Wanted mk indy roll cage

Being realistic I can't see you finding one,unless of course someone writes off there car and is willing to cut out the cage!
99% are welded in when the chassis is in the build stage ,and even ones that are added pre-build by MK are fully welded onto chassis.

Try this guy - Tube Bender

He made a custom one in kit form for me

I have a brand new Indy rr cage, it is cuttently set up for removable back stays. Removed from race car as its not compliant with ROPS regulations.
I am in south east, let me know if you are interested

Mines an older indy so doubt it will fit unfortunately

Not dealt with MK myself for many years, but is it not worth asking them? They can probably make one to fit and guide on any chassis mods required for fitting.

To be fair i managed to get an Indy R cage on here second hand but I was very lucky as it came from a damaged car and it was reasonably local to me

have a look for a Westfield cage, they come up on eBay quite often they fit with just a small amount of fab work and they're 'outside' the car so they dont take up leg room like the MK one does
