GTM roll cage modifications and race car build log

[kabacj]

Normally X-design are stronger for cage purpose. If you don't have that extra room that the gutted doors would provide, than X-design provide similar protection without being as intrusive. As well as X door are cheaper than others.

Hi Frank. I agree an x in the door opening would be stronger. That was my origional idea. However I could not make it work without making entry and exit very dificult. Since the GTM is quite low and your knees are almost at the leading edge of the door entry and exit are already tight. I wanted to maintain ease of entry and exit so I went with NASCAR style. Since the frame structure is inboard of the fiberglass shell
gutting the doors does not buy you room like it does in a production car. Thanks for the input. If someone can make the x style work in a GTM I agree it would be better.
