So I'v been looking into build specifics/budget for a future Cobra build and was wondering - is it possible to upgrade to IRS after the fact (e.g., after the car has been completed)?

Right now it looks like the financial hit for IRS is just a bit too far out of my league to include IRS in the initial build and straight axle is the way I am leaning. With that said, I always like to know what doors I'm closing that can't be opened at a later date.

I wasn't sure if the frame itself is made differently to accept IRS or if was something you can always bolt on later (even though I suspect it would be very difficult).

Any insight is always appreciated.
