SAT II's

I’m a high school senior looking at highly competitive universities, but I don’t know if I should submit my SAT subject tests to these colleges. While my scores on these tests aren’t bad, I’m afraid that they would take away from other parts of my application (I have a 33 composite score). As for the subject tests:
Chemistry=710
U.S. History=670
Math II=660
Should I just forgo submitting these scores to the colleges I’m applying to as they’re only “recommended”?
