where can one find rollcage for 348 challenge ?
Those OE challenge cages are made from unknown metal ie dom or erw and what thickness? They no longer meet requirements for NASA or SCCA if that is your direction. They are also pretty heavy because they were bolt in. Also, early ones came without door bars and later ones did. The 355C and 348C cages are interchangeable. But if you want a fashion cage or be OEM then you gotta fine one of those cages. If you wanna be safe then you really need to weld in and do your research especially in modern door bar design. If you want more performance you want to weld in which makes a HUGE difference in chassis stiffness vs the bolt in OE cage. I ran both OE challenge no door bars and later custom 8 point welded.
Fatboy is right, finishing up a full cage this week. However, I have three of the OEM challenge cages I'll be putting up for sale if you need one. PM me.
