Yeah exactly. You hear of people never getting caught but then there are horror stories as well. I spent a bit over $2000 on the diff but you get what you pay for. If your spending that kind of money you should be getting a top quality diff.

What crap. RTA has your engineers report on file its accessible to the cops on there computer system. You cant fool them if the bit of paper in ya glove box dont match RTA records ya gone. Therefore carrying around an engineers report means squat if you dont inform the RTA of the changes and give them the details.

perthute, i pulled an sr DET box apart a couple of weeks ago and compared to the RB30 box i also had apart. syncros were bigger, everything else in the front half was the same

RB30 boxes have the higher 5th like the SR DET box also
