The author wrote that race cars usually don\u2019t have synchros, and thus require double-clutch for downshifting. Since the book was written in the \u201890s, I\u2019m wondering if it\u2019s still true for race cars nowadays?

Absolutely, heel and toe is, but there\u2019s no need to double-clutch. Having said that, knowing how to do it does help a driver understand the reason and timing for rev-matching. But it\u2019s not important.<\/p>\n<p>For anyone reading this who are not familiar with double-clutching, here\u2019s how it works: Approaching a corner where you have to downshift, you depress the clutch, move the shifter to neutral, let the clutch out, blip the throttle (rev the engine), depress the clutch again, move the shifter to the next lower gear, and then let the clutch out.<\/p>\n<p>This technique was needed when downshifting in old cars without synchromesh transmissions, so unless you\u2019re racing a vintage car, don\u2019t worry about it. Even if you\u2019re driving a car with a dog-ring (non-synchro) gearbox, don\u2019t use it. But you absolutely need to rev-match on the downshifts, which requires heel and toeing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Q: \u201cI\u2019m currently reading Skip Barber racing school\u2019s book \u201cGoing Faster\u201d and came to the chapter about shifting.
