Is it worth paying extra for the uprated arb's over the r32 kit? My car is standard set up S3 but have aslo been thinking of the Koni Fsd Is it advised to have a better suspension set up(Arb/Koni/Eibachs) if doing the Haldex? I think my arb is knackered anyway(Cloncking & Creaking) so was going to change this anyway. Will fitting just the Arb's & Haldex improve the car that much? Thanks!
