dude, everything has trade offs. Those lower control arms probably transmit a bit more road noise into the car right? But they hook up better. Thats the compromise.
the aftermarket shifter is much more sturdy, prevents you from damaging the shift forks, has a much more direct feel, shortens the throws, and makes it easier to shift from 2nd to 3rd quickly without missing gears. The trade off is a bit of noise. id say its worth it.
it ain't a lexus, its gonna make some noise aftermarket shifter or not. Better yet, add an exhaust to the car and you won't notice the shifter noise.
