Attention all VIR drivers
No more "dirt" lines...

Until winter when FIA curbs will apparently be added around the entire track.

Never seen anyone get a chipped windshield from the North Paddock, it's all piddly crush stone grit. Now, the South Paddock before they paved was BAD with all out gravel.

Intentionally putting 2 or 4 off over the concrete?
What areas are we really talking about? Coming out of snake? Riding the concrete up the esses? Track out of Oak Tree? Entering hogpen?
Surely, the rut on track out of South Bend is not 'intentional'.

Going to FIA curbs will be a PITA at VIR, totally change the track. Seems the cheaper solution is work on their back fill issues.

I will miss the dirt in 8. A 944 racer I know has taken 8 with his right side tires on the turn 8 curb. I watched him do it in a NASA qualifying session last year.

How exactly is FIA kerbing defined? How is it different from the current VIR kerbing? I only driver over some of the current kerbing at a few spots on track; never intentionally drop a wheel off into the grass or dirt.

Here is what I found:
The profile depends on whether it is an entry, exit or apex kerb and the speed profile for the corner.
FIA kerbs are all 800mm wide.
Apex kerbs rise from 0mm at the track edge to 50mm at 400mm from the track and then stay flat to the rear edge (800mm from the track). These are known as bevelled kerbs.
Exit Kerbs are a bit more complicated to explain but have a 50 to 100mm 'ripple' depending on speed profile. Each ripple is an 800 x 800mm square with a dual grade on the surface on the diagonal to create the ripple against the previous and following 800mm square. The ripple obviously has its tapered rise in the direction of travel. Just to confuse you further this can be a positive kerb (also known as a Vallelunga kerb) i.e. rising from the track surface or a negative kerb (also known as a Melbourne kerb) falling away from the track. Again this is dependant on speed profile. Negative kerbs have only a 25 to 50mm ripple.
Optionally a 2m wide strip of artificial turf to discourage use of the verge behind the kerb is installed at kerbs.
