The GB didnt fail, people's perception of PAR failed after hearing lots of bad things about PAR gearboxes letting go. What wasnt mentioned though, is that they were all SR20 boxes, so after a wave of unhappy SR owners PM'd me and made the thread look shitty, i closed it cause i CBF'd with anyones bullshit when all the time the GB was meant to help people
...not a single person came forward with a GTR box that had a problem. There's a reason the RB box into the S chassis is so popular. There's even a few traders selling the kit as a complete bolt on option on NS.com
So yeah, im going PAR, there's also another low profile but massive HP GTR up here thats about to aswel. Come to think of it, there's a very high HP and profile GTR being rebuilt now and using a PAR box (oil pump let go on motor).
Anyway, to each their own
