Thanks for the reply Brendon
That link is a GREAT find - Thanks for sharing!
You are the second person that has told me that "some" of the aftermarket subframes aren't that strong, must be some truth to it. While for me, finances determine I stick with the stock sub it's good to know it can be brought up to todays standards. The one limitation that still remains is tire size, correct? The aftermarket still holds an advantage.
I have already done some of the things you suggested: solid mounts, subframe connectors and a 6-point roll cage - these have really stiffened the car up! Some forward struts would really help alot. If you think about it the whole front subframe is held to the body with just 4 main bolts!
