My concern as well, as obviously the extra weight, motion and bumps, etc will put not insignificant new stresses on the mounting points and pre-existing structural weak zones of the MIC top.
“No issues, but I had my top replaced as it was cracking” seems like a bit of a contradiction. Was the top cracking *before* you put the rack on?
Where EXACTLY are the "pre-existing structural weak zones of the MIC top"? Please provide the FEA. #tool
As I’m guessing your aware if you’ve dived into the MIC top threads here, cracking is most commonly reported around the side windows, especially the rear quarter glass panels — which would be precisely where this rack has its two primary mounting points. From the TURN video it *appears* that the rack is secured to the roof in only two spots, and just ‘sits’ on the roof in the front two locations. But maybe I’m interpreting the video wrong, but I think this is all that you can do with the 2-door roof. That’s why I asked TURN to clarify.
Trust me, I'm well versed on the cluster F of issues many have experienced with the MIC clamshell. I was simply asking if you had specific info on the "structural weak zones". That would be a great tool to have, especially for those mounting accessories to the roof.
No, sorry if I made it sound like I did. The big interesting question might be: Is there any correlation between racks and cracks on the wide population of vehicles with MIC tops and various different roof racks? It’s likely more an issue of just getting lucky with the MIC top manufacturing batch you happen to get, but like I said, all racks and added weight add *some* amount of stress. I’m just trying to figure out if a rack is worth the added risk of MIC failure, or if the addition of a rack = negligible additional risk. Impossible to really know I guess, but good to hear no reported issues with this one.
No, the cracking was no where near the contact points of the rack. I believe it was more from stresses of the rear window opening and closing. My dealership has done all the service on my Bronco, knew of the rack and replaced my top under warranty.
