Installation Notes and Tips

Verify rotor condition, caliper operation, and pad fitment before installation. These pads are for front position use only and must be matched to the exact Lexus model, year, and package notes listed in the fitment data. Confirm whether your vehicle is an F Sport or non-F Sport application where noted, since several RC, GS, and GS hybrid listings exclude the F Sport package.
