This sounds like a good opportunity to replace with anti-lift kit, stiffer front bushings and lower springs like VWR / Eibach etc. It would be rude not to save @6kg of unsprung weight by using alloy control arms and hubs whilst you have the opportunity, though these can be sourced pretty cheaply off Passat B6 rather than S3. Your overall bill will be much the same but you will end up with a better handling and more responsive steering.
