Should be 100mm. The hr's i think have the 88mm. You could also install import Hr31 fronts, they have the same spacing 100mm

The 'big' 274mm discs have 4" (101.6mm) spacing, the small brakes are 3.5" (88.9mm).

Ahhh, the legacy of the imperial system...

so i should be able to put r33 brakes on them? or not possible?? cheers Paul.

does anyone know it would prob be easier if someone could tell me instead of buying r33 brakes and trying and not succeeding anything will be great cheers paul.

If you've got proper DR30 struts then yes the R32/33 calipers will fit, the rotors are smaller though, if you want a bigger rotor get a R33 non turbo rotor, still 4 stud

HOWEVER...

Fitting wheels over the 4-spots is a bit of a problem, as the calipers prodrude further than the OEM R32/33 fitment. As a result, with the stock alloys, spacers of about 20mm are needed. That doesn't do much for the scrub radius, or the axle bearing loads. The best 4-spot as far as this issue is concerned is late S13 - they are designed for a 22mm disc as opposed to the Skyline's 30mm.

I can't even get my 16" Watanabe F8's over a set of R33 calipers.

I've just put EBC Green-Stuff pads in my DR30, they do the trick.

Unless you want to stop from 200mph at Caltex Chase, I think you will be very well served with good pads in the DR calipers.

EBC can supply Green & Red for fronts and Black & Green for the rear. My advice is Green & Black for normal road use and Red & Green for track & competition, but if not available Bendix Ultimates are a good alternative up front.

To fit BNR32 GTR fronts, the hub has to be machined to allow the hat of the rotor to go over, you will be amazed at how close the hat height is compared to the standard DR rear mounted rotor and the big advantage is the solid 4 spot caliper, no flex as you get from a sliding single caliper.

But as I said, unless your trying to stop from very high speeds, I don't think they're necessary.
