Ok, very interested in these but in college so 100% broke.

Subscribing for when I get a job in the summer!

This is basically a 1" bump from 11" to 12", plus the much bigger calipers. Would be a phenomenal upgrade to factory brakes without the hassle of fitting WJ knuckles and steering

That is exactly why I looked into doing this. The rotor is 1" bigger diameter and also thicher and heavier and when coupled to the bigger dual piston calipers, makes a big difference, braking and heat resistance. And it all fits in 15" wheels.

I had a bunch of extra pieces left over, I always buy to get free shipping when possible and to have extras in case I break something.

Nothing wrong with the WJ conversion. You get proper tie bar and raised drag link steering and heavier knuckles. It is just more work and costs more.
