Rear sway bar for MK6 Golf GTI

[Lucas_R]

Hi all looking to pick up a rear sway bar for my GTI. What size does everyone recommend?? 22mm, 24mm?? The car has lowered springs if that is helpful.
Is this good bang for buck handling upgrade??

Thanks all

I got the SPM swaybar recently from DubAddiction. Well priced ($280), fits well and does the job.
