E93 roll cage?

tlr · 03-05-2011, 09:58 PM

What's the feasibility of putting a roll cage in an E93 for taking to the track? Has anyone done this? Especially interested in one that can easily be removed.

+1 on this

if mounted structurally sound, maybe we could ditch the steel braces underneath?
Could lighten the car up a bit

you would atleast need a full cage before you can pull out the steel braces

I'm just curious, why wouldn't you start with a coupe or sedan to convert to a track only car?

koxal · 11-14-2012, 01:01 PM

it is not feasible to track a convertible car because of its extra weight...
i am not saying you cant but not ideal...

THE TECH · 11-14-2012, 01:56 PM

Just have a fab shop make one.

If we had a convertible locally we could test fit our cage

The track can't handle it?

Seriously though, I realize it won't be competitive with E92s etc, but that doesn't mean I can't have fun and compete against myself.

With the thickness of the hard top, I think you would have to keep the roof down permanently or you would not be able to pass the broomstick test.

Forgive me if you're not new to all this, but you do realize you shouldn't be driving a car with a cage without a helmet right? If you are saying cage but mean roll bar or half cage, then see first paragraph.

I feel like I missed something here. Where does the helmet comment fit in?

bigjae1976 · 11-28-2012, 10:16 AM

I think this makes about as much sense as the helicopter ejector seat.

So you put a cage in your car that you take in and out before and after every event?

Sounds to me that OP wants to put a cage in a car and then take it to the track. That part makes sense, but I don't think he understands that you shouldn't be driving a caged car on the streets....without a helmet.

So OP...enlighten us...are you planning to make you convertible an off-road only car to be for track only?

Some people race Spec E30's with welded cages, but I doubt you want to weld a cage into your convertible. Install/removal is really a pain of even a bolt in bar/cage.

Our customers car, he no longer has the top

Porschefile · 11-28-2012, 03:06 PM

Just get a coupe. Coupe is lighter, more rigid, and has better aerodynamics. If you're hardcore enough to warrant a cage you'd be well advised to put down a few thousand bucks (or possibly even trade straight up) for a better suited car for your purposes.

The last post shows that it is possible! And he even stripped the back!

Honestly I don't think you will ever want to remove and reinstall a cage. You could go the route of an add-in roll bar. I know they make one for the E90 and E92 (E93 no idea) so you can run racing seats and a harness without a cage. They also are somewhat removable if you only do a few events per year.

Better off staying with factory engineered safety.

Porschefile · 11-30-2012, 02:02 PM

Looks like the E93 bar shown is Autopower.
