Hi Everyone I just both Audi S4 3.0 petrol 2009 and I want to update all front arms bushes and Anti roll bar bushes for high performance. Has anyone done this before and where can I buy the parts for this. thank you

Can't recommend companies but don't buy the cheap ones as they're all rubbish in my opinion 

Hello Michael,

Why high performance bushes?

Are you going to be using this regularly on track, as opposed to normal road use and driving? 
Kind regards,

Gareth. 

Meyle HD do a full front kit including drop links at a brilliant price. Certainly felt very good quality and I've had no problems since I fitted them last year. 

It's crucial to only lightly tighten when in the air then preload the suspension before torquing up. I think the pre facelift is M12 ball joints, whereas facelift has M14. Torque settings are different as well. 

It's at least an eight hour job and the pinch bolts can be a pain. A right angled air or power ratchet helps significantly. 

FCPEuro have a good guide on replacing them.
