If you get a 4.0 from here on out, you'll have a culm GPA of 3.67 by the end of your first semester Senior year. It's quite a feat but if you attain that, you'll have a good selection of solid colleges to target. However even with that, top tier selective colleges are not viable.
You should expend more energy on your classes than your ECs. If it's the difference btn having 0 ECs + a 3.67 GPA or a ton of ECs + a 3.0 GPA, you should ALWAYS do the former. 85% of colleges (and all the colleges you'll likely target) will GIVE NO ADVANTAGE to you based on your ECs. It's a myth
