If your wheels are too hot to touch then you probably have a brake
problem (or you are riding them/failing to downshift for long
descents). Removing the wheel covers could help with brake cooling,
but the effect on engine cooling would be negligible.
Hondas have excellent engine cooling. The only time I have ever had a
gauge go much above half was when the system had lost coolant. That
has happened two or three times in 35 vehicle years of ownership of
five Honda cars. I have run these cars in Chicago traffic in ambient
temperatures from -28F to 106F and I have never found the cooling
system to be inadequate in any way.
So I would suggest that if yours is inadequate, it may need repair or
it may be due to one or more of your modifications. If the former,
then fix the problem. If the latter, then feel free to make whatever
further modifications are necessary to correct these problems. Just
don't whine that the car is defective.
