The front and rear wheel fairing 120mm deep lowered the total drag by 0.071. This corresponds to a 17.15% reduction in total drag. (#7, pg. 11)
Edit: the 0.104 reduction was from the best configuration of mods, per page 12

Goro Tamai found that the wheel-related drag on their solar racer could be reduced by 80%.They did a test rig as did Cranfield,and then verifies by on road empirical tests.
There's some fruit to pick here,but as members have mentioned,we've got to be careful of the context in which the data is acquired/presented.
