Does anyone know what the offset is for the optional GT 17" x8" cast aluminum, bright machined, split 5 spoke wheel is? I want to upgrade to a 19" wheel, but I need a stock baseline from which to calculate a new offset.

 

45mm

 

Are you sure fairlane292? I thought the offset was 24mm.....maybe you're right, I'm not super sure, but when shopping for wheels for my '05, I found the offset at 24mm(I bought some A R Razors-since sold them as new '06GT has polished 18" Bullitts-which I really like). Just my experience......

 

Stock IS 45mm. Unfortunately the Razors only come in 12 and 24mm offset, about 35mm would've been perfect.

 

Fordracing.com if you don't believe me (or look on the back of the rim). many aftermarket rims have inadequate offset and thus tires get pushed outward in the wheelwell; not a look I am fond of but that's just me, prefer correct offset to get rim/tire inward.
