I would love an LSD, but I don't think I can justify the price.
However, I can't say that I've ever been in a 335d which has one, so I'm unable to compare the gains for the money.
For me, my thinking is:
- £300/£350 for a remap
- £2k for an LSD
Which one would my car gain the most from? I guess if I had the money I would most likely do both..
