Cage Weights

[mcerbm]

Does anyone know the weight of the various cages offered for a normal narrow body imperial S3? 

Caged - Original superlight (double D) cage not compatible with windscreen - I have read 17kg?

Caged - roadsport rolled hoop (double D) is compatible with doors and windscreen - ? kg

Safety devices - roadsport - single diagonal (compatible with doors and windscreen - ?kg

thanks

I have a SD Roadsport cage single diagonal (albeit the tall version) and IIRC I weighed it to compare it with a tall single diagonal FIA bar including Petty strut.

Cage -12kg

FIA bar & Strut - 13.5kg

so 17kg for the superlight cage doesn't sound unreasonable....

Wow wasn’t expecting that. Is the cage thinner wall material for the pipes?

' Original superlight (double D) cage not compatible with windscreen '

My Cadged Superlite type Double D cage for my narrow body Live Axle S3 came in at 19.7Kgs ( with two head restraints )

The FIA bar has ~38mm diameter tubing whereas the cage tubing is only ~32mm. No idea on the relative wall thicknesses though.

I can see how it adds up quickly then with that difference in diameters

So so far its:

Caged - Original superlight (double D) cage not compatible with windscreen - 17kg-19kg

Caged - roadsport rolled hoop (double D) is compatible with doors and windscreen - ? kg

Safety devices - roadsport - single diagonal (compatible with doors and windscreen - 12kg

Anybody know the weight of the roadsport double d cage?
