Tools needed to remove subframe, along with all the screws and nuts to remove to drop subframe.

Took me longer to disconnect the brake lines and the hand brake cable than it did to remove the rear end

Is it like the RX8 rear subframe , 6 big bolts holding it then all the pissy 10 mm bolts for brake pipe brackets ?
As for the diff , you’ll struggle however there is an Australian company that does -4.7- 5.1-5.4 wheel and pinion
Could be worth asking what they got , they are on e bay

Yep 6 nuts for the subframe, 6 for the suspension and 4 for the brakes I think.

Much easier for me as I have taken  everything else out.

Now I'm wondering whether a get my dad to make solid bushings out of metal OR Use polybushing like I have got for the fronts?

Be nice of anyone's opinions on solid or poly Bush as iv no clue apart from the stock ones are getting replaced.

I understand that full blown race cars would possibly use rose joints/spherical bearings which could be a possibility but I'm all ears.

Found a local sand blaster and powder coater. Might have to strip it all down, make it easier to clean etc.

Going to see what colours they do and go for a light colour, nice to look under a car and see how clean things are and that a person has taken effort to sort a car properly

As for a diff, I have found the 3.9 ring and pinions but was hopeful a stock diff came with a 3.9 but doesn't sound like it

E-Bay -----------------there's just the slight possibility they may be a little sub standard!

I had an Irish rally company send me a 5.1 and a box of bits, I actually got my gear box company to play with it because looked rubbish, they managed to get it set up but expected it to last 5minites
I told them if it broke or wore out immediately it was nothing to do with us as they supplied the thing,   
All the best Clive

A 4.1 diff ratio will work, I will just have to use more rpm.

Need to gets me a diff in next week or so, as want the car back on its wheels as soon as.

However I can put the diff in after the subframe. I shall see

From experience don’t to go taking them mounts of the standard rear subframe
There’s none which will match what you have from standard Mazda ones , only Powerflex and they are shite in comparison
I’m sure Clive  will agree .
Not sure on diffs sorry ,  I do know some one who Run the 5.1 and bought from Australia which was great but only in a standard. RX8

Not quite sure what you mean?

Are you saying the mazda bushings are better or the power flex ones?

The ones in there now have got a fair amount of play and have never been changed that's for sure.

Something iv noticed on the driver side rear wheel arch is that it is covered in grass. Whoever owned the car before me definately took it on track and most likely took to try cutting the grass after the rod exited the block

In bits now

Noticed when undoing the diff mount that the bracket on the subframe flexes a lot?! Worth putting a little brace in there now?

Seems to me it would flex even with everything bolted together. It's not much movement but I can move it with the screw in there.

I'm thinking just some small triangles on either side? Little gusset thingys
