Roll Cages vs. Roll Bars in higher class cars

And, yes I did asked about it. Why have a cage and don't want to use the net? Just prefer to not screw with it. If I want to put the car in a class where a cage is required, I have it, and the net, multi/layer fire suit, neck collar, and gloves.

Ed;
Don't nets have a cert, expiration date? If so then the net that you have in case you "want to put the car in a class where a cage is required" may be out of cert. at that time..... ;-]

Only mesh type nets have to be replaced every two years.
The more common ribbon type does not need to be replaced .
The rule book states window nets are required on all cars REQUIRED to have a cage.
This may vary by Division or track,but in so far in D1 cars that have a cage ,but are NOT REQUIRED to have one, have been alowed to run without using a net.
I have several customers that have told me this is the case.

Also rocker sill bars are still not required on non SFI spec roll cages [8.50 and slower et] on cars with stock floor pans and dont have more than 6sq ft of removable floor for trans removal.
I,d still recomend one ,but the rocker and the dash bar are not required if the floor and rocker is not modified.

The only way to build a cage is to WELD 360 DEGREES and use gussetts.

Chrome Moly will rust just as much as mild steel ,once the mill finish is sanded off for painting ,if left exposed.

I put a full cage in when I built the stocker just for my safety even though it was not required. . I would not have it any other way with the speeds of the new Stockers. It is also nice to have if you ever want to run Superstock.
