It is one bad mutha.....Can't wait for my R.
From another site quoting Kerry Baldori, Chief Functional Engineering, Global Performance Vehicles at Ford:
"We brought our GT350R and our GT350 Track Pack here at Grattan to do fair, back to back same day and same driver comparisons. The GT350R with the Pilot Sport Cup 2 tires is equal to the 100th of a second as fast as the Porsche 911 GT3 and it is over a second quicker than the Z/28.
The base GT350 with Track Pack, which uses the Pilot Super Sport tire, is equal again, to within a 100th of a second to the Porsche Carerra and the Corvette C7 with the Z51 package."
Best video yet IMO
