You don't.
Spinning your rocket during ascent has no effect on its stability, and in fact only makes it harder to control because the controls will be spinning along. Meaning if you try to tilt your rocket in one direction, you have to account for the spin, and good luck with that.
Also, a solid fuel second stage? Solid rocket boosters cannot be throttled down or shut down once ignited, and provide excellent thrust to weight ratio but poor efficiency, which makes them useful when trying to lift a heavy first stage, not when you need to control a spacecraft that's about to get into orbit.
