I mean purely drifting, ignoring road use at all. I'm no drift superstar but I've owned 3 cars with 2 ways (still own one of em) and shitloads now with welders, and TBH, I prefer the welder, or at least find zero advantage of a 2way. One of my cars has a Torsen in now too, which lots of people seem to prefer even for drifting over a welder, but fuck no, I hate it in comparison. Some people who ARE drift superstars seem to run fully locked diffs though. Eric O Sullivan (Ie Formula Drift, Prodrift, Drift Allstars, etc) for example said the other day about locked diffs on here... "less shit to break and always feels the same no matter how the car is loaded up. I don't know why more people in the drift world don't use them, other than backwards entry attempts I've never felt the necessity for a diff" BonBon has pretty much always that I remember just ran a welder on his cars. The DW AE86 now runs a fully locked diff. I bet a shitload more top comp cars, esp Formula D ones, run spools compared to what people think. I've always prefered a welder for drifting purely as I know exactly what it's gonna do at all times, and what it's doing is what I want it to do. So, for drifting, what's the genuine advantages of a 2way etc, as I've never felt it.
