pending advise

I'm just seeing you're 7A/T as well...I still have factory 3.357 diff w/Quaife helical locker & would break them loose also,,,but not like the 3.69 gearing.
4.92:1 1st gear & 2nd gear nearly as low as a stick car's 1st......fun to drive.

I'd say for a bit of drag and street go with the PS4. All out drag the R888 will put the power down hard on dry just not good on the rain. For track use the Pilot Cup 2 tires are beastly and perhaps the best you can buy for track use only. Downside the tire will wear out quickly and they are really expensive.

Everything I've read...especially with respect to the track...gives a slight edge to the PS4s. If you don't plan on switching tires/wheels for track and street, definitely the PS4s.

R888s

...for drag. These put it down hard but will float on humidity.

Enjoy;
As my 314whp would blister up some 345/30/19 Invo's (if not warmed up for drag),
20,25,30mph roll...would really run the tach w/cold tires.
I have PSS's,,,but never got chance to run them.
RIP:2011 370z 7A/T w/3.69:1 Diff. & only a tick of negative camber.
Looking forward to next build!
You will likely light up anything you try below a certain temp/speed.
