I'm late to the party and i have no personal experience on my own vehicle or the pics anymore, but i was there when my buddy removed his UPR K member from his '04 Cobra and one of the welds had cracked. The car only had about 200 miles on it since the install. there are pics and i'll try and get them. it's been probably 8 years. either way, ever since then, i've been anti UPR, i gave them another shot with their coilovers on my '98. I know it's not a k member, but speaks volumes about their customer service or lack thereof. i had issues, i called them, nothing, emailed them, nothing, used the contact form on their website, nothing... QA1 and UPR are the exact same, so i group them together. i helped Caleb install his Team Z on the smurf and it was a little pain, but we got it figured out, and they stayed at the shop late the day we did the install, in case we had anymore questions, so i was super impressed with their customer service. I also run their tubular rear street beast control arms on my car, and will be purchasing their k member soon.
