I got the Z1 installed a couple weeks ago and have the MAM diff cooler, Z1 diff cover, and Motordyne exhaust.

It was a bit tougher working around my diff cooler lines (had a wrench stuck between a bolt and an AN fitting for a good 15 minutes!) but otherwise a super basic install with no interference.

The side that mounts to the frame uses a large machined threaded nut that also sat into an existing hole on the rear brace but no rubber to dampen vibrations.
It's getting into peak winter here in Wisconsin and my neighborhood is all ice, so no driving impressions for a while, much less how it holds up at the track, but so far, so good.

Thanks for the z1 brace feedback. However, did the exhaust make any issues in installing it? and how did you torque the upper bolts (subframe one and the upper diff bolt)

Appreciate your answer.

Regards,

Exhaust was fine, though IDK how Stillen's lines up.

I used a wrench inside the bracing on the nut side and hit my wrench on the bolt side (external side) as hard as I could. Also used blue threadlocker. Not ideal, but best I could do with the space. There's no room to turn a wrench, even a ratcheting one, inside the hollow rear bracing piece.

I would get the Z1 brace before the Bell braces. Think Z1 finally got around to my criticism of the Bell brace. :rofl2:

Appreciated, now it is clear.

Will order the z1 now. Thanks Rusty

Resurrecting this thread…

Has anyone installed the Z1 diff brace with Fast Intentions exhaust? Any clearance issues?

Thanks!

I did, it’s tight but no issues.

@xxAGAVExx You wouldn't happen to have any pictures after the install would you? Was thinking of getting this as well and have the same exhaust.

I took a few pics after install, as you can see it’s close but clears.

You can grind down to the botttom of the "Z1" logo to give even more clearance. I dont think that would cause any weakness issues.

Thanks!

I installed the brace today. My FI exhaust is being shipped this week. Hopefully the install goes well with no clearance issues

I've got Z1 urethane diff bushings already, any point getting Z1 brace as well?

I’ve been curious about this myself. It will make the diff even more sturdy but I worry about NVH. I’m not sure the point going poly mount only to rigid mount on the other end. If they had a way to do it with another bushing somehow then I’d feel better about it.

Maybe just buy this reinforced setup! :bowrofl:
