At the end of the 2016 my car was doing the same as the op. While the wheelies were and are fun, the car would bounce and then vary 2-3 hun in the 60ft. My car at that time had a non adjustable coilovers on the front. I switched to qa1 double adjustables and it fixed both the big wheelies and bouncing issues. All while making the car much more consitant. My car runs 6.30-6.40s with high 1.3 60ft.
