I'm pretty sure my car must have been an early-year production of the MY08. I checked my hardlines before I bought/installed the MBC/booster and they were the correct size, 10mm. My car also didn't have the stretchbelt that is supposedly part of this model year as well, I had the tensioner so I didn't need all the Gates parts from Grimmspeed.

I from cars101, the cutover was in roughly July 07. Know what your build date was?
EDIT: I went and checked my MBC, 12mm. at the booster and the ABS controller. Damn.

I just put my STI master cylinder/booster in tonight after having it sit on the shelf for over a year. Everything went in without a hitch in my MY08.
Wait. Don't 08's have VDC? Did you have to reflair or change the ends the hard lines going to to the ABS brick on the other side of the car? What year were your STi parts?

You can turn of the VDC in the 08 as well; it is just a button.
The cars equipped with VDC have a different size flare nut (12mm vs 10mm on non-vdc cars) on the end of the hard lines that run across the engine bay from the master cylinder to the ABS controller/pump. You can either change the nut and re-flare the lines or build an 10mm to 12mm adapter. I Not sure if the hard lines are the same inner diameter on both or not or if the volume change would matter that much.
Reflaring is not something you want to get wrong as that would lead to loss of braking ability. But any adapter you build will need flare nuts as well. I believe they are bubble flares but I'm not 100% sure.
VDC was standard starting in 2007 on the Spec.B then in 2008 it was standard on Spec.B, 2.5i Limited Autos, GT Autos, and 3.0R after July 2007. It was an option on Manual 2.5i Limited and GTs but I'm not sure if that stared in 2007 or 2008. The easiest way to check is to see what size the flare nuts are on the master cylinder. 12mm = you are engineering something. 10mm = direct swap; afternoon job with the correct parts.
