Super extended wheel studs... oh yeah.
Tools required:
Impact gun
Standard size sockets up to 13/16th
Metric sockets and wrenches up to 19mm
Bunjee chord or coat hanger
Grease (not required)
Grinder of some sort (bench grinder would be ideal)
Big drill bits or a unibit
And other crap
First off, this setup requires you to convert your studs from metric to standard. Might as well, 12-1.25 isnt the most popular size and finding them for our cars can be a hassle. You can go 12-1.5 but then again your stuck with all those honda sizes. Also my other reasoning is, standard sizes are a hair bigger and every little bit counts.
It also requires you to run a wheel spacer with a minimum thickness of 5mm. (slip on)
Also before we start off, I did this with a s14 hub it will also work with s13 hubs. This will not work with the stock 200sx hubs. The 240 has a hex diameter of 14.25 and the 200 is 13mm.
Ok, now you have sat long and hard and decided you wanted to go ahead and do this. Get on your boots cuz we are going to Oreilly's Auto Parts.
Ask the guy at the counter to look up part #610-144. Careful some didn't have as much thread as the ones I used so be sure it looks like the ones in my pics.
The bolt specs are:
Hex diameter/ knurl: .561
Length: 2-7/8
Shoulder: 1-7/8
It should look like the stud pictured.
Oh and don't forget your nuts, I used part #611-093.
Well lets get started!
Bam get those wheels off hurry. Pull your calipers using the two 19mm bolts which hold the entire caliper and bracket to the hub. I use a bunjee chord to support the calipers in place while I work. Pull the discs and beat those old studs out. Once you get that done now you will be required to do some modifying to you rotors and to the studs to make them compatible.
First off you will need to get the studs ground down just enough to where you can't see anymore of the knurled portion where it isn't needed BUT! Remember to leave enough knurled end to grab into the hub. Make sure you keep the contour of the ground down portion smooth, flat spots or sharp edges will make good grounds for stress cracks to form. Like the picture shows... you might actually need to take off a bit more then I did. I later on went back and took off what was required for the calipers to fit all snuggly, it's your call.
Ok no you will need to modify you rotors just a bit so it will clear the larger portion or the stud. I used a drill bit but you can also use a uni-bit, I choose a drill bit because it is a little more percise and comes out lookin better. Choose your weapon...
Alright now that this is all done up, we can carry on to the assembly. Grab that impact wrench and throw in the stud, add some spacers like modeled in the picture. Make sure you will have enough room to clear the threads when the stud is fully compressed.
Hammer on it until you see the backing of the stud rests securely against the hub. If you arn't 100% you can try and fit a peice of paper in between the backing where it seats againt the hub or listen for a change in sounds while you are using the impact. It will go from a light tinging to the whole hub rattling. Also a little grease on the knurled portion of the stud can be used to smoothen the pressing process.
Now you can go ahead a start reassembling your brakes. Hint: somtimes after installing new studs the rotor will be hard to slide over the studs. This is caused by the studs not being 100% lined up. Just horse around with it until they slide on, don't hammer the studs because the initial perpendicular shock can weaken or even crack the stud reducing its shearing and tensile strength. Make sure your brake lines are in the same position then came off at, no twisting or hard creases.
Ok now you got them all in it should look somthing of the sort...
Ok now get you damn wheel on and check that shit... Don't forget your spacer!
BAM! now get your ass out there and put them studs to good use. Keep it rubber side down.
