Don't know about the heavier? newer models, but I beat my friend's 98 GTi with the VR6 once and stayed even with him twice after that. The Jettas are heavier so I would give it to the SVT.

99 SVTC, T-Red, #652/2760-12.8.1998 Mother#@%@!* did I sound abstract? I hope it sounded more confusin than that!
