I need you guys to point me in the right direction.

I recently lowered my G35x sedan.
Everytime I go over high and long speed bumps, i will scrape the "middle" underbody (the area between the front wheels and rear wheels).

Does anyone know if there is any aftermarket reinforce underbody skidplate available?

Or I need to DIY my own skidplate?

Please help me!

Thanks in advance!
