I completely go against H&R and say Whiteline.
Not sure how the whiteline ARBs can rust as they are powdercoated and if you grease the bushes fine they make no noises at all. I didn't notice any.
They are the best bars and get forgotten about because they're the underdog brand name and "only 24mm" but there's more to ARBs than the width
I got mine from DPM on my TDI and could not fault the bars or the service as per usual with Damian.
Only word of warning is those with JOM coilovers should not mix hard ARBs as you'll be snapping drop link brackets every 3-4 months .
