I have a 91+ with the following suspension mods: subframe connectors, koni/eibach, polyurethane bushings, strut tower braces and h-brace. I frist used Firestone Firehawk SZ50s in size 225/50-16zr, which I loved and quickly drove into the ground. I now have Yokohama AVS ES100-16wr and love them. They are comfortable, and have great wet and dry traction. They also have a good wear rating and an aggressive tread pattern. I highly recommend them. I do not have personal experience with the Kumhos, which I know to be a perennial favourite, but I do know that they require an odd rotation schedule and are on the whole a more noisy tire, though they are reported to provide a slight edge in dry traction over the Yokohamas. One last suggestion- buy from the Tirerack. They have good prices and know the most about tires.
