Yep I did some more research and found this out also. Still hesitant on ordering until I find the right fitment for a stock GTR r32

A good shop should do a fitting to see what works best for your vehicle.

Anyone have pics or fitment of 18 9.5 + 22 or +30 on stock front 32 gtst guards?

Very useful. Or measure. As GTSBoy said, 17x9 +30 just about lines up perfect with the outside of the guard.

10.5 +22 is 27mm beyond the guard.

When you say just about lines up at the front, how many mm could I go extra?

18 X 9 + 28, 25?

This was relating to R33/R34. I don't know with regards to R32's. There's probably some difference between R33/R34 and R32 that is known, but not by me :p

[GTSBoy]

R32s have skinny guards that won't swallow as much wheel sticking out from the hub face as the 33s and 34s do. The clearances on the inside are approx the same though.

Yeah, but... how much skinner is it? 5mm? 10mm?

It seems like the later cars will swallow something at least an inch bigger than what will comfortably fit under an R32 guard. It makes sense. The R32 standard wheel width is 6.5", and I think the R34 is 7.5" (and it is isn't, it's 7). They put on a wider wheel to ensure that there wasn't a gaping gap making the car look silly.

Anyone know if this will fit without modifications for a R32 GTR? 

Work S13P

[F] 18x9.5 +24 O-disk
[R] 18x9.5 +24 O-disk

+22 fits very well so +24 should fit as well.

What's O-disk ?

It’s just the brake clearance specs for work wheels. 
 

Disk Type:
・A disk - Standard brake clearance
・O disk - Small brake clearance with deep rim
・L disk - Big caliper brake clearance
・R disk - Big caliper brake clearance
 

I’ve since found out that for R32 GTR you’ll need R-Disk to clear front brakes without spacers and rear can be O, A, or R disk.

How much will they foul by?

Sorry PranK what does that mean! This is the first time I’m buying aftermarket wheels so I’m learning all the new terminology on the go haha

[GTSBoy]

He means, "How much negative clearance is there between the back side of the wheel disc (or spokes) and the outer face of the brake caliper?"

Brake calipers can foul by being too large a diameter for the inside of the barrel, or they can hit the back of the disc area. People often ignore the latter possibility.
