Who has a big brake kit? Post your OEM 20" Wheel fitment and spacer size if you used one!

Some I gathered searching, some don't 100% make sense but I think people just used a spacer that works, possibly not the smallest possible evident by the actual clearance needed.

Fronts:
Rotora 6 Piston 10 mm spacer
Rotora 8 Piston 15 mm spacer
AP Racing 4 Piston 15 mm spacer
Stoptech 4 Piston 10 mm spacer

Rears:
All kits seem to clear OEM wheels

Clearance needed:
AP 4 Piston 1.52" clearance
Stoptech 4 Piston 1.7" clearance
Rotora 6 Piston 1.8" clearance
Brembo Gran Turismo 4 Piston 1.88976378" clearance
K Sport 8 Piston 1.37795276" clearance

Obviously:

Infiniti 4-piston Akebono Fronts: 15mm.
Clearance needed: 38mm = 1.5" (Calculated. Stock 06 clearance was 23mm + 15mm spacers)
 
What about wheel size?
I remember a long time ago someone mentioning that a minimum of 19" is needed for ROTORA 8-piston 380mm disk front. Is that true?

Or can a stock 18" wheel be fitted with a 15mm spacer?

If anyone knows, please, advise.
 
you can get the template to measure your required spacing from rotora or other BBK manufacture.

the size (diameter) is important but also the wheel design (spoke).

(I didnt know they made a FX in 02 ?!)
