Default Rear roll cage

Most likely going to custom-order, but I want to make it look like this:



Since it's my first time with roll cages, does anyone have any idea what materials/structure are commonly used in E36s?

He has made a lot of bars, but is far from Japan. You can also try Autopower and Kirk, but some of their models are 3 or 4 piece rather than fully welded and the bar you pictured is fully welded. They may have fully welded options as well. The rear X is also an option in bar design. And bolt in versus weld in is also an option in bar design.

Due to shipping costs for a fully welded bar, you might be best off having one made locally assuming there are shops there that do this work.

The paint is something you can DIY or have powdercoated.

Just the roll cage part.I suspect the alcantara flooring would cause more trouble when I have to replace my fuel pump; I would remove my rear seats as well.

If your going to add a cage I would suggest adding proper density padding and not pool noodles.

Cages in street cars are kind of counter productive IMO.

I completely agree with you, which is why I'm looking for bolt ins rather than weld in because I'll only be using these when I autox/track the car. I just want more rigidity in the rear during high speed cornering.

A bit of a pain to install and remove so maybe not the part to change in and out for occasional driving events. If just looking for rigidity consider the Mason engineering front and rear braces.

Not only that it's a new place for water to get inside your interior and start rusting. Not the road you want to head down.

Looking at X brace closely for now.

I do have front (OEM GT motorsport ) and rear (ARC) tower braces, but these don't seem to do much.

I have the front x brace and it makes a good difference with the turn in.
