I pulled my r32 diff apart to shim it and found it had 2 1.10mm shims standard! Already had 2 1.2mm shims to put in it instead of the rumored 2 0.80mm shims, oh well, put in 2 1.10s and a 1.2 total 3.4mm, way too tight! lol. Pulled it back out and put in a 1.49 and 1.2 total 2.51 couldn't really feel it. Then tried a 1.35 and 1.49 total 2.84 not bad, still slightly lacking lock. Then tried 0.75 0.95 and 1.49 total 3.19 too tight again! It is bloody touchy and hard to get spot on! Seems to be either locked or stock, their might be a 0.3mm window that you can fiddle with to get the desired results.

I've seen another diff with 0.75 and 1.35 in it when pulled apart!?

Not sure if after all they are 0.80mm both sides all the time, other people measured their old shims once their out?

Yeah one of my mates used a battery powered snap on rattle gun for his. I headed up to Beaurepairs and the guy there rattled them off for me for free which was nice :P

Just went for a drive then and definitely a big noticable difference using a 1.2mm shim. Clunking and shuddering like a mofo around tight corners haha :D Seems to hook up pretty well though out of corners under power which is just what I was after.

So yeah, all in all pretty pleased so far, will just have to wait till Thurs to see how it holds up at Wakefield...

hey mate, how did the diff hold up at wakefield? would loke to know

Thanks for the tutorial, it was easy to do with your instructions. Put 1.49mm shims on both sides and it's REALLY tight now, inner wheel jumping in tight corners. Can't wait to test it on the track. Hope it loosens a bit after some driving, that's what I understood from other posts.

By the way, is there a specific place were the breather hose should be? Couldn't find any.

tis a long story haha

you'll be happy to know that swanny180 thoroughly enjoyed the diff at the track as the inside wheel doesnt light up coming out of the tight hairpin.

however a crown wheel bolt dislodged about a week or two later. this broke the diff casing and required an expensive towing of his car! make sure those bolts get done up tight, impact wrench tight.

Hahaha sorry hadnt seen this earlier... But yep thats basically it.

Brilliant traction out of tight corners, its surprisingly noticable.

Diff is quite clunky and tight on the street, but if it is traction you're after it definitely works.

As IntercooL said I made the mistake of not doing up the crownwheel bolts tight enough, so ended up with a nice big hole in the rear cover of the diff where a bolt made its bid for freedom, and about a litre of diff oil spilt through the uni car park... ...woops? ;)

So yeah moral is that its a decent cheap mod for the track, isn't the best for the street (ie girlfriends don't like it much) but is tolerable, and you NEED to make sure the bolts are loctite'd and done up farkin tight.

Hope that helps :D

hey guys i did this mod July 2007 (look at page 2 on this thread), just thought id let you all know how its going. One year and three months later, its still the best mod i have done to my car. my car now has 280rwkw, a roll cage, no rear seats, racing seats and harnesses (taking my drifting pretty serious theses days lol) but still after all the mods the diff is still the best. held up perfectly now for 5 full drift track days plus all the street driving i do as well. hasn't missed a beat. GO the shims!!!!!!

put some loctite on those bolts and do them up tight. put it on all of them including the housing and the bearing caps not just the crown wheel and pinion

I assume from your for sale ad that yours is still going strong Trust33?

i am tossing up whether to go all out and get a kaaz/nismo 1.5 or 2way, put a spool in it or shim it, judging by this thread shimming seems like a cheap effective option.

would adding a shim to a single spinner make it a shimmed diff & make two wheels spin ?

no will only work with an lsd, if your talking about a skyline though, i believe all are lsd in which case shimming should work.

in the off chance you do have a non lsd then your cheapest option is a mini spool, or welding.

cool thanks mate,

its a NA so yeah no LSD. will just keep hunting for a complete LSD then

Dont be scared of a locker, they are not as nasty as people make them out to be, my diff stuffed up in my old rx7 and a mate locked it, i was too scared to drive it at first (it was raining the day we welded it) because of everything they were saying about a locked diff, but once i drove it i realised its not as bad as people make them out to be, only really notice it on tight round abouts u turns and parking, even then there very manageable, and one your having fun they are very predictable, will always do the same thing at the same point.

Dont know what a spool is worth but if its only $50 then its worth getting one to try it, if you dont like it put it in the for sale thread and get your money back.

Hey guys,

Thinking of doing this to my daily driver... just wondering if you could clear some stuff up for me as ive read through the thread and there seem to be alot of different ideas.

What sort of total shimm should I be looking for?? (2.0mm - 2.8mm?)

Is it better to leave the old shimms in and simply add the extra shimms or to pull the old ones out and replace them with bigger single shimms on either side?

Lastly should I load up each side with the same amount ( 1.2mm either side) or doesn't it really affect it?

Much appreciated guys n awesome writeup.

Cheers

yeh i had a locker in my old onevia. didn't like it for daily street driving (drifts and donuts are awesome tho) too harsh when i do low speed turns/parking etc. the sound got annoying after awhile.

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
