I'm currently rebuilding my car AGAIN (lol) and want to get the front end sharp again so am replacing anything that might need replacing.

I'm thinking Rack, TCA's and track rod ends. The car already is fully polybushed so don't need them.

To be honest, none of the above components has any real play in them what I can tell but the car didn't feel as sure footed as it should be. Anyone have any comments or ideas about 100% guaranteeing that the car will be sorted if I replace X component??
