Diff Plates Flexing MX5 based saturn chassis.

[andysredmini]

Has anyone beefed up the diff plates (cp26)?
I have just tacked mine on and they can be flexed by hand.
I know this will reduce when fully welded but im considering replacing them with 5mm and cutting down d12 to suit.
Should I bother or leave them as they are?
Will it have a knock on affect on anything else?

Cheers

Aren't they supposed to be 5mm anyway? I'm pretty sure that's what Spud told me to use when I did mine.

i used 3mm, thats what spud's guide said. was a bit in the same boat about the flex, but reckon it will be ok. if not ill strengthen them up!

u use 5mm john?

Hi,
Should be an easy fix if you are worried about it. I will have a look tomorrow on my chassis and if it is a problem I wil probably press up a "U" profile joining both diff mounting points and also bolt down to diff plates around the diff mount.
I made mine from 3mm steel as per the drawings and my chassis is painted so wouldn't like cutting and welding parts to it now.

Thanks for the replies. It definitely says 3mm in the guide, page 2 i think.

Did you use 5mm then skov? if so, no problems further along in the build?
(i know its only 2mm but you never know).

I think I used 6mm! Might be a tad heavy, but it certainly doesn't flex

[andysredmini]

That should help as a retro fit.
Im going to make some 5 or 6mm plates at work tomorrow.
I can do some extras if anyone wants some.

Here is the back end I'm building.

ive not hauled my diff out yet, but is there any pics of them, would it be possible to weld in some 25*3mm flat in line with the inboard ends of the diff mounting plates, meaning that the diff mounting holes would be 3mm recessed, but would add the required rigidity?

just an idea....

Here's some pics of my 1.6 diff if it helps Stew:
