Installing a rollbar increases...
Installing a rollbar increases safety and rigidity, and it looks downright cool!
Though I’ve been a racer for many years, I haven’t given as much thought to my own personal safety as I have to going faster. Because my cars were usually my daily drivers, I always felt the installation of a rollbar would be too invasive with all the welding, and it would take up too much passenger space, thereby hindering the vehicle’s use.
A wake-up call came when two close friends were involved in on-track incidents that were both diffused by their cars’ rollbar systems. "This could happen to me," I thought. What made things even worse was a crash that occurred at Sebring when I was there in May 2010. A Mustang hit the wall going backwards and while the driver was perfectly fine, it clarified just how dangerous racing can be.
After breaking the 130-mph barrier on the track at Sebring and taking corners at high speeds, instructor Jonathan Blevins suggested I seriously consider a rollbar and harnesses for my ’05 GTO. And in the months following our track experience, I’ve been slowly upgrading the GTO in a few areas, including safety.
Since my GTO is a primarily a street car that I take racing, I don’t want a welded-in rollbar, nor do I want the installation to take up too much passenger space. However, I do want improved safety, a place to mount a harness, and an easier and less permanent installation than welding. With those considerations in mind, I ordered a Street-Sport rollbar from Autopower Industries. It’s a bolt-in rollbar system that incorporates a detachable harness bar and was also built to meet IMSA regulations, which covers my Performance Driving Events track outings. This particular product is not NHRA-legal. However, since the NHRA only requires a bar for 11.49 e.t.’s and quicker (13.49 for convertibles), many street cars aren’t quick enough to require a rollbar per the NHRA rules. Simply put, installing this rollbar in an 11.50-and-slower street car is still safer than no rollbar at all. Priced at about $520, it’s relatively cheap insurance.
According to Autopower Industries: "All of our bars and cages are certified-MIG-welded and precision-jig-notched, providing you with the maximum strength and best fit available. Every rollbar or cage has been designed to fit specific car models, so only minor modifications are necessary for the installation. Most applications are a true bolt-in and require no welding."
The Street-Sport bar is a four-point rollbar made from 1.750x0.120-inch DOM mild-steel tubing. It features a removable harness mount tube, allowing the addition of a multipoint safety harness system for the track. The tube itself can be unbolted to provide room for rear seat access for street duty.
In addition to the Street-Sport bar, I also checked off Autopower’s slick Pro-Cam Driver Restraint system, which features a turn release buckle and five-point harnesses. I am installing these as a four-point system because the anti-submarine belt--the belt for your crotch area--is designed to be fed through a racing seat that features an anti-submarine cutout to prevent you from sliding under. According to Dave Young, a fellow Source Interlink staffer who helped me with the installation, "Without the correct seat, the installation of this belt could be more dangerous than it would be helpful." So for now, we will set it aside and focus on the four-point system and rollbar installation.

The Autopower Street-Sport rollbar fits in the GTO like a glove, and that made its installation a challenge at times, demanding a day’s worth of work from two people. To be fair, Dave and I took several breaks along the way, and we had to stop often to take photos.
The most difficult areas were the rear interior panels. While the rear harness bar is removable, it’s not suggested that passengers spend too much time back there as it is a bit cramped. We haven’t installed it yet, but padding for the rollbar is highly recommended to protect you and your passengers.

Shown here are the Pro-Cam Driver Restraint System and the hardware that came with the Street-Sport rollbar. There are two rear curved plates and two flat plates for the front bolts that hold the rollbar. Each mounting point is secured by three 17mm bolts with washers and nuts, and the removable harness bar and rear bars each use two 17mm bolts with locking nuts.

There is nothing more reassuring...

There is nothing more reassuring than seeing the proper SFI labels on safety parts. The harnesses are approved and ready to go. This means that it will pass tech inspection without a problem.

To begin the installation,...

To begin the installation, we removed the harness bar to simplify the mounting process. The bar is held in by a 17mm bolt, but quick-release pins can be purchased to make taking it out a piece of cake without any tools.

We started off by testing...

We started off by testing the fit inside the GTO and immediately hit a speed bump as it interfered with some interior trim panels. This bar has extremely tight tolerances therefore it doesn’t just slide into place. Once we identified which panels needed to be taken out and how, we removed the bar and started to dismantle the interior.

Behind a small plug is a Phillips-head screw securing this trim panel with the seatbelts. Be very careful how you take this panel off because the sliding mechanism for the adjustable belt is very brittle. You could find a spring and clip on the ground that you’ll have to figure out how to put back together.

The remaining upper trim panels...

The remaining upper trim panels are held in place with high-quality clips. We removed the panel by carefully pulling it straight back. The clips should smoothly release from their mounting points.

Next, we pulled out the back...

Next, we pulled out the back seats. The cushions are held in with a clever latch that has a release you pull from the bottom. Within seconds the cushions were out, and so were the seatbacks.

There were a total of six bolts holding the rear interior side panels in place, in addition to the clips. Just like the rest of the trim, we got them out easily—installing them with the bar in place would prove to be quite the opposite.

Finally, we unplugged the...

Finally, we unplugged the driver and passenger seats, and unbolted them to take them out of the car. They weigh in excess of 60 pounds each. Thankfully they’re extremely comfortable, otherwise we would have opted for lightweight racing seats.
