Any downside to lowering cruise RPM?

[Marc]

Good information thanks...that's exactly what I was looking for.

I am actually coming off the stop before the 60ft (1.6 seconds of stop time and 60ft is 1.9x) so 60ft times are moving more than before, but that's about the only downside I'm seeing. I'll be curious if like the one guy said bad air might cause some consistency issues. So far so good though the car was repeating very well in my first two races.
