Well, after more than a year of owning an O-Bar, I
FINALLY installed it this afternoon.
Total time: 3 1/2 hours, this includes jacking the car up & down, and heading to the store to get longer bolts.
Time taken for the first hole: About 15 minutes.
Time taken for last hole: about 1 1/2 minutes.
Hints that worked for me:
If you don't have access to a floor jack to put under the drill to apply pressure, use a 4"x4" chunk of wood and a really long screwdriver (Or other long strong and stiff instrument) to apply pressure like a lever. Works like a charm!
Once the first hole is drilled, use one of the bolts to hold the bar up for the rest of the holes on the bottom.
Definitely use Cobalt drill bits! Expensive, but well worth it! I can't imagine how many regular bits it would take to drill through all that steel.
Make sure you wear safety glasses. You can't drive too well with metal chunks in your eyes.

Lessons learned:
Wear gloves, those metal shavings are hot! Plus your hands won't get as dirty. (I only drew blood twice, but had
many slivers of metal in my hands.)
I do trust the locknuts, but I bought slightly longer bolts and used lock washers along with the locknuts. Extra insurance, ya know!
If it's raining during your install, put down a tarp and make sure the water doesn't run over the edges of it! My back, from the top of my head to my heels, was dripping wet by the time I finished.
First driving impressions:
This thing kicks

Even though it was raining for most of my install and subsequent drive, I could tell a difference immediately. Someone said that the O-Bar makes the NB more like a go cart, and I think I believe them. (I'll know more after the roads dry out!)
I am kicking myself for waiting this long to install it.

It is totally worth the $100 for the O-bar, plus the $25 in Drill bits, and a wet backside!
I totally recommend getting an O-Bar! Do it now!
