One thing to add:
It isn't unheard of for a quality 3-way racing damper to be a second or two faster than a lower-tier double or single adjustable damper. It also wouldn't be surprising for a quality 2-way (double adjustable) damper like KW to be a second or two faster than an off-the-shelf cheapie asian coilover, let alone a few seconds or more faster than stock. You won't see these kinds of gains from stock suspension with non compliance bushings.
A quality double-adjustable damper is a HUGE tuning tool that affects the response, transitions, balance, compliance, grip, and more of the car. Non compliance bushings reduce bushing deflection. Due to the travel of the stock suspension and its soft spring rates, it's possible that the reduction of roll from a coilover would reduce the amount of bumpsteer and toe change more than eliminating the deflection from the bushing alone.
I believe its a clear winner between replacing those bushings and the KWs in terms of improving the car's performance, predictability, tuneability, comfort, etc..
I will state and caution that some no-name coilovers with no motorsports or racing history (often from Asia), can actually make the car handle and perform much worse than stock. INVEST in your car and don't cheap out on suspension or tires.
