86/BRZ/FR-S Bolt In Roll Bar by Alex Pfeiffer-Battleversion
 

Battleversion bolt in roll bars are in stock and ready to ship. He has two ready to go right away. I have one in my BRZ and fit is great!

These are fully TIG welded made in California by Alex Pfeiffer. He can custom make the bar to any specification you need but this particular bar he has ready-made will work great for most street/track cars that are looking for something fully bolt-in without any permanent modifications to the car.

1.5" OD .120" Wall DOM Tubing
Fully TIG Welded
Rear bases bolt to factory shock bolt locations, no drilling required
Front bases made to fit over carpet, no cutting the carpet. Can also be bolted below carpet if desired.
Harness bar is set back to allow for full travel on drivers side for taller drivers.

Feel free to PM me with any questions.

Want.

I've been thinking of gutting and carpeting the back anyways. This would be some good justification. Haha.

How much does this weight?

48 LBS in 0.120" wall as seen in my car.

Can be done in 0.095" wall to save a few LBS if wanted, can also be done without the cross bar and/or harness bar.

Car still ended up lighter than stock on the scales because of the removed back seats, spare tire and tools.

Looks good! Any chance the main hoop can get closer to the roofline? Obviously bolt-in units have some limitations, but the closer the better. Do you know if this bar is compliant with SCCA Solo 1 (Time trial/hillclimb) rules?

It's difficult to see in the pictures but the main hoop is touching the headliner in my car because I'm still running the carpeting. It can be made taller but you'd have to either remove the headliner or the carpeting for it to fit.

Don't know about the SCCA Solo 1 rules but you're welcome to email them these pics and ask, let me know if you need any more pictures either in or out of the car. Alex can always build you something more specific to your needs now that he has the basic configuration for the car, feel free to PM me or contact him direct with any questions.

Alex is planning to have a display bolt-in roll bar at the 86Fest meet in Fontana this Sunday 10/7/12 if anyone wants to check it out in person. My car will be there as well as at Subiefest in Pomona on Saturday 10/6/12.

price?

Also any pics of where it touches the floor behind the seats? can it be bolted down there if done under the carpet? Is that even needed?

Sorry, don't know a whole lot about roll bars.

To begin, the rules say the bars must be 1.75" in diameter.
This one is only 1.5"

$850 in the configuration seen in my car. It can be made for less if you leave out things like the cross bar, harness bar, quick connect couplers, etc..
You can also add things like rear strut bar, X-Brace, etc.. as needed.

I didn't take any pictures of the bases behind the seats, they are square plates with three holes that lay flat on a flat portion of the floor pan. In my car they're on top of the carpet but some people will choose to trim or fold back the carpeting and lay the bases directly on the floor which will work just as well. It all depends on your preference, most people like the fact that it's easily removable and can easily be put back to stock if you ever decide to sell the car.

I remember there being something in the rules about the "weight class" of the vehicle, IIRC anything under 3000 LBS or 2800 LBS can be 1.5" DOM 0.120" and over 3000 LBS needs to be 1.75" ERW 0.120" or DOM 0.095". Don't quote me though since it's been ages since I've looked over SCCA rules.

For the majority of street/autocross track cars that this bar is aimed towards 1.75" would be overkill, too bulky and too heavy. If your racing class requires this, it can be done no problem but I'm pretty sure at that point you'd want more of a permanent weld in bar/cage.

did you need to remove the rear seats, or did you just choose to?

Is this even safe?

what is the purpose of this bar?

I chose to leave out the rear seats, spare and foam/tools.
The rear bench, and spare fit right in.
The foam pieces that hold the tools and carpeting would have to be trimmed similar to when you install a rear strut brace.
The rear seat back rest can be left folded down, it would need to be trimmed along the sides to clear the bars if you want passengers to ride in the back. You could always remove just the rear portion or the whole bar in 10-20 minutes if needed.

Main purpose of a roll bar is to protect in case of a rollover or accident.
It also provides a safe place to mount harnesses, it can be argued that running a harness or even a fixed back bucket seat without a roll bar with harness bar is unsafe.
Another benefit is the added stiffness/rigidity provided, the car feels more solid around turns. I used to hear the "rear deck popping noise" before the bar went in, now it's gone. This leads me to believe that there is less flex in the chassis.

I'd be interested to see how this looks with most of the interior still intact, and to see how this sits behind the seats. Does the forward bar/plate just rest on the carpet? If so, wouldn't that mean the entire thing is only held in by the four bolts in the very back of the car?
How long does it take to put in and take out? Do the rear seats have to be removed to install it? Obviously the foam and carpet in the back would have to be trimmed the first time, and likely removed to install this "cage" but does anything else have to be REMOVED to install this?

It can also be easily argued that running one WITHOUT harnesses and a fixed back seat is just as dangerous.

Rear strut mounts.. not sure I trust that when the weight will be distributed on those very small extensions to the strut top. Not a fan of using the strut mounts anyways.

I assume there are backing plates included? Pics?

For that insane price (for a 4 point) the cross bar should have a short bar added between it and the harness bar, and some harness guides wouldn't be a bad idea.. not needed but it never hurts as an option.
