Mine didn't end up exactly like pictured. Like I said I had to move more of the spacers under the plate. I'll have to look at it when I get home.
How many washers did you add to each strut?
Mine are very Similar with my UPR plates and no issues at all. Been that way for over 2 years prob at This pointI torqued it down pretty good, but I can understand the concern. I may tighten it another turn or two to pull the threads up flush with the top of the nut.
Sound advice. Maximum Motorsports suggests that owners complete a post recheck/re torquing of all nuts and bolts once 1,000 miles have passed.Be careful not to over torque it. Tightening to much is just as bad as not having it tight enough. You might not have any problems, but one vigorous drive will not reveal if you have a problem. Follow Mustang5L5's advice and use the white out.
The nylon in the top of the nut acts as a lock washer. If it doesn't have good thread engagement it simply wont work as designed. If you do take it to get the alignment done tomorrow you could ask them about it. You might not ever have any problems. The last thing you want to do is get an alignment then realize you have an issue that requires you to bust things apart again, requiring a new alignment.
Also, it wouldn't be a bad idea to ask the guy doing the job to give everything you've done a good once over. Having another set of eyes take a look is always a good idea. That's what I did when I finally took my car to get an alignment.
