If you want to do a proper skid then you need one of these! So I became an apprentice for the day to make my own Limited Slip Diff. If you’ve ever wondered what goes on inside the mystery box that makes your wheels spin, or you’ve just wanted to see someone send it with tools they probably shouldn’t be trusted with, this one’s for you. I'm the apprentice at a workshop for the day to do something I’ve never done before – build a diff. Yep, it’s my first time and luckily I had a proper mechanic on hand so I didn’t turn it into an expensive paperweight.
