Personally when it comes to safety I want a fully welded option that goes as far forward as possible and has as much side intrusion protection as possible. Especially pertinent if you are track racing.
I've attached three pictures of a cage I've had extended in my coupe, point to note is how the fitter has put the cage in past the screw fixings on the outside of the dash as far forward as possible with the base-plate welded on the front bulkhead.
I don't see how an off the shelf item like this can be made to fit so well - but that's my opinion. When it comes to safety how much is it worth?
Is there any chance of you posting up as many pics of your cage as possible? Once I get the MOT sorted it's full steam ahead with the cage for mine
I've got all my cage now, just needs measuring up, cutting and fitting. (Guna take a while) If I get one section in at a time i'll be happy but the motivation of seeing one fitted will help.
The b pillar is going to be fitted the same as yours but the a pillar section is going to be fitted on foot plates welded to the sill/floor pan so that it doesn't foul the dash and I don't have to go cutting, while being forward enough not to foul the inner door handle. In the rear i'm going to weld a solid tube in between the rear turrets; but haven't decided on where i'm going to fit the diagonal. Mostly interested in foot plates and diagonal fitment.
Cheers, Marcus.
