[SVX10]

Mychailo,
I'm out of town this week, so I can't get a pic of the crossmember up. Here's a description though...

From the front crossbar under the engine, I go straight back about 3/4 of the way to the stock crossmember with thick walled 1.5" piping. At that point, I connect the two "runner" pipes with 2" or 3" wide channel steel (2 pieces welded back to back to create an "I" cross section). This is where the stock WRX rubber mount bolts to. From there, I use a 1/4" thick steel plate about 5" wide to connect to the stock crossmember (it covers about 4" gap). I originally had the 2 runner pipes going all the way back to the stock crossmember, but they interfered with the exhaust. I was thinking about reinforcing the entire structure with 1/2" cold rolled steel. All welds are full seam welds...not spot welded.

Other than the stock WRX rubber mount, I have no other means of vibration absorption (but neither did the stock SVX)

Beav,
I understand what you're suggesting I look for, and I will. However, doesn't my final test point toward either the engine angle or the trans crossmember as the root cause?
