Would you mind sharing thoughts and maybe pictures of this? I bought them, but haven't gotten around to installing them yet. Thanks.

The installation is pretty straightforward. I've removed and installed dog bones multiple times. Won't really be able to comment on what they do until I finally get car out and have it aligned.

Thanks. Understood. I look forward to hearing about it.

Brackets and rotors are on. Brackets are just a bit tricky since the bolt holes for the trailing arms are spread a bit further apart. That makes for some additional work in lining things up to bolt back together.
It's best to bolt the bottom arm first, then top. Keep things loose until all nuts are on, then torque down. Other possible sequence is to connect bracket onto trailing arms loosely, then bolt bracket onto chassis. This will draw both arms towards chassis rail without needing to line up arms with bolt holes in bracket.
I did not do that preferring to torque bracket bolts first then install arms.
Rotors went on easily. Well made. Dimensions seem spot on.

Front Fascia delivered to BNC Auto Body. It'll be stripped and re-sprayed. Should be back in 2-3 weeks.

Tires have been mounted and balanced. DAMN they are wide. I hope to have
pics next weekend with weather getting warmer. Thinking of pulling plenum and do a quick rebuild on the starter while I'm at it. The thing is, you never know what else you'll find in the "while I'm here" zone.

I installed my DRM brackets today. Took about 1 hour to do both sides. Be careful to not drop the nut in the back into the hold where the screw goes. I dropped two of them on the driver side.

I just unbolted the dog bones from the trailing bracket and then the bracket from the frame. With the dog bones still attached to the knuckle the trailing arm brackets slide out from the bottom.

Very easy. Now I need an alignment.

Had discussion w Pete on possibly massaging the cylinder heads some more, but our concensus was that motor feels pretty strong right now. Bang for the buck not as strong as maybe looking in other areas. With updating my Invos to
Mich SS, I started looking into the whole rotational mass thing. Seems that this is an area that would yield better results in terms of ROI. The Michelins will add a total of 10lbs over current tires. Also, the Z06 brakes are large w front rotors weighing in at 28lbs. ea./rears 20lbs. ea.
Been researching the alternative rotors and have found two that look up to the task. The preferred rotors by the Z06 crowd is the Coleman 2pc. rotors built by Performance AFX. These rotors weigh 17F/15R. They basically reduce rotating mass by 30lbs overall w 20lbs coming off the front end. Rule of thumb is 1lb ~1hp. On the dyno that should mean about an 8-10hp pickup since the front wheels aren't going anywhere.
However, the mitigating factor is that the new rear tires will be ADDING a total of 6lbs. The rear weight loss will net out at 4lbs. The net weight loss on the front after new tires will be 16lbs for an overall net weight reduction of 20lbs.
Pickup of 20hp to the wheels would be huge. Other benefits are quicker steering and shorter braking distances.

Rear Rotors(pic) are made to accommodate the Z06 eBrake. Side view is of front rotor.

Sorry if this has been asked before but do the C6 ZO6 breaks and rotors bolt directly onto the C4? Less the need for larger wheels if using the 14" rotors?

Thanks.

Karl,

The C6Z brakes use an adapter similar to the C5 brake adapter. However, it's not the same because the Z06 caliper is pushed further away from the center of the hub using 14" rotors. And u do need minimum 18" wheels with good front clearance.
Whenever I remove those "dog-bone" bolts, I always snap on a small vice grip onto the nut so it doesn't fall into the frame. Sounds like u were able to recover them. You could also duct tape the hole.

which nuts are you referring to falling in the frame?
