I'm coming from an 88 911 where double clutching was required for second as well as first.

The S2000 doesn't seem to need it for any gear but first, though the transition is a lot smoother especialy when dropping to second at 40mph.

I was surprised how smooth the transition was when double clutching from second to first at 15mph. Most cars are much harder to do this.

Do it all the time also. usually below 10 mph rolling to a stop. I did it successfully at 31 mph just to see if I can, and it worked just fine.

 

mind me for asking but whats double clutch?

 

Hi S2KGuy

Double Clutching means first shifting into neutral and then into the gear of choice. So, from 2nd to 1st, you'd shift from second into neutral, release the clutch, depress the clutch, match revs and shift into first.

 

Double clutching into first from second is really not necessary and in fact can cause some wear like mentioned above. Sorry but, it's really better and more effective to use the brakes from that point on. Weigh which one costs more to replace, I will opt not to do it at all.

 

Hi Takashi

I agree, but double clutching is not usually used for simultaneous braking and downshifting. I only use it when downshifting into 1st for extremely aggressive driving.

 

I can do a regular heel and toe downshift from 2nd to 1st without double clutching. Both my street car and race car can do it. No problems or grind. It's essential to match the revs or be a little more aggressive on the brakes before the downshift.

 

Here's what I do.

In a 2-1 shift you would (as you stated) shift to neutral, re-engage the clutch (all the way up) match rpm for expected gear, and immediately disengage clutch (all the way down) put it into first and re-engage the clutch.

I find it a little difficult to jam it into first by just heel toeing it, without double clutching it first. Not matching revs at all and just using the clutch produces rather unstable handling, though it is easier.

As far as it not being necesary, that is correct. But it is more fluid, more fun (for me) and promotes more stable handling during aggressive driving.

Being that this car has such long legs and the power band is high up you do a lot of down-shifting.

I learned down-shifting by double clutching and I have a hard time not doing it.

i do not double-clutch, but do "blip" (hit the accelerator) when downshifting to raise the rpms.
good idea to match the rpms, but imo not necessary to double clutch...
