Nitto 555RIi Drag Radials are available in your stock size for the rear and will do the job very well. You can run the Pirelli’s on the front, or if you want to match up the tread pattern and look you can get Nitto 555G2’s for the front.
Why wouldn't I want 555Rii all around? NVM.
But Nitto says the G2 won't fit the front? 255/40/R19?

Because you don’t need drag radials in the front. They are to give you traction where you need it.

they should. Check the OD number. that is what you need to match. The G2s would be a great front tire, but not sticky enough for the years if you are 700+HP at the crank.

I'd do the half shafts, but that's me. Read the "S550 Weakest Link" thread recently posted
Had a good call with the tech this morning. My driving habits are mostly spirited driving. Since I am not drag racing the car with any frequency and very few "hard launches", he recommended not doing the half shafts at this stage. Said he's seen many 800+rwhp on stock half shafts with no problems. If a half shaft happens breaks, it is not a major issue and easy to fix.

Definitely doing the solid aluminum driveshaft.

Looks like we're going with Kooks headers; apparently Stainless Works LT headers are 12-18 week back order.

They fit the front...

Nitto 555G2 on the front 255/40/19
Nitto 555RII on the rear 275/40/19

If you want to save a few dollars leave the stock Pirelli tires on the front
Yup that's a nice plus that the g2s match up with the r2s.

Currently I run
Nitto 555G2 on the front 285/35/20
Nitto 555RII on the rear 315/35/20.
