np guys, glad that you've found it useful.
bitz: they are different platforms in that the parts are not interchangeable, ie: DBA rotors or hawk hps pads for the GT are not direct fitment for the 2.5i
but in terms of dimensions and hardware a full GT brake swap is most definitely possible and has been performed by members on this board, particularly N.sane, i know of for sure has done it, link to his post re: swap
but reading over the FAQ i can see how it was confusing the way i worded it, i changed it to clarify that. hopefully makes more sense now.
hm i didn't think about the front underbraces but you bring up a good point, i've never really looked into bracing just because i figure most people wouldn't really bother with them on a DD but in the rear it should bolt up the same... i guess i'll have to investigate that a little more. or maybe someone else can chip in regarding this?
edit: i just reviewed N.sane's info that he sent me re: 2.5i suspension and he does mention that the front underbracing will not fit; also edited the FAQ to reflect that info (thanks bitz for bringing that to my attention)
