Hmmm....I have to say I don't agree with you.
Mods like lifts, oversized tires, or brake kits are items that CAN be done as a mod (because you are installing parts to REPLACE existing parts, not add to them). It would be a different story if you tried modifying a brake outside its designated design (as is the case with raising the back seat so the locking pin/latch sits higher.)
