Default Double Clutch

Diveganesh, started a threat about an instructor telling him not to heel toe his turbo, blah, blah, blah. The thread went to the mechanical benefits of heel toe, matching revs, etc.

However, if you really want to save your transmission, double clutching is the way to go. How many racers, DE'ers, track addicts double clutch for your downshifts?

Waste of time and effort on a somewhat "modern" synchro transmission in my opinion. I'm a big believer in removing complications where you can. Good skill to have in your bag for driving vintage and dog box transmissions though, or for fighting a dying transmission. And in the case of a dog box, you're probably checking and replacing parts on a regular maintenance cycle anyway...in many cases, using the clutch at all is a waste of time/energy.

My answer: Everyone should know how to do it, but it's not something you should bother using in every car.

In a modern syncro car, I don't. When I drive older cars and the like, yes.

You realize that you're channeling GhettoRacer, right ?

Never once. My feet are too slow. I do heel & toe all the time. In fact I use to skip gears going down, but have been hitting them all at Miller Nationals. Seemed to be more stable and better to get in the car in gear smoothly.

It certainly helps with not only keeping some drag on the rear wheels to create stability under braking, but also it prevents you from needing to make one HUGE blip at the end of the braking zone when trying to blip up the revs from 5th to 2nd gear, etc.

Even though the Ghetto was before my time, I've gotta be honest. That stung a little.

I have been trying for years to master that skill with sequential boxes, but just can't get the hang of it.

Dennis does a great job here with a 928, but Im still really puzzled as to why bothering to do so. For me, the 928 gear box is pretty cumbersome anyway, I would probably break the thing in one lap, If I tried to do it.

If you really try hard you might be able to do it. You just have to have a REALLY bad one the previous time through that part of the gear stack.
