I too had the same dilemma, bought the WALK and feel it does certainly help traction. Combined on mine with Bilstein B12 kit.
We had some fitting issues, well removal of original parts to be strictly accurate, in my case the console bush which the WALK replaces had two sheared bolts out of three attaching it, once that was off the car the ALK went on fine.
Ordered the Eibach ARB kit last week, as I flagged in RANDOM chat, found that C&R Enterprises was the best price if that helps. Looking forward to see another incremental improvement.
Bloody slick this slippery slope of modding, I started with just a remap.
