When I started my WRX914 ,I didn't want to modify the car to fit the WRX.
Before long I found myself cutting and welding quite a bit. Looking back, it will never be a stock 914 again. So why did I use the stock 914 X bar mounts? Like most, I am sure, because they are there. I was basing my decisions off a model for a kit (IMG:style_emoticons/default/confused24.gif) They are great for plug and play but I have a welder. Seems they are not in the best location for the WRX motor. It seems to me that the rear suspension inboard ears (Inner console) are just about the best location to tie into. The Inner console would no longer be indirectly supporting the motor but directly supporting it reducing the load transferred to the tub. It seems this would stiffen the Inner console as well. When I originally did my "cradle" I did add a little extra tie-in to the ear but it is not taking the bulk of the load. I am thinking, if I reinforce the Inner console and tap my x member 100% into the Inner console, I can remove all other "cradle" tubing. Has any one else taken this route? Any thoughts why not?

My son broke the mounting ears off a 901 transmission at a drag strip almost as soon as we mated the WRX engine. It's not relevant to this because I know that engine's motor mounts weren't rigid enough and let the motor vibrate, which was the cause, but it's one reason I like the cradle that provides support for the full drive train, independent of the car's chassis. It provides rigidity to the drive train while also triangulating the whole rear of the car, though not the suspension attachment points themselves. It seems to work pretty well. So far, anyway. Oh, and now we use the Subaru mounts too, and they're perfect.
