that diff looks horn under there! will the break upgrade be able to retain the stock 13s? or will they now not clear the discs? what did the upgrade set you back if you don't mind me asking?
Cheers! Welcome back to oz? I'm pretty stoked with it I must say. A diff conversion is relatively cheap for the improvements gained. The killer is the centre, yes a reconditioned Borg Warner centre from a SS commodore is an easy option to keep costs down. I went KAAZ 2 way LSD which bumped the price significantly. hit me with a pm for more details
Brakes: oh brakes. You could talk for days on these things as John mentioned above. I gather you mean the rear discs? The fronts are 300mm rotors so nope not on the front, I cant even fit my 15" van steelies on the front! Rears are r31 standard size not sure of diameter at this stage (stud pattern changed to 4x110 of course) so maybe a 14" rim minimum but not sure what fits. I have only had the rims on there but I have a set of 15" E series van front rims to run as stockies on the rear. Everyone has an idea or opinion on brakes. My biggest concern was retaining the original track width front and back. Something not allot of modified mazda owners achieve or care about.
Way way way back when I planned to go a full s2 rx7 disc brake swap as they come standard with 4x110, 13" rims and 4 wheel discs with the fronts vented. So basically if you want a strong diff with small rims then the rx7 rear disc fitted to a diff of your choice would be best bet in my opinion. The other issue is fitting a disc brake and caliper set up under the rear arches without fouling the chassis rails or anything else as they take up allot more space than the old drums. My diff is standard track width, if I was to think of shortening the diff for wide rims the disc caliper would hit the body unless I modify that too. But that opens up a whole lot more heartache!
Well I guess I might as well do an update while I'm here.
Lately its all been about the final assembly. have I got four handle, four door lock pull knobs and dress rings to suit. which leads me into this update: Headlights. So wanting to be motivated and use what little time I get to work on the car I dug out all my remaining parts and laid them out to assess my next steps of what do I need to find vs what I have and is it useable or to a standard where with some work will be ok. One box contained all my headlight globes and retainer rings and all my wagon tail lights I have accumulated trying to get a good pair! No easy task I should add. It seems the wagon taillight was in a vulnerable location and very few lived a life without mishap.
It appears I have quite a few sets of tail lights however most are pretty badly cracked.
I have eight headlights or two full sets, or so I thought!
When I checked them I had eight random brand headlights not one matching set.. it didn't end there.. after that little curve ball I picked myself back up and started to check the stainless retaining rings for the head light globes, yep eight of those but..
5 match and 3 don't! On closer inspection they have a small rib line around the edge as seen here
SSSso then I think well gees at least I have a set of four.. but..
The set of five when turned side on also have a rib around the edge on two but nothing on 3 others.
I look again and the set of 5 so I end up with 3-2-3.
What a pickle! no koito globe set of four and no set of matching trim rings.. Do I offer swapsies to get full sets or just hold out hoping to find the ones needed or put them on and know it is a thing that will bug me but not something you would pick unless you were basically licking the front bumper! gawd.
other than that its just been a case of head down as I try to complete the wiring loom changes in my spare time. Looking forward to the fuel tank as then the car be put on the ground. That will be a tad exciting! cheers!
chasing these rubber gaskets if anyone can shed some info on if they are available anywhere?
Cheers for the PM Mo will get back to you soon
