I've been working on a good, lightweight solution to mounting the 2g rear differential into the 3-mount subframe for the past few months. What I've noticed, is that the differential likes to rotate around the passenger side bolt that's on the front mount. The driveshaft gives the differential a torsional force like a helicopter, resulting in breaking the far left diff cover bolt (force x radius). Of course some are even breaking both diff cover bolts, because once the left lets go the right side bolt has twice as much load to hold onto. Well now the days are over where you take the entire rear end of your car and you can have 4 solid mounts just like the 1g's and evo's.
The mounts are 6061 billet aluminum and weigh 1.2 lbs a piece (stock weighs 2.4 lbs). The third piece is 1/2" thick, water jet cut steel. I had to drop the subframe to weld it on because it's too close to the gas tank. I was able to lift the entire subframe with all the suspension parts on it by just the mounting plate.
