offset on the Track pack Z front and rear wheels
 

does anyone know what the offset is for the OE Ray Track pack Wheels front and rear? is the front 30mm and the rear 33mm. coz i put 25mm spacers on the rear and still i need a little more to flush with the fender. but does that mean 33mm-25mm=8mm offset for my rear? i'm confused, please help me out!
