Hey,

Ive got a quick couple of questions for the tech guys here regarding DR30 front brakes.

I know that DR30 struts have 100mm caliper spacing, resulting in a nissan 4 spot caliper being used, but the hub assembly isnt like hr31 (similar to s14,s14 etc) where the disk just slides onto the wheel studs, bolt caliper back on and bobs your uncle.

DR30 is datsun style (hub bolts to disk)

How do I go about fitting or modifying the DR30 hub to accept a S series silvia disk?

Please dont say "put s13 front coilkovers and bits in" as its out of the question (dr30 struts are going into a stanza)

Now the next question, anyone fit 14" wheels over dr30 front brakes?

Cheers,

Take the disc off the back of the hub (unbolt) and machine down the diameter of the hub to suit, so that the disc hat slides over the top.

The hubs are forged steel, not cast and machine very well.

Guys!

It's all to do with the OD of the disc rotor vs space in the back of the wheel.

Your wheels need to clear the caliper, simple as that and 274mm dia DR30 rotors wont allow 14's to go on.

The stock fronts are only 250 so 14 is easy then.

Cheers, D

Stock fronts?

As in just plain mr30 strut/brake combo?

Its more the caliper size that kills the fun, I have a similar sized disk on my 1600 struts, using a bmw 4 spot.

Picked up some n/a r32 front brakes yesterday( yay 14" wheels! ) soon as the disks are back from being machined ill send the hubs off to get them modded.

Also going to do a coilover convo on em using threaded colar, will throw up some tutorial style pics as I progress.

Cheers,

Dan

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
