To be honest, I haven't really seen any TSI FWD 1gs around BUT I just finished installing Suspension techniques rear sway bar retrofit for the 89 - 94 FWD model. Besides the installation instructions being retarded and the diagrams not matching what the written instructions are saying, the install is easy
Only two holes to enlarge as they are already there in the control arms from factory.
On a side note, this years shootout proved to be the best place to find hidden treasure. Front and rear strut tower braces for twenty bucks.. TWENTY DOLLARS!
