Watson Rollbar Install
After the last track day, I realized it was time to step up the safety aspect on the car before any more go-fast mods. So, I bought a Watson Racing 4-point roll bar and a set of G-Force 6-point harnesses. I know not everyone around here likes the Watson bar as much as the Maximum Motorsports one, and without my need to retain use of the back seats for DD duty, I likely would have gone the MM route. As it is, only Watson offers the ability to set the bar up to be a bolt-in/bolt-out affair, so that was my only choice.
Sourcing the bar became something of a comedy of errors. They were supposed to be in stock, but after a few days it turned out they were going to powder coating. So an additional week waiting; not a huge deal in the grand scheme, but a little frustrating. Then I mis-remembered the street number where I was having it shipped (not to my own home); thankfully i have a nifty shipment tracking app and intercepted that issue with only a couple days delay. Finally, the box was completely trashed and the hardware bundle & instruction sheets were nowhere to be found. JDM & Watson jumped on that & got me the missing parts before the weekend so I could still get the install done.
Anyway, on to the install.
First was to remove all seating and the rear quarter trim.
Then, set the main hoop in place and mark the OEM B-pillar gussets for drilling. I took the advice from previous installs posted on the board & drilled 1/2" holes to allow wiggle room--that was a good tip. Once the gussets were removed & drilled, they got loosely attached to the bar.
At this point I ran into two manufacturing issues. One is powder coat thickness. I had to do this eventually to all the welded-on nuts:
(not sure what happened to this file, but you get the idea)
They pretty much all had their threads gummed up and had to be chased out with a tap.
The other is I also found that the holes in the bar's feet all had just enough to make the holes barely allow the bolts, AND a couple were just far enough off that the plates could not fit correctly even without the OEM gusset involved. In the end, I had to slightly hog out all the bolt holes on the feet. Getting everything to align on the main bar became a bit of a circus and I was wishing Watson had done what MM did & just fabbed up a gusset with the proper threaded holes ready to go. As it was, I ended up having to abort on the first day due to these issues & a late start.
After taking a break to blow things up on Saturday, I started early Sunday and got the alignment issues resolved on the main hoop. I elected to spot-weld the nut backing plates in rather than screw around trying to align & drill more holes to rivet the plates in place. No pics as it's been ~8 years since I welded. Suffice to say the tacks are ugly, but sufficient. No, I won't make a living off my welding "skills."
Anyway, got the gussets all set up & finally into place.
Next up is the downtubes. These proved much easier and seemed to almost drop into place. Happily, Watson DID remember to mask off the interlocking parts here, so they fit great. The feet land right on top of a sheetmetal seam, so seam sealer needs to be chiseled out of the way both top & bottom. At this point--being tired--I made it an official car project.
I was kind of anticipating doing this so reacted quickly enough that I only jabbed myself *just* enough to draw some blood. It's not an official project until you bleed on the car, right?
After setting the downtubes in place, I got the shelf marked & drilled. Then had to crawl under the car & pick the seam sealer out of the way underneath. That was almost the biggest PITA of the whole project.
Once that was complete, it was a simple matter of putting the downtubes back in place for a final test-fit, then putting some RTV form-a-gasket around the perimeter of the backing plates & around the bolt holes and bolt it all up.
So the semi-complete project:
It was getting later in the day at this point & I had already decided to save cutting the trim panels for another time. I ran into a challenge with the harness mounting, so that will be the next project.
