Mine took a little work but ultimately fit fine with the performance pack pan. Decided to give it a more oem look by using nice two piece clips vs the nuts and bolts they provide for the installation
I installed them with my bmr set up, i will say they are a massive pain in the ass so if you have any ambition to do it you should do it while you have everything taken apart. They are replacement bushings for the lca, not a new lca. So you will have to press out the old and press in the new.
