^^^Yeah, even the R2 cars have a modern (and therefore a bit more 'tame') anti-lag system on them.
But since McKenna is using an 'old school' Focus WRC 2.0 liter power train, it has a bit more
pronounced 'bang-bang' system on it!
One thing I noticed from working the starts is that the Vermont Sportscar, Scoobie Rally Team USA cars make a
much louder 'clang/ring' when they engage first gear at the start of their countdown to launch than any of the other sequential equipped cars do.
The R5 cars are using a 6 speed Sadev box, as are the Scoobies, albeit an obviously different configuration due to the drive train layout differences.
(McKenna might still be using the X-Trac sequential which was standard on the S2000 Fiestas, I will have to ask them at STPR.)
I wonder why that is.
