one of the things about venting the third radiator upwards is that the act of changing the orientation of the third radiator interferes with the rad ducts on either side. so, to do it properly, one of the tricks is to change over to gt2 rad ducts (or, I presume, gt3 units). of course, that means a bumper cover change as well. i presume the wheel well liners can be swapped without all that, however. i think jfros approach with the third rad was to block the bottom vent and let the air travel down then up to the centre vent on the top?
