For anyone curious, had the PS4 all seasons installed today on the Arachnids. 265/35/21 front, 295/35/21 rear.
Ride quality is nice, no major difference there - responsiveness is solid and road feel is better (was a high of 40° today). Road noise is definitely present/louder - the A/S comes without the foam inside. BUT, not as bad as I expected - the audible difference isn't much. ARNR doesn't seem as useful with the A/S, but it's not loud enough to be upsetting. Still quieter than my last car that with 18s and 45 sidewalls. (
@planetary - tagging you here to confirm the PS4 A/S do NOT come with the foam of the OEM PS4s).
Speedo is off by maybe 0.5% or less. During testing and with my wife driving next to me a constant 30, mine read 30; at 60, mine read 59, and at 70, mine read 68. Obviously very unscientific testing, but seems okay after about 10 miles of driving.
