    so after 1500 miles here is what I found my trip to town is 27 miles 2 of which are off road
    usually I use the ODO reading for mileage which shows the" from start" mpg,
    at each end of the journey it would show 62/64 mpg which would turn out to be 60/61 actual mpg this was at a CC of 45MPH as its a very quiet highway there was no risk to other users I used CC to remove a variable from the figures ,after fitting the discs my ODO readings would show 67/69 mpg and this turned out to be an actual MPG of 64/65mpg in fill ups so not a huge increase as mentioned by other user here but interesting ,I stopped the test due to much colder weather now and also I lost a disc in an off road traffic accident avoidance maneuver, I am going to try this test again @55 mph when I get a replacement disc .

    It mataid aerodynamics, but it is also compromising brake cooling...like on a long downhill stretch.

    I don't have any steep downhills on my trip and I use regen to slow down so no brake problems
