Roll Cage

I will probably be turning my E46 Sedan into a track car for Road Course, and thus will need a cage to run in the series I am looking at. I plan on building most of the cage myself, however does anyone know of a place that will bend the hoop/roll bar. That is the only piece that I do not feel comfortable doing myself.

My cage came from Kirk Racing. You could possibly contact them and see if they can provide you with a main hoop.

Are you going racing or doing HPDE's? If you are doing DE's I would suggest picking up a rollbar from Kirk. They make a great product. It's already painted and they fit really well. Just bolt it in and you're set. It is probably cheaper to get the whole thing from them once you consider the amount of time it will take for you to build it yourself. If you are going racing I would suggest taking it to a professional cage builder.

Taylor, I will be racing but cannot afford the $5K bill that a few shops have quoted me for the cage. I own a welder and have access to band saws and many other fab tools so building a cage would not be difficult, just time consuming. When I am not in school during the summer and have evenings open. It makes sense to do something constructive.

I hear ya. $5k sounds extremely high though. If you have the interior stripped and ready I wouldn't expect the bill to be more the $2k for a basic 6 pt cage unpainted. Not talking chrome moly here just a solid basic cage. Depending on the class you're shooting for you may get more elaborate with tie in points and whatnot but $5k seems like a lot. This is my cage. Very basic as my class limits tie in points but I added nascar bars and foot protection. Cost me $2300 unpainted. Make sure you do everything you want to do on the interior before the cage is installed. Good luck. It's always nice to see someone else hitting the track!

That looks great. What is the advantage of NASCAR Bars rather than standard door bars? I talked to a guy at Kirk Racing, and I was debating doing the standard door bar with an additional bolt in bar. I do not plan on driving the car on the street often when it has the cage, but I may keep it licensed.

I personally wanted a modified x (an x that bulges out into the door like the NASCAR bars) instead of the NASCAR bars but my builder wanted to do them so I went along with it. They offer a lot of protection and are far away from me so I'm happy; that's the real advantage. Cage on the street isn't so good if you get in a wreck but if it is only drive it on occasion you should be okay. Keep us posted as you go along. Good luck!

The LeMons crew likes http://www.rollcagecomponents.com for budget cage parts and kits.

Make sure the material is DOM and not ERW. Most of the cheap kits use lesser material. SCCA/NASA do not not allow ERW for roll bars.

If you are just doing track days it will be ok but f you sell the car later you will be limiting yourself to potential buys.

Also these kits do not allow for any interior except for the Dash.

What bender do you have? I may be able to help you out.

I have not purchased a Bender yet. I was going to get a cheap manual one though.

Pipe benders, a.k.a. tubing denters, are prone to crimping or dimpling the tubing which results in a failure at tech inspection. Rotary draw benders (Pro Tools, JD Squared, etc) eliminate tubing collapse and provide consistent shrink/stretch when bending.


I use a Pro-Tools 105HD bender and a Pro-Tools Racer notcher. I made the hydraulic conversion with an engine hoist cylinder from Harbor Freight and the stand from a scrap tool stand.
