The steering wheel now feels a bit stiffer, nothing too dramatic. I like it.
Now the performance results part.
I made the tests with the exact same conditions (temperature / wind), in the same performance track using my RaceChrono telemetry (10Hz GPS).
Weight of the car was exactly the same and I used only 3rd gear to eliminate differences from gear changes.
Speed from-to (km/h) -> Before (secs) / After (secs)
60-130 -> 5.7 / 5.6
60-150 -> 7.5 / 7.3
100-150 -> 4.3 / 4.1
130-150 -> 1.8 / 1.7
As you can see the car is up to 200ms faster in acceleration.
This is a significant change (same effect as reducing 32kgs from the CSL).

Also note the difference in the times... this is the difference between 0 Celcius temperature and 25 Celcius
I am looking forward to test them on the track and see the difference in top speeds
The pulleys definitely improve the performance and in my opinion they cost very little considering the gains !
Highly recommended !
