Yep, plus the speeds are different.
Naturally these are sprint day speeds NOT happy laps speeds.
I normally enter the main straight at 100kmh and enter turn 1 at 140, the exit of turn 2/start of the back straight is also at 140-145kmh, the entry into turn 3 is about 80kmh and during a race you're breaking as late as possible. As you can see you have the potential to be going a lot faster at the end of the back straight than the front and the corner at the back is much tighter and slower.
