Yes, I am finally at the point where I am fast enough requiring a roll cage. It's better to live through a crash than maimed especially this track thing is just a hobby. I like the idea of OEM roll cage since it's not permanently welded but how safe is it compare with a fully welded cage? Race approved?

Oakley's full carbon fiber roll cage is another interesting idea ...

 

Thought Oakley was out of business, or otherwise in the weeds ?

 

I think you mean the oem roll bar system as it is not really a cage since it has no side impact protection....the first thing you want to check is to see if your RS has the front mounting plates for a cage...if not they will have to be welded in...I really think a call to James Safronas or Fabryce at GMG will put your mind at ease...find out what protection they are using in their WC cars and consider that...

 

?? no idea. That will be a shame if they went under

 

The only OEM rollcage is the Clubsport cage (front and rear sections) which requires the floor plates to be welded or bolted in place... unless your lucky enough to have one of the early cars which already had the plates mounted from the factory. However, the Clubsport cage doesn't include side impact bars. Otherwise you have the OEM Techquipment bar which is strictly a bolt in affair for the rear part of the car only. Those are the only OEM options and they are special order from Europe only. There are aftermarket options, but any full cage is going to require some welding or drilling of the tub.

 

Same here, I thought after the Farnbacher-Lole debacle Oakley was in the weeds?
Anyway that Oakley rollcage seems weird because there's no crossbar between the C-pillars which I would think is an integral part of structural rigidity. Plus where do you fasten your shoulder harnasses? I hate that
**** of attaching them to the floor of the tube behind you.
Bottomline I don't like it. I think it also cost = to one of your ********* if I remember.

The newest OEM roll cage has door bars as shown below but it does not have the cross beam knee bar between A-pillar to protect you in case of side impact



Cross knee bar is something SCCA require as far as roll cage goes
Here is one P-car without knee bar and look at how far the driver side A-pillar got pushed in with side impact. strong door bars is very important too



Here is a 964 with knee bar above the steering column

 

Interesting:


Now how does the dash and instrument cluster figure in with this bar set up?
Never seen it this high but normally below the dash between the A-pillar bars.
When you get this far it ceases to be a street car.

When you add a cage at all, it ceases to be a street car. A full cage is very dangerous on the street.

 

Considering that bolt-on is the only way for aluminum framed/tubbed cars to attach a roll cage, it should be of equivalent safety or nearly so. However most SCCA classes require a welded in roll cage unless the frame is aluminum. Wherever you're planning to race may have different rules but SCCA is a good guideline.
