Just throught i'd post up my brake upgrade info,

what i'm doing is using s-13 coilovers and hubs, redrilled r32 gts-t rotors and 4 spot calipars. from what i've been told by a few people who have used this method is that it will work?

started with the rotors and calipars picked them up both front and rear for $410.

next is the s-13 coilovers which i've lined up a front set of JIC ones that have just been recoed and will set me back $690.

hubs are a bit of a mystery at the moment as i'm waiting to here from a couple of people. looking like beening anywhere from $200 to $360 dont know final price yet.

this is as far as i'm at at the moment! i know what the process is but will take it step by step over the next two weeks pics of each stage will be provided..

anyone with helpful ideas....

Not trying to re-direct too much,but what was the conclusion about HR31 struts into R30?

HR31's have the same 100mm caliper spacing as S13/R32,etc,so the 4 pots would bolt straight on,and the bigger discs slide straight over the hubs (after redrilling to 4stud) as they're not a single piece,as in the '30s.... Might be a cheaper way to go?

ps-are you wanting to go 4 or 5 stud hubs?

i did think about it but there not as eazy to find as a set of s-13 coilovers, i can get a set of jap spec r31 struts but they have the aus r31 rotors and calipars on them so i'm thinking there not what i'd need. i just dont want to have to import the bits..

i'll keep it 4x114.3 stud pattern

have a look in the for sale section for the going prices on the gtr bits..

got the hubs lined up yesterday for $200 so thats all the bits i need.

total has cost me $410 private sale

$690 local importer

$180 private sale

--------

$1280

theres a little bit of machining to be done to get some bolts to fit

other than that the next expence will be new pads, fingers crossed.

I have just done this myself. One thing I found is that I had to modify my strut tops to get any decent amounts of camber, as the s13's are 180 degrees out. Just elongated all 3 holes in the camber tops.

I have just sorted r32/33 brakes on to DR30 struts for a mate too all that is needed is a 10mm spacer. and hubs turned down slighty.

any tips or things i should look out for as i've just got the coilovers and habs today?

i'm working of the info from the 910 site i think phat or someone else posted up and have posted a few questions in the forum, looks like theres no wories with the front

here is what i have so far, i have the hubs too but no pic at the moment:

i need to put the work of for now as i'm having trouble getting an auto electrican to finish the last few bits.

  • 5 weeks later...
In the future I hope to use R32 GTR bits on my DR30 . Do you know if GTR calipers use larger pistons that the GTS-T(R32) and are the pads the same . Hate to ask but what would the GTR bits cost ?

Yep the GTR calipers are much much bigger, if u hold them side by side with a GTS-t caliper you'll notice the difference hey, the GTR also uses a bigger rotor!!

I cheated, i bought Crimmo's setup hehehehe :);)

found out today my machanic is on holidays till the end of the month, so i'll get the work done when he gets back, i'm working on a +35 offset for the front to fill the gaurds got the rims allready 17" P1 racing, i've put them on the car once so far and there is a bit of a gap so i'm hoping the coilovers and s-13 hubs will sit out more...

I got the s13 set up running. using some wheels I have not sure on the offset but they are about right on a 180B and running 30mm bolt-on wheels spacers with around 3.5 degrees camber they sit flush at the top of the guards at the front and stick out a fair bit at the bottom.

I drove the car around for a day with the front wheels in the guards just and the rears almost with the rim itself in the guards with about 70mm of ground clearence to the chassis rails and a lot less for my exhaust. Looked damn tuff but I chewed out a drive shaft CV in under a day so jacked it up a good 1 1/2 inches the next day. Still sits damn low, but plenty of ground clearance for everyday driving.

My front end is now all done., sits tough on the ground, low enough to look tough, but not low enough to create attention..I've got 215/45/17's on the front and it fills the guarsd out nicely as well!! needs a bloody wheel alignment though something cronic haha!!

    • Did this end up working? Did you take some pictures?
    • 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
