The front and rear sub-frames are ABSOLUTELY tied to the main structure. There are two large pilots that come down from the monocoque to locate the rear sub-frame along with 4 bolts. The front sub-frame is located by two pins and six bolts. If the pilots and pins and bolts don't hold the sub-frames in place... never mind. People will believe what they want to believe regardless of the facts.

Again..just like when we build a race car and we replace all of the rubber with spherical bearings to keep them in place the same has to be done for the engine mounts, diff mounts, and in the case of the Camaro...the rear subframe. However when dealing with street cars not everyone wants to completely remove a nice "quiet" ride from their car so the braces make a nice option to keep it from shifting around while giving the rubber isolation to the main unibody. Sorry....I think it of it more as a unibody than a monocoque...that would be McLaren F1, LaFerrari, 918..... |

I agree with you on the solid sub-frame bushings, but still view the additional bracing as a toaster cover. Toaster covers are effective and functional but the function they provide is not necessary. The changes that were made in the rear sub-frame bushing in the 2012 model year were a tremendous improvement over the first two years. The 1LE, ZL1 and Z/28 sub-frame bushings are clear improvements over the 2012 SS bushings. For most 5th Gen owners with models 2012 on up, the benefits of solid sub-frame bushings are available but not necessary. For those that drive to the limits of the vehicle, solid sub-frame bushings are both necessary and functional. Last edited by JusticePete; 11-21-2015 at 09:19 PM. |

Thanks for bringing the tech fellas it is quite educational. Since the topic was primarly about subframe connectors and not the addition of bushings. So I take it the Bushings make a far greater difference to rear chassis then the sfc's. So LG have you guys tested with just bushings and then with the SFC's, did you see an improvement of any kind, besides additional weight and profit off of a client.
I had a street car that I ran Delrin bushings and Sperical bearings it was precision, but I bet I could tell the date on a dime when I drove over it. Car was tolerable for short trips, anything longer and it is not fun. |

FYI -- Changing out the sub-frame bushings from OE to solid aluminum will increase cabin noise, especially tire song, but will not alter ride quality in a negative way. |

JusticePete, I must say your ride (from post#12) looks HOT!

Thank you. If you liked the red one, maybe you'll like the yellow one.
Or this soon to be completed white one. Last edited by JusticePete; 11-23-2015 at 10:43 AM. |

We have done our fair share of race cars as well and even a few Championships with Camaro....

When we do the track cars or race cars they have solid bushings and sleaves in them, no braces as the rear subframe can not move with solid sleeves in place....just like what you would find in a C5/6/7 Corvette as they have bolt in subframes as well (technically suspension cradles). The only downside to running a solid bushing in the rear cradle is more interior noise. If that isn't an issue then yes you can solve the problem with less weight. |

These are what our clients consider street cars.
Or this soon to be completed white one. And not a one of them has a sub-frame brace. |
