I had planned to replace all the hardware this winter, as after three years of use I was having anxiety about this. How ironic...
The one chronic problem I have had with this kit is the hardware loosening. Numerous times I've had shudder issues on track only to find that one or more of the nuts had loosened. I was also worried that the top nut on the outer ball mount may have been stretching the stud every time it took more torque. I even talked to Sean about this. Looking at the failure, it suggests to me that this stud did stretch as the failure looks to me like a tension failure rather than sheer.
For now I'm going back to stock arms. Will be interested to get Vanne's feedback on the MRT DTM kit.

Well this is concerning! I have had the same kit on the car now for about 1.5 year but I haven't had the car on track much this year due to covid. Now I am bit worried to because of this failure.
The only thing I will say is I didn't really had the hardware loosening issue. I have had the arms off the car once since installing them initially and when I did a re-torque after about 500 street miles I only got one or two nuts that needed a tiny retorque. Then after that they stayed put for the next 3Kish (track/autox/and back road carving) miles until I took them off again.
Have you been in contact with Shane at all about the failure? I am wondering if all the nuts/bolts on this kit should be wear items.
