This is not a question about a recommendation about different manufacturers of LSD units, already done that, but more whether it's worth having one at all. I am about to replace the clutch and flywheel, and I am struggling over the decision on fitting an LSD at the same time. I understand the overall benefits of an LSD, but really wonder if my own usage warrants the significant additional expense. I have an 04MCS with 45K miles on it. It's my daily driver. Apart from a couple of trips over to the West coast, my general trips are short and local. I have driven on a track once in the 6 years of ownership. While I certainly drive 'quickly' around the local roads, and really enjoy 'throwing' it around, I still really wonder if I will really get the full benefit of the LSD. Since February I have been running 250 WHP. Help!
