I just replaced my stock suspension with coils at 85k miles and the only thing I 'refreshed' was new heavy duty upper strut mounts, and the only reason I got those was because I knew I was going to remove the old suspension with an impact gun, and because I didnt want to bother compressing the old springs and removing the old mounts.
The kit you posted is cool and all but realistically you wont need to change most of that stuff out until 120k+ mi.
Depending on the coil over kit you get you may need to reuse or purchase new bump stops.
Depending on how low you want to go, you may need new, adjustable endlinks.
I wouldn’t buy that unless one of the control arms already on the car is damaged.
Definitely replace the upper strut mounts and throw a new bearing in there and absolutely replace the rear position control arm bushing. Also have a really close look at the tie rod ends and ball joints, but if if the boots aren’t cracked or leaking grease and they feel tight there’s no reason to replace them.
^ that with fresh struts will really transform the car, but if you want to take it one step further the rear trailing arm bushings go to crap about as fast as the front (rear position) control arm bushings. Poly bushings for that spot aren’t expensive and because there’s no rotational friction against the bushing (inner metal sleeve) there’s no extra noise.
