For sale I have build custom fabricated 4 point roll bars for e30, e36 and e46 platforms. They are made out of 1.75x.095 DOM tubing and has 3/16" Mounting plates along with grade 8 hardware. I designed it so you can still run a rear seat, rear side panels and stock sunroof and headliner. I build these with custom harness bars as well as any other options you would like. As for me I have about 15 years of metal fabricating and welding experience and to date have sold well over 100 of these bars. This roll bar is top notch and I have not seen any other ones that are designed like mine. Please contact me at ben.sipson@gmail.com. If you send me your number I can call you as well if you have any more questions. I am located in Seminole, FL. I ship these for $150 to anywhere in the continental United States via Greyhound Package Express for $150 The bar fits any E36 CoupeSedan. Also make these for E46 Coupes and working on a E30 bar as well.
PRICE: $550 without rear x brace, $650 with rear X brace

That looks like it is all one piece. How much does it weigh?
Those welds look clean man. Good work
i wishhh i didnt daily drive my car
BUMP for a great guy.. spoke to Ben on the phone last night and he knows his product and competition and he has a great product and is willing to work with people on future roll bars.. I'm contemplating doing a rollbar from him!

How you get that in the car? Very well made.
Nice piece! Looks beefy.
You have to take out the rear seats, and side panels, front seats and the arm rest and ebrake. Its really not bad taking that stuff out. Then it fits right into place. Having a friend there would help. I put it in my car about ten times by myself.
And to clarify this meets all SCCA spces for roll cage tubing and design. It is 1.75 Outside Dimensions x .120 Wall Thickness DOM tubing. The rear mounting plates are contoured to fit the rear wheel arches and the floor plates are bent to match the contours of the floor.

Here are a couple pics of the plates. Sorry if the quality of the pics sucks. I took em real quick with my phone.

Hey guy, a bunch of you have emailed me & asked me what i thought about Ben's Roll bar design & i figured I'd list my unbiased impression here. (I don't know Ben & i am basing this impression off of his description & photos)
I go to the track a lot & I recently purchased a new TC Kline Bar that weighs in at 54lbs. In comparison to Ben's bar, the TC Kline bar is 20lbs lighter but it does not have the rear X brace that Ben's has.
Ben's design seems to be more rigid & should have more protection in a roll over or side impact. I think he has taken his design influence from more of a roll cage style.
The TC Kline Bar shipped from Denver to New England cost roughly $175 on top of the $595 purchase price, so Ben's bar is far more affordable.
The TC Kline bar & VSR1 bar both have a bend behind the drivers seat to accommodate a further back seating position. I'm 6'5 and this is good for a stock seat, but with a race seat, Ben's strait cross bar should leave plenty of room.
Ben's contoured Foot styles look correct.
The welds look clean in the Photo & his chose of metal thickness is the going requirement.
In closing, if I had not already bought the TC Kline Bar, I think Ben is offering a solid bar locally for a good price and i think i would have bought one.
Ben, you should think of a name for your company / Bar & put your name on your design. You might get a following and it will allow people down the road to research your equipment.
Also, perhaps offer a second lighter option for guys who are really weight conscious. 20lbs is a lot to some of us. (Especially when you gained 10lbs over the holiday)
Good Luck.

just an FYI, a bolt in roll bar is not going to meet any racing series rules. The tubing diameter would not matter in this regard.
If you wanted to build an E36 to meet the most classes, the majority of the cage design would be in 1.75 x .095. .120 wall is for smaller diameter tubing, in lighter cars.
GREAT design, and the contoured feet are a HUGE plus over some other designs, and I really like the fact that it is all one piece, with a X in the back to help reinforce the back downtubes.
Good luck, and in the future, if u can go to a 1.75 x .095 wall you would be better off, and lighter.
NASA time trials dont require a rollbar/cage, thus dont have any rule expectations for such, and can use any bar you want.
If you were to go to W2W, you wouldnt have a bolt in rollbar anyways, so this wouldnt even be part of the discussion in rules compliance.

In this picture, it appears you have another bend in the bottom of the main hoop. Is that correct? Or is the main hoop only bent on "one plane"?

Yes there are slight bends right about where the harness bar crosses. And I can absolutely make these out of 1.75 x.095 DOM if rules allow. It will save weight for sure. I just went with what TC Kline and Autopower used for their bars which is .120 DOM. I can also eliminate the rear X which will save weight. Also if anyone feels like they need bent harness bars for seat clearance I can do that as well.

Also I thought I would throw this in here. This is my 1969 Toyota FJ40 I am workin on. Just finished up tacking the cage together today. Might make some slight adjustments to it. I think I got a little out of hand with bending tube on this one

Maybe we are not talking about the same thing here. There are 4 total bends on the main hoop. 2 up top and 2 where the harness bar is located. Looks just like the pic of the bar you posted.

page 84
3. Main Hoop
A. The main roll cage hoop shall be as wide as the full width of the interior and must be as close to the roof as possible without violating the provisions of “Inspection” outlined below. One continuous length of roll bar tubing shall be used as the main hoop. The main hoop must consist of not more than four bends maximum, totaling 180 degrees +/- 10 degrees and in the same plane.
tubing specs
pg 87
3. 2501 to 3000 pounds
a. 1.500” x 0.120” DOM/Chromoly/Seamless
b. 1.750” x 0.095” DOM/Chromoly/Seamless
NASA rules are fairly close to these specs as well. With your rollbar being a fully welded single piece, it would be easy for someone to weld this into their car if ur plates meet the specs, and then all they have to do is add the front half of the cage.
That makes your option VERY enticing to future buyers
the 2 bends in the main hoop at the harness bar are on the same plane as the rest of the bar, or do those bends pull the main hoop bar forward/backward in the car?

Ok I see what your are saying. Its all on the same plane, no worries. Here is a pic that shows it better.

Ok guys so I have done some math and and have figured out weights for you.
1.75 x .120 DOM = Approx 75lbs
1.75 x .095 DOM = Approx 55lbs
Now some people have contacted me about removing the rear x brace and going with the two down instead. Here is a picture of what I would do if that were the case. So just imagine the X removed and the blue line a small support brace. This would weigh in around 48lbs if it was .095 and about 61lbs with .120

I am buying the revised 1.75 x .095 bar without the X bar in place. Basically how his new picture is, is what I will be getting. Instead of the Xbrace there will be a horizontal tube between the main hoop and both tubes connecting to the rear wheel well. I like this design for my application as it is lighter and still very strong.
