    Converting a Subaru to rear-wheel drive can be done in a number of different ways. The two most common solutions involve either completely locking the stock center differential, then removing the front axels, or by swapping out the center differential for one like the Design Craft part (www.designcraftfabrication.com). Typically, a center differential is locked by welding the spider gears into as solid mass, which is not particularly reversible procedure. Next, the front axles must be unbolted from the stub shafts in the hubs, and the axles removed from the transmission.

    Locking the center differential is key; if left to its own devices in a situation where the front axles were removed, it would just spin freely, sending all the engine’s power to the unmotivated front wheels. The viscous coupling would make an effort to shift some of the power to the rear, but ultimately would either seize or grenade.

    In contrasts, Design Craft claims its center diff can be installed by the average mechanic in about half an hour. Replacing yours tock diff and viscous coupling should take about the same time. By disabling power to the front axles within the center diff, there’s no need to remove any other parts, and converting back and forth between AWD and RWD is a snap.

    The rub, of course, is the rear output shaft was only designed to handle half the stock engine’s power. Put all the power through that shaft, then nearly double the stock output and you have one very stressed output shaft.

    After several successful drift outings, the output shaft finally snapped as soon as we pointed a camera at the car and yelled “Light’em up!”

    So this is the end artical of the story "The Beauty of Two-Wheel Drive" in Sport Compact Car April 2004*Volume 16, No. 04.

    Under his drivetrain mods it states the following:

    Design Craft Fabrication center diff
    STi three-puck metallic clutch
    KAAZ rear dif
    Kartboy short-shift kit

    This was all for a 2002 WRX wagon.

    I'm not saying to do any of this. Just pointing out what the artical said so that you can make a decision for yourself.

    Good luck and if you have any questions or if you want me to photo copy the artical and send it to you just let me know.

    Late,

    Been there done that! and still doing it. I've been RWD for a year or so, lots of drag racing and burnouts (everyone wants to see a wrx smoke the tires), all on stock parts.
    No breakage of the tranny, output shafts or drive shaft. what I did break on the 8th of jan. was the pinion gear!! I never even considered that the pinion would break, it is pretty massive.

    Alright I read the whole thread linked above and the appeal of being able to switch from RWD to AWD is pretty cool. My question is this... I tried to check out design craft's website and its no longer there, anyone know what happened to this company? Can you still buy one of their center diff's instead of making one yourself?
