Superpro UCA bushings - personal experience
I bought the car (see description) at 120k miles with bad front upper control arm (UCA) bushings . For some reason I decided NOT to spend 200$ and change the whole UCAs but to spend ~400$ (maybe more, I don't remember) and have the Superpro ones installed. What I got is:
1: an angry mechanic (actually a friend who couldn't understand why I did that) because pressing them on the arms was a huge PITA - that was immediately
2: nasty camber ONLY ON THE LEFT that ruined a tire (the bushings turned - they are "camber adjustable") - that was after about one year and 10.000 miles
3: worn bushings (on both sides, worse on the right) after less than 3 years and 30.000 miles - this is when I started hearing clunks, it might have happened earlier.
They might be good and give you a (marginally in my opinion) better steering feel but I don't think they are worth outside the track
I hope this helps!
P.S. Those 30.000 miles had less than 1% of hard cornering and/or bad roads (potholes) and during this time, nothing else in the suspension failed (including even some original parts - like all the bushings on the rear suspension)
^ they are not worth it at all on the track because they don't stay locked in position and you loose the camber too easily with the craptastic setup they have
