There are way more upgrades to list but just looking at his sponsors sticker-ed all over the car, he has AirRex Digital Suspension, Seibon Carbon Fiber all over the car, performance wheels, etc.
The “Air Force” GT-R (R35) was the first Liberty Walk (LB Performance) wide body Nissan GT-R in the United States. Paul is an active duty Air Force member who loves his JDM and along with his many sponsors and the personal assistance of Wataru Kato (President of Liberty Walk) built one of the coolest LB Works GT-R outside of Japan. The car is a multiple show winner and was proudly on display near the entrance to SEMA. Steve hasn’t seen Paul in almost a year, and has yet to see the car finished. It was a great opportunity to convince his friend to let Steve take the wheel of the car for a little test drive!!
It appears AirRex Digital Suspension was added after AutoCon.
