Focus RS at the Nov 2017 BAC Rallycross - Kevin Doubleday © If you've read my last post - The Ram's Eye is going Rallycross - you already know that I'm starting rallycross this season for the first time. I started high performance driving 7 years ago in 2011 but have never strayed away from tarmac/asphalt. Living in Canada - which rightfully earns the name 'The Great White North' - means that I had to suffer serious speed withdrawals during the track off-season; that typically lasts from the middle of October to the middle of May. But there is a treatment for people with my condition and it has been available locally for nearly 20 years. I went to my first event this past Sunday and spoke to a few of the seasoned rallycross veterans. I was told that local speed freaks started organizing rallycross events for that very reason around 1999; to get their speed fix during the winter. It took off a few years later around the 2001-2002 winter season and nobody loo

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
