head over to the RSOC and look for the rear tie bar thread in the S2 section.... plenty of info and pics about these bushes and wishbones as ive just been shot in the foot by fooking flo-flex crappy bushes. Powerflex all the way...... turns out Flo-flex actually sell smaller bushes that you need but funnily enough me and someone else bought the same kit and both were the wrong ones. Flo-flex have fooked up their end and wont admit it.
DO NOT buy Flo-flex as per the thread posted in the RSOC S2 section.
