So update time..
i found out the hard way that the BG and BA 4 stud hubs wont bold on perfectly. you will need bg/ba lower ball joints and rack ends but the main prblem is the internal spline on the hub. BF's have a 24 tooth spline drive shaft and BG/BA's have a 26 tooth spline. so my original plan of just converting over to ba hubs has hit a brick wall.
After some days of investigating i found the the 1994-1998 mazda 121 has a 4x100 hub axel with a 24 tooth internal spline. the 1990-1994 does aswell but the hub axel is just a little smaller which wont help my plans later down the track. So i picked up a set of these hubs at my local wreckers for $30 (and the bearings are in great condision too
) and you wouldnt ****ing believe it but they bolt straight on with no mods at all.
HOW GREAT is that.
So i n ow and a set of BA calipers (22v) BF calipers(18v) and 121 calipers (13v) so after fittling around with all different types of setups from wat parts i had i decided to go with the BF hubs and the BA dics i have BUT i will machine them down to 236mm to fit behind the calipers. the reason fr this is because that the 121 hubs have a single solid disc. i wasnt very happe with that so i had a now so old BA slotted disc that i machined down and u wount believe it but the BF calipers are a bolt on fit
how crazy is that..
Anyway so my final front brake setup (for now) is;
- 1996 mazda 121 hubs
- 1985 Mazda 323 Bf capilers
- 1997 mazda Ba disc (machined down)
Ow i also installed my new rear wing, SS front bar, SS rear bar, fixed the exhaust, and fixed my little dent in the rear ...
