Yep Zed stuff is 9" [228.6mm] so not a straight swap of the drum - it will have to be a complete backing plate/drum sway = might as well go to discs, well that is what I am planning to do on my B210

Quote:Theoreticly, if you had a single disc brake at the back of the trans, then it would be part of the sprung mass, but to be effective, you would need a spool because with a regular diff, you could lock up the driveshaft with the brake, then have one wheel in the mud at the side of the road with the other on the good stuff & find one wheel rolling forward, while the one on the slippery stuff is actually rotating backwards.
The net effect is no rear brakes at all. The spool would prevent this, but it increases tyre wear & makes it hard to park in shopping malls.

locked diffs are fun in carparks! i almost got arrested for driving my subaru with a sticky rear diff that tended to chirp in tight turns.

yeah i see what you mean, there would need to be a LSD, so if i had a lsd though it would work, because having a lsd is a desirable thing. but if i'm going to get a phantom grip i might as well get a 200sx rear axle and disk brakes.

there aren't going to be any 280zx struts or 200sx rear axles left for their proper cars ;)
