Dr30 > Z31 Compatability

[datto_boy]

Just wondering if the 5 stud Z31 bits will fit on a DR30 as in the front discs and so forth..

If so what needs to be done?

I see you're from Adelaide any pic's of your DR?? and is it on the road at the moment?

....Sorry no idea if those parts will fit though

Why play with 5 stud when 4 stud Z31 bits do the same???

Front disc rotors are identical to DR30, calipers should be as well, rear discs are SUPPOSED to be the same but DBA replacements have a lower hat height, but that really isn't a problem, just need a 5mm spacer washer and longer bolts.

Anything else ???????

I know for a fact the rear calipers off a Z31 bolt straight onto a R30 disc rear. Have just had to do it myself.

On a side note, the pistons were actually bigger than my standard HR30 ones.

Thanks for that!

Bummer that my girlfriends Z31 got taken by the insurance company yesterday!

Does anyone else know a rear caliper up grade? Does not have to use the same set up for hand brake (i will be using hydralic) i know vb-vs or something go on the rear of a 31 anyone know if this is the same for the 30's?

so you used the better ventilated z31 discs? alot is similar, the struts would be. but the caliper bolt spacing is not the nice 100mm for 4 pot conversions and the like.

if swapping anything make sure its a jdm one. not a aussie one.

No I was sorta on a budget when I did it, the only reason I replaced them was because my right hand caliper had seized and I couldn't find any R30 with disc rears, as the majority of them were drum except the hatch's.

When I save up a bit more cash I will definately get the ventilated discs though.

anyone know anything for the rear brakes? i kinda need to do this asap!

If you already have DR rear brakes, the stock MR/HR caliper (piston etc assembly) will bolt up to the DR legs to get you by. I believe the Z31 rear caliper (hydraulics) will bolt up to the DR legs with same size piston as DR and for rotors, DBA605 I think is the number, but it's also same as Z31 just hat hieght might be a little less which can be easily fixed with a spacer washer to make up the difference. About 5 or 6mm it is. I'm using RDA rotors on my KHR.
