Staggered may be 'common' but pointless.
Run 19x9.5 or 19x10 squared with 275+ (can go 255-285) meats of KNOWN GOOD quality tires.
If you want Cadilac ride, go buy a Caddy.
20" tires are becoming much more common but the tradeoff tends to be stiffer carcass (except Continental) so ride quality...
PP (non-MR) dampers are a joke. Don't waste your money.
Buy Bilstein B6 or Ford Performance 'track' shocks. These are damped correctly.
It is unclear if/any improvement Ford made with the mag-ride for S650. In S550 the dampers are sad and benefit massively by replacing them with the SKU used...
it's only a matter of "cool". It gets old quick. And it's just leads to failure because Ford engineers are morons and didn't armor the control cables. So they get cut, short, and blow a fuse.
If your exhaust is "droning" under load you're in 1 (or more) gear too high and lugging the engine...
bah humbug on the "screens". :)
If you want an Eco HP, you really should consider this one.

the interior is identical. So your statement makes no sense.
But sure after DRIVING both I can see one's opinion changing. Especially when you realize the EB doesn't come with the correct transmission.
my 'FP by B' system (S550) included the resonator. I didn't install it since I went with Steeda H-pipe. The sound level is very nice and not obnoxious and blatty like most exhausts.
