I highly recommend the do-it-now-so-you-can-enjoy-the-benefits-for-years things:
Amsoil for all fluids, of course.
Very good ceramic coating applied to body, brake calipers, wheels
As many different brands of wheel locks as you do not regard as overkill. I use 3 different on each wheel. (3 sets of different brands)
K and N or other brand you like high-flow air filter
Super magnets (preferably flat bar type magnetized north-south through the skinny, flat side) to put on and reuse on your oil filter(s) (KJ Magnetics is the brand I found)
Super magnet drain and fill plugs for your engine, oil cooler, transmission, and rear axle
You will have no regrets from any of these things at all.
I run pure propylene glycol coolant and no pressure (rad caps just sit loosely on the tanks,) but you are on warranty, so you may prefer to leave water and pressurized rad caps on your system.
