Looking good, hope it works well for you.

My understanding is that the roll centre alters the drive characteristics such as, understeer by lowering the rear and alternatively if raised it will tail around and oversteer.
Similar to sway bars.
Don't know if it will alter straight line traction, I think that has more to do with spring and shocker placement and in your case the geometry of the caltracs.

Got it installed a couple weeks ago.  Traction is a lot better on dry pavement and slightly better on wet.  Hopefully that will translate to more consistency, better 60 foots and lower et's.



I made a holder to use with my transmission jack.  This is a prototype, proof of concept   I'm sure I can make it better and it will probably work better with a normal, typical shop floor jack.



Also installed a drain plug, applied some epoxy to hide my gnarly weld and ensure that it is leak free.  So far it is leak free.

Nice work Charlie! Did you MIG weld the drain plug port in the rear housing? If so, it had to be tough to do.

Yeah, mig weld.  I think I'm pretty decent when I can work out in the open, with good lighting and plenty of room.  But upside down, with poor lighting and with sparks falling on me and limited space available for positioning, that makes it a little more challenging - I still need lots of practice with that.

If I had known how thick the housing is in that area, I probably would have simply drilled and tapped, but I do like that this plug is flush with the housing and it has more threads than the housing alone will allow.

Hope you did a quick gear clearance check on that drain plug install.  Would hate for you to get a noise you couldn't figure out.  LOL.  Just a caution.  Joe-JDC

It is well below the height of the mounting flange so there is plenty of clearance.

Charlie, 
        when you make the Pumpkin holder for the jack, make two. I'll take one, that's neat.
