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 ...
I'm finishing up a comparison post (link to introduction: Intro: Focus RS vs Golf R vs WRX STI vs Evo X ) and, throughout the post, I realized that I have to go off topic a lot to talk about how each type of differential changes the way the car drives. As a result, I thought I'd write a separate post to go into more detail before I post the comparison to keep it more focused on the cars and avoid veering off topic too much. By saying "Limited Slip Differentials" in the title, I am including torque vectoring diffs because, although current conventional terminology treats them differently, a torque vectoring differential is, in essence, a very sophisticated limited slip diff (LSD) that can be manipulated to actively help the car handle better. And while none of the cars in the comparison use open (without help from the brakes) or non-gear mechanical LSD’s, I’ll briefly discuss them so that the post is more inclusive. I’ll only focus on using power to help the...
