I've had 122mph out of my mk6 1.6 petrol fiesta zetec. that was when it was about 3 years old and running on 15" alloys. oddly though, when i upgraded to them to 16" i couldnt get beyond about 115. wouldn't try that again now it's 9 years old!

Have something to contribute?

Aye but there are 2 factors to take in.
1. Was the tyre outer circumference diferent with the 15" wheels as this would change the speedo readout?
2. Were they real alloys or just cosmetic alloys?

I'll explain.
A "real" alloy is a lot lighter than the original steel wheel and lessens the overall weight of the car and also improves the handling, due to less unsprung weight.
Cosmetic alloys are usually heavier than steel wheels and add to the overall weight of the car and actually detract fromt he handling.
