as for the spacing in the front between the radiator and the front of engine/ ancillaries, it does seem real tight at only 15mm dude, the engine/body combo will move that much when ya punt into something. have ya been able to offset the deeper part of the fans with voids between the ancillaries etc? that could be quite beneficial..
was able to do that with mine although this pic ya cant quite see the amount of room gained, ya can sorta see the idea i'm tryin to get across, even if my engrish is a rittle rough..
