Broken pitch stop firewall mount...

Not to thread jack (too much since this is driveline-related at least), but I did the same install over the weekend with the same results. Noticeably louder. I'm going to give it a few hundred miles, though, before I make a final judgment. Between these mods and the Whiteline rear diff inserts the driveline lash is at least 50% improved. Well worth it for the relatively low price of the mods

I should have added in my original post, a big part of the reason why I did the trans mount was to reduce the load on the PSM. I currently have a Torque Solutions unit in place without the pitch stop brace (which is on my list of things to do). I just wanted to reduce all the drivetrain lash I could to help "save" the PSM brackets. |

I was very pleased with the rear diff inserts. Noticeable improvement in back end tightness with only the slightest marginal NVH. However with the transmission mount and bushing install, I am also at the "edge of my comfort zone". I am considering swapping the Perrin mount with the Group N mount in order to turn down the NVH a notch or 2 to get in my comfort zone, but with folks complaining about Group N, maybe it is not worth the swap. Does anyone have experience comparing Perrin with Group N trans mounts regarding NVH? |

I didn't notice a huge difference in vibration, but the Perrin gives your shifter a more mechanical feel, while the Group N feels a bit "smoother". |

Forgot to share this. In perrin's example of the cracked pitchstop bracket, my car was the one with the forged beatrush PS. I also installed a beatrush transmission mount along with the PS. The cause of my crack was due to missing driver side motor mount bolts.
The engined moved so much that when I went to finally get my bracket replace. while removing the dash & PS, the found that my beatrush PS actually bent from the excessive engine movement. Big Ron's body shop get me all setup and the car feels great now. |

Holy ****.
Out of nothing more than my curiosity, how would you describe your driving habits with the car? I've never seen anything fail that hard. |

At first I thought I had somehow screwed up when installing my kartboy SSK & bushings, but I started to notice a lot of side to side play when I would accelerate in 1st and/or 2nd gear. I kept grinding 3rd gear when I was switching gears mid corner while at BW and it was really screwing with me. At first I thought It was a cracked transmission mount since the stock one was so soft. In this video I put a go pro underneath the car and drove around. You can see the whole transmission move left to right when I get on it. Last clip showed the side to side movement. At that time I swapped the TM & PS for the beatrush parts and it seems to had fix my problem temporary until I went to buttonwillow again & again kept grinding gears when switching from 2nd to 3rd mid corner. To stop it from happening, I had to just shift much slower where I felt the transmission settle and I slipped it into 3rd. Super annoying. It was only till I was on the forums did I seee people cracking their PS bracket that I checked mine and saw it was cracked... took it easy on the car till i brought it to adan at AQ motorsports and he told me I had missing motor mount bolts when I wanted to swap the motor mounts for beatrush mounts. |

One lesson we can learn from this is to check your engine mounts and make sure the bolts are still there.

I remember way back in this thread someone getting their bracket replaced, had to have their dash removed as well as the transmission to weld on the new bracket, which must have been a nightmare! The TSB doesn't show you having to do that. It also looks like a procedure a Mid-Level DIYer could accomplish if they wanted to. |

I would suspect that any power or other drivetrain mods will be a reason for non-coverage given the potential for excess strain on the mount over stock. I've got a perrin PSM brace sitting on my workbench that I'll still be installing soon regardless of this 2 year extension. |

Same thing goes with the TOB...mine has been making noise on cold mornings since 500 miles, so I have gotten used to it at this point. I would rather live with the noise that goes away in a few minutes instead of letting the dealer drop my trans and risk more issues as a result. Kind of jealous of anyone with a VIN after the cutoff for those two items that are getting the beefier pitch stop mount and redesigned TOB |

that TSB makes me sad that it wasn't out sooner..... But they probably would have blamed it on my stiffer PS and not on my missing motor mount bolts

As it says it's an extension of the vehicle's original warranty on that item specifically, I would think that it's out the window with mods. However, if mine breaks, I'll try to have the dealer cover it even though I'm modded.
