprint Cup Series teams will be running a low downforce aero package similar to the one used earlier this season at Kentucky Speedway.
The spoilers on cars will br 3-1/2 inches talll instead of the usual 3 inches tall for Darlington. Also, the spliyter will feature a 1/4 inch leading edge. The tires this weekend, which will have a 1970's look to them to honor The Tradition Returns weekend this weekend, were specifically made for the low downforce package.
The Kentucky aero package had a splitter extension panel of 25 inches. That will not be tge case in this Darlington aero package. It will be the normal length in this aero package.
Tire Talk For Darlington
"We had a very minimal change in grip at Kentucky from what we raced there in 2014," Greg Stucker, Director of Race Tire Sales for Goodyear, told SiriusXM NASCAR on Wednesday. "Just a little bit more grip on the left-side tire, and the results of that particular event I think were very, very positive. "I think the low-downforce package showed a lot of potential. I think a lot of people walked out of there thinking that was a really nice package. It certainly reduced grip, put a lot of control back into the drivers' hands. Did a lot of things that I think people were looking for."
Stucker said a "considerable amount of grip" has been added to the Darlington tires, with hopefully will offset some of the aerodynamic grip lost with the aero changes on the cars.
"The reduction in downforce going from the standard 2015 (package) to the low-downforce package increased lap times by about three-quarters of a second, 7/10ths to 8/10ths, something like that," he said. "That much slower. When we put the grippier setup on, it gave us about that same 7/10ths to 8/10ths back."
