@TalonTsi90 did an expert job fitting the tow hook based lic. pl. relocate kit... witness the minimal annular gap around the shank... and his step drill use was brilliant to make a clean cut edge (in fact I asked him a bunch of questions about how he did this) ✔✔.
Visually, the relocate kit is an improvement... and it either obviates the need to drill holes in the bumper cover, or allows existing holes to be neatly hidden with suitable small plugs.
Having said all of the above, I personally would not do a plate relocate that uses the tow hook port because in the event of a front end accident you will not benefit from a more distributed degree of collision force loadings being introduced onto the unibody chassis that the stock arrangement affords you... {i.e. allowing the
whole width of the bumper cover and the
whole width of the bumper reinforcement bar (immediately behind the front bumper cover) to absorb said force}. That is, as opposed to a more point loading, highly biased to one side of the car.
One comment though: at the
back bumper area of the Mazda6, the
bosses for the tow hooks are located on the actual bumper reinforcing bar... which is good... because said bumper reinf bar has engineered-to-crush columns. Likely this is the same in front. Trouble is that with the plate relocate arrangement, the collision load is introduced almost exclusively on one side of the car. Inevitably more damage to the car ensues... and it might be sufficient to result in a "total loss" versus a repairable accident. Actually, some folks might prefer a "Total Loss"...
