Hey mudnut. Did GQ wirh RB30s have a different gearbox ratio???
I used to owne a GQ with a RB30 and up the high country decending in 1st LOW i had to tap the accelerator a lot and not the brake. I'm wondering was this due to different gearing in GU's that youre experiencing. Ironically it was the gearbox letting go on me in toolangi that ended the GQ...
