Nismo SSR Comp 17x9.5 +35 Square Track Setup w/ pix!
Did some additional testing since I borrowed some 3mm shims that may be useful for others, and me when I forget.
This is for front wheels only on OEM studs, hubs, suspension (i.e. no camber plates), OEM Spec camber, Brembo, with 17x9.5 35ET SSR Comps. Also this does not take into account fender clearance/rubbing but I have some notes on this below.
No Shims= 255/40/17 fit, but only about 2-3mm clearance of both wheel and tire from suspension. A little too close for comfort IMO. Plenty of brake and fender clearance, wheels are tucked.
+3mm = Comfortable, but not large, clearance with suspension. Scott was running Hoosier 275s which run wide from what I understand.
+6mm (two shims)= begin to run into issues with number of turns on the lugs, only getting about 5-6. Typically recommendation is 7-8 minimum although most say 8 for the stud size/thread pitch. Tires are tucked a little, but not too much. 5mm shim should be about the max spacer to use with OEM bolts and is supported here:

+9mm (three shims)= OEM studs unusable, can't really get the lugs on without a struggle. 255/40 are looking pretty flush and clearance may starting depending on negative camber and tire size. Might want to talk to people with ~+25ET and see what tire sizes are clearing without rolling the fenders. Scott mentioned the 275 width tires won't clear the fenders with +10mm but this was for 17x9.5 Enkei RPF1s.
In addition, the SSR Comps won't clear the OEM studs with the convenient gaps between stud holes. You would have to grind or put on shorter studs. Math and caliper measurement backs this up. OEM studs measure about .95in (24mm) from the rotor face to tip of stud, depth of SSR gap about .3in (7mm), so 24 - 9 - 7 = 8mm. This doesn't take into account the width of the wheel however.
+15mm spacer could go either way. Based on math from above (24 - 15 - 7 = 2mm) it wouldn't clear, but there is some width from the wheel and some slop/rounding that may negate that final 2mm. Let's just say it will be close. I might buy some +15mm for the back wheels and test them on the front to see if they clear.
+20mm, no problem but then you have to start considering tire width and fender clearance. Should be nice and flush though with approximate +15 offset (35 - 20 = 15)

If you decide on anything larger than the 5mm shim-spacers and don't want the spacers with their own studs on them (I don't like those for heavy tracking, though others have used them without issue), I suggest the ARP extended studs: http://www.splparts.com/main4/index.htm
I don't like that you can't (easily) re-torque the lugs on the spacers that have the built-in studs after each track session. Sure you can easily re-torque the wheel to the spacer, but there's no easy way to ensure the lugs on the spacers are staying tight without removing a wheel. It only takes one of these to completely ruin your weekend:
I bought the gorilla open lugs to go along with those ARP studs (12mm x 1.5 pitch):
All of your Shut your FACES!!!
The issue is not the size of the wheels!! 17inch wheels are better for tracking your car then 19inchs are. YES the NISMO comes with 19inch in the rear and 18inch up front.
All he needs to do is fix his tire size, because right now they are to short and also his speedo is off big time!! with that setup.

I would just do a 275/40 front and rear , then for spacers 10mm up front (slip on style) with good studs, for the rear, just pick 10 or 15mm (slip on) will be fine and will also work great with your stock street wheels.
