Funny I found this post from George Bark back in 2014:
"Heres some advice when using Vega MBS's on pavement....
Flathead Racing, RS & LR should be cut.
Animal & Clone Racing, Uncut tires, but LR should be cut.
2014 MBS tires somewhat need internal prep from testing this year.
1-3oz in the rights depending on air temp & 2oz in the LF. If its over 95 deg out, I don't see using any internal prep.
The 2014 tire takes a few extra laps to come in, and require more heat to generate better lap times.
The MBS Yellow vega was replaced this week by the MCS...…."
