This is a bit overdue (okay, long overdue) but I figured it's better late than never. If you're following me on Instagram or Facebook, you already know that I had to replace my clutch in 2018. It wasn't so much because the clutch failed. It was actually the clutch slave cylinder. Why would I need to replace the clutch if my slave cylinder went? Well, Ford had the genius idea of putting the slave cylinder inside the transmission. Ok, this isn't entirely fair. Putting my engineer hat on, I can see how this makes sense. If you put the slave cylinder in, it's outside of the elements and should theoretically last longer. Unfortunately, Ford should have invested in a better slave cylinder for this to be a great idea, not one that can't make it past 22,500 miles (36,000 kms), albeit with track use - which probably exacerbates the problem because of the additional heat and higher temps. But I digress. At any rate, the slave cylinder went. Most people would replace
BMW M2 equipped with an eLSD - BMW © A few weeks ago, I posted about traditional clutch-type limited slip diffs (LSD's) and how they work. You can read about those in the previous post: How Limited Slip Diffs Make You Faster on Track . But as you might know or have learned from reading the article, they aren't without their faults, which means engineers are always working to get around those limitations. You may not be surprised to learn that something like the Ferrari 488 GTB doesn't use a traditional limited slip diff, but it's not limited to super cars, far from it. Cars like the Golf GTI, the Civic Type R, various Mustangs, Corvettes, and BMW M cars, and even the Lexus RC F and GS F, all avoid a traditional limited slip diff in favour of one of these technologies. To keep things simple, I'll focus on two wheel drive vehicles. The vast (vast) majority of principles apply to all and 4 wheel drive vehicles, but there are some subtle differences that I'll
