Can anyone confirm the rear diffs in the jag IRS are all interchangeable?
I've got a 2.88 in my IRS at the moment. My engine and box I'm running originally came with a 3.62 rear end. I'm concerned its not gonna do a burnout etc because of the 2.88 so thinking of changing it out now before final paint and assembly.
Also can anyone confirm that 3.31 is the highest ratio available?
