I just bought a set of Whiteline Sway Bar end links from Motospan and they failed literally after 50 miles of driving. I did not even get a chance to corner hard or anything. I never track my car either, regular street driving. The clunk becomes more frequent and louder the more i drive and the sounds is definitely coming from the rear. The OEM ones were shot, i could move both sides of the oem very very freely. I am thinking these end links are defective so i placed an order for a second set. If these fail then I'm going with SPL.

Don't bother with a second set. Just go spl. My whitelines failed also. They're not worth the effort.

SPL is 100% the best choice.
