Parts lady at local dealer says G35 wheels will NOT fit G37 due to size of the rotor/caliper?
My bad for not being clear, I have 19" OEM's, purchased 19" Volks Racing GTAV's in stock width. I understand that my OEM's WILLNOT fit the G37, but, because wheelautohaus ordered me Hi-pass wheels in my GTAV's that they WILL fit if I move up to a G37

 

Yup, correct. 4 piston as opposed to 2 piston's that were in the g35.

 

yeah it will fit.. cusae the OEM G35 wheel's offset is not that aggressive..

 

The G37S wheel specs are:
Front: 19 X 8-1/2 Aluminum/43 mm
Rear: 19 X 9 Aluminum/45 mm

The G35S wheel specs are:
Front: 18 X 7-1/2 Aluminum/45 mm
Rear: 18 X 8-1/2 Aluminum/50 mm

G35S wheels will NOT fit over Stop Tech ST-40 4 pot calipers. Therefore I'm pretty sure they will not clear the G37S 4 pot calipers.

The spoke profile is the key to fitting over BBK's or you can cheat by using spacers.

 

I thought he was talking about the Rays 19"... cause I wouldn't go from 19" OEM to 18" OEM

 

My bad ... the OP wrote G37, not G37S.

Both G37 and G35S have 18" wheels.

As far as I know, G37 does not use the 14" rotor and 4 pot calipers.

 

the G37 non sport pkg cars use 13.0" front and rear from the g35 sedan sport package brakes

 

well my G37S 6mt come with 14" rotors F&R and 19" wheels.

 

They're 14" front, 13.8" rear on ALL G37s's.

Non Sport has 13" all the way around.

 

I think the G37 uses 2 piston calipers, and the Sport versions have 4 piston (up front)

 

I am working with a company to develop a 6 piston caliper that will work with the stocks as well. it should be more narrow to accommodate some g35 owners converting to the G37. ill get more info.

 

is not just the caliper clearance is also due to the offset of the G37 has to run a higher offset then the older coupe..
