Been working with Karcepts on a tune for the ND2s for a few months now... Like 99.9% done finally! Celebrated with some fresh 93 octane, my local gas station finally has 93, saves me 10-15 minute trip to get the high octane

Also since you would probably know, are open face helms banned in NJ? My buddy told me they were but I can’t find anything (other than Etown) banning them. I need a new helm and thought an open faced one would be more glasses friendly... and cheaper. |

Openface restriction would be news to me. That's what I use and like that I can talk to people with it on, pick my nose, etc.
The SCCA allows open face, so it would be a NNJR specific requirement.

I installed the AWR motor mounts today. I had Tony from AWR get some "custom" softer inserts for the mounts, 62 durometer instead of their normal 70, 88, or 95 duromater options.
They're a good deal heavier than stock because they're made of steel. They won't break when you launch it or sky it off curbs The install was straight forward. The only real special torque spec you need is the 50 ft-lbs for the cross bolt through the mount. The rest of the hardware just gets torqued to OEM spec (~28 ft-lbs works for the 6 bolts and two nuts) NVH isn't bad. Definitely noticeable vibration at idle and there's a good bit of "tingle" in the pedals at lower RPM cruising (like when the cluster aggressively tells you to upshift to 6th at 30 mph...) and the wheel and seat have a bit of a constant vibration. Highway cruising isn't a noticeable difference from stock. When on the throttle hard or higher in the revs it just feels like the engine is more solidly connected to the car and any vibration is high frequency and not really in your face. Absolutely no new noises or anything like that. I've had a wide range of mounts on my prior cars from literally solid aluminum mounts to soft STI Group N mounts so I feel like I have a decent level of experience with different mounts and these are solidly in the middle of my experiences. Now for how they perform... Damn If you've ever launched an ND at autocross/drag strip/whatever or even on the street you'd know how horrible the wheel hop is. I did diff mount inserts when I installed my OS Giken LSD and it helped a LOT, but man... Holy **** it launches soooo smoothly now! I have never had a car launch like this, just chirp and bit of spin and tracks dead straight. Really fun! On top of the silly launching difference, the way it behaves on throttle transients is massively improved. Less flopping about and it just feels super direct. I love how responsive it feels. I've had the AWR uppers for a while and Tony whipped up a custom one for me to clear my silly header, great customer service |

I remember wheel hop was bad on my srt4, than I change to poly suspension mounts and it was a different car. I always wondered why the factory did not correct it if it was that easy. It nice being able to be aggressive off the line and not worry about a half shaft exploding and filling falling out.
DIdn't realize this was a problem on NDs.

I didn't post a picture of the stock ND mounts but there's heavy usage of plastic, lol. |

Ended up throwing stock motor mounts back in, I was seeing false knock on logs (on top of some real knock as we've been chasing more power)
threw on some new daily driver rubber |

Is there a way around the launch issues without causing false knock?

Nah, sadly not much can be done. There are other mounts (fill the stock mounts with poly, but they can still tear apart...) and they likely don't exhibit the same issue, but no way of knowing yet.
Launching as is isn't too bad, just carries risk of tearing apart the motor mounts if it starts hopping. |

New wheels arrived today Titan 7 T-R8 in 17x9 4x100. Ridiculously light! I'll mount up the autocross tires eventually, but with the season on hold for a while I'm not in a big rush...
