I just wanted to let everyone know, if you didn't know yet, about something I just discovered. The braces that go across the exhaust tunnel in our cars are compatable with the MS3, or should I say vice versa. I just finished bolting these on, but didn't get to test out its toll on torsional rigidity. I also didn't get to take a comparison pic of the front brace (right under the downpipe with the shield for the fuel lines). But here is a pic of the mid brace. MZ3 two single thin braces on the left, and MS3 one piece thick brace on the right. Direct bolt on alternative for G-Spec braces or such for MZ3 owners.
