This 100% true.
If I'm taking the car over say 4,000-5,000rpm in every gear I'm already 25+ over the limit.
To keep under the limit you have to shift DAMN early.
The bottom line is that most RB powered cars have too much power and revs for our 50km/h streets.
Skylines don't feel fast. Run it to 7,000 - 7,500 rpm and you're due for a 6 month license suspension.
