First off, thanks to Mark Conolley at McB Autosport for taking care of the acquisition of this bar, Mark orders alot of bars and cages from Autopower, and had a very successful first year in SCCA Club racing in 2001. And I want to encourage readers to check out Travis Higdon's Autopower Rollbar Install page at the ITRCA, i used it as my primary reference source, hopefully his page in conjuction with this one will prepare you for anything.
The bar is a 4 point with removable cross members, painted black from autopower. Most autopower bars i've seen arrived somewhat beat up from shipping (indeed Travis's bar, while unpainted, was shipped without any wrapping). Mine came double layered in thick plastic, which protected it very well during the shipping process, there's only one place where i'll need to do some touching up (more for protection from rust than for aesthetic reasons, the bar will be padded when it's in.) Let's get to the pics:

Here's the bar, as it was shipped.



One of the joints where the crossbar meets the main hoop. That's Mark's hand, he was working on a triumph or something before i came to take pics..not the first time a mechanic has gotten dirty working on a british car.

The foot of one of the rear bars, which will mount to the top of the wheelwell.

The bar comes with 4 backing plates (mount under the car and in the wheelwells to sandwitch the body between the bar feet and the plates), a mess of bolts and nuts (they give 2 nuts for every bolt, I will be replacing one of the nuts on each bolt with a Nylock nut for added security), and two longer bolts for securing the rear bars to the main hoop assembly.

The backing plates come unpainted, and will rust without protection

One of the hoop's main feet, which mount in the rear seat footwells.

The only place where the plastic wasn't enough to protect the bar during shipping, a minor space (a quick spray of rustoleum gloss black will take care of this)

A look at one of the rear bars
At this point, i took the hardware home with me (i'll be installing the bar soon, when i can get a friend and Mark has space), grabbed 12 3/8 inch Nylock bolts from home depot, 24 3/8 inch grade 8 washers from Pep Boys, and a very angry 3/8ths inch DeWalt Cobalt drill bit to make punching holes in the body that much easier. I also picked up a can of Rustoleum autobody primer, and some rustoleum gloss black spray paint.

Priming and painting the backing plates will help them resist corrosion when they're bolted to the underbody of the car. Matt suggests that my painting these was premature, since i may have to bend them (particularly the rear ones)....he's probably right, but like i said "we'll see, mr smarty pants." Stupid engineers think they know everything...(mutter mutter).


Interesting sidenote here, I drove with a friend to go-karting in Columbus with the car's interior stripped (hence the rear speakers beign in, for what good they did)....at 80 MPH, the rear of a stripped R is pretty freaking loud...there is no sound deadening on the metal like most cars, so you hear every pebble you drive over...the wind and tire noise is impressive...and little things like the constant whine of the fuel pump and the sloshing of gas in a baffle-less R tank whenever you come to a stop...it's pretty amusing, but i wouldn't recommend it for long trips. A track car, on the other hand... :)

before

after, be mindful of these as they tend to want to return to their home, and we can't let them do that yet.




My bar fit pretty damn well right from the word go...it took a little pulling to get the rear bars to get past a few ridges, i'd recommend using the plastic that the bar was wrapped in to protect your car's interior paint as you move metal near metal. I assume the same bar is made for GS-Rs, notice the headroom.

Not too tight, or you'll loose feeling in your leg and foot.

Take a small thin crowbar or whatever you can find, and pull the three plastic tabs that hold the carpet in the rear. Fold it forward, you only need a few inches.

As a universal rule, the right tool for the job will reduce your pain and suffering tenfold. The metal in the body isn't that thick, but why deal with a regular drillbit. Go drop 10 bucks on something super angry, you'll be glad you did. Now, make sure your bar is where you want it to stay, because we're about to pass the point of no return.

Starting with the footwells, drill a hole on one side...

and put the bolt in to keep it from moving around. Mirror this hole on the other side.

Now, do a second bolt. You won't be able to get to the third hole on the passenger side beacuse of the diagonal crossmember, we'll get to that soon.


Make sure the backing plates line up as well.

Time to put holes in the back...same as before, mirror your actions, one bolt at a time.



Now you have 11 of your 12 holes. At this point, i removed the rear bars, and folded the main hoop into the front of the car, rather than take it out again. Replace the carpet holders, and use an awl to locate the holes through the carpet.

The awl goes in...

move up to a larger phillips-head screwdriver

and finally, put the bolts in through the carpet.

Now, we're going to take our utility knife and cut the carpet out. Part of the carpet is thin, part has super mess padding that doesn't like to be cut (but responds well to tugging) Cut a little inside the lines.



Now we have plate and foot-sized holes in our carpet.

Here's the plate in with the carpet cut out...drill that final hole with the plate to guide you.

Snug the clips around the bar, but leave the back loose.

The bar goes through the speaker hole...you may have to trim some of the plastic as it's a tight fit, i'm sure there's variation between bars.

Now we're ready to bolt it down!!

Put the bar back into mounting position, with all the holes lined up and ready to take their bolts. I put mine in with all the bolts going up into the cabin, to prevent scraping of the ground and digging into the wheels if i ever lower the car. I also bought washers for everything, as they did not come with the bar. Rather than use two regular nuts, I opted for one nylock nut at Mark's recommendation.

Using some serious Wurth body-seam sealer to keep out moisture and such, goop up the plate and get ready to put it on. (this first plate was the result of a failed loading into the caulking gun, hence the haphazard application). Tighten everything down pretty hard, you'll hear some creaking as the plates sandwich any contours in the body flat. It helps to have a friend holding the bolt with a wrench while you ratched the nut down inside the cabin.

Here's a fenderwell plate after being secured.

and a bottom plate

My god, i have a rollbar!

The seats can go all the way back and recline a few clicks with everything in place...plenty of clearance.





The only problem I encountered is that the passenger side rear seat hits the diagonal bar if you try to fold it down...i can't lock it into the mounting posts. If i were to use it as a seat, i could lock it in...but for now, i need to leave it unattached at it's base, lying flat. You can see that it's back a couple inches from the driver's side rear seat.
