Hey Jam
Just saw your now selling you RS's and losing $500 on them..............Man if you have already ordered a 2.8L stroker etc dont turn back. I have x2 GT3582r high mounts with smaller rear ex/housings + ext. gates (+ plus bigger cams / no head work), Im sure these will come on bit later than your Rs's, but hey when they come on its all over. Yeh its a different drive than the snappy 2530's and need to keep Revs up a little more, but hey thats the whole idea of having 4wd!..
so i guess your Rs's are only gonna spool up quicker compared to mine.....Aim for 400kw my friend and stick to what you have
