Front diff mount ripping car apart


ZT-R

Recommended Posts

This style... pretty much where it bolts to the car. I probably need to go in and line the area with 3/16 plate and make my own but i made a subwoofer box out of my tool storage area so i don't have access to that area. 

i'll get some pictures the next time i have it on the rack.

this isn't mine. I am thinking about doing some like that with the upper brace. mine is cracking the sheet metal where i drew the lines. i put the little 2x2 inside and welded that. it also ripped out the front most bolt treads, not sure how I'm gonna address that yet as you can't get to it.

That's for the short nose R200 or R230.  Not a great design.  The nose of the diff is lifting on a short lever arm, with the mounting bolts in to the frame as fulcrums (fulcra).  It's been critiqued (criticized?) before.

 

Make a better title, with the diff style in it, and a description and you might get some recommendations.

Looks like the mount you're using is the TTT mount.  Surprising that they sell that.  https://technotoytuning.com/nissan/260z/complete-r200-r230-rear-end-conversion-z-car

 

Arizona Z Car has (had?) another mount style.  It had some minor issues,  Word was that they were working on another design.  Might be worth a call.  Or you could fab up something similar.  It puts the diff nose load perpendicular to pieces that can handle it.

 

He used to have pictures on his site but they're gone now.  Maybe working on a patent or something.  Or maybe they have problems.  Who knows.

 

Here's where the pictures used to be - http://www.arizonazcar.com/lowarms.html

Just noticed that your picture in #5 has the center brace up to the body.  That changes everything.  I think that other stuff is in the way though, so not as simple as it seems.

I don't really know how that site works.  It did tell me that the Whitehead link was saved one time on January 28, 2013.  Probably by me in a Hybridz thread.

 

Arizonazcar was saved 107 times and none of the old snapshots show the diff mount.  

 

It was referenced in the other thread so the picture was there at that time.  Not sure the Wayback snapshot shows the old data or the new.
