I got a std Ed hatch and I’m going to need either dx,ex, or si front knuckles for my b swap. I was just wondering if theirs any difference in the front knuckles since they are all different level trims. Like is the ex knuckles better than the dx because it’s a better trim let me know thanks.

yea the ex ones are a little beefier and have bigger brakes.
dx/lx/std are all the same iirc.
