I’m looking to get a mk2.5 and really wanted an LSD on mine. I found a decent car that’s an 05 Icon. I’m not sure but it seems like these probably didn’t come with LSDs as standard? Either way, I wanted to find out without actually getting the rear axle up on stands. What are the physical differences between the open and LSD diff? I read somewhere that the LSD has those cooling fins on it, but then when I looked for the part itself that were up for sale, some of the open diffs also had fins so it’s not very clear.
