The in car footage of the 7:27 lap in news shows exactly the same style... So much for smooth driving... Seems incredible to get away with this on tarmac, I am not sure I am that violent on dirt...

the nurburgring is in some ways a bit unique though. for one thing the surface there is very bad which may contribute. and it has some unique types of corner too.

If you factor in the speed he is carrying on this run then it all looks pretty normal to me.He's not going down the shops or to pick up the kids,just how fast is 7 grand in 5th then about 6200 in 6.Think about it,at that speed it's all happening pretty quickly so the steering input has to match the speed.Watch any pro motor sport incar and its all the same.I think that incar is absolutely stunning and have a look at the time he achieved.And also notice how only at the infamously rough Karousel(spellcheck) and maybe two other times he moves his hand position on the wheel and has another grab at it.That driving style is why he does what he does for a living and we do what we do .

Having driven AWD soobies on tracks for the past 9 years I've found that an AWD requires a significantly different technique to RWD cars primarily because of the inherent bias towards understeer. Main differences Ive found are that in an AWD:

1. Trail braking can help get the back sliding on entrance to the corner helping the car point better towards the apex.

2. A "jerk" on the wheel sometimes has to be used to unsettle the rear end so that the car starts to slide allowing you to straighten the wheel and "drift" into the corner again helping it to take the pressure off the front tyres and allow it to turn in.

3. Oversteer can sometimes be corrected by actually putting the boot in and pulling the car straight. (Complete opposite of what youd do with a RWD)

4. A RWDs rear tyre slip angle can be controlled easily by putting more power on or removing it. This is not possible in Subarus, (especially the ones without the electronicdiff), but may be possible with the GT-Rs RWD bias.

5. U can use lift off oversteer tendencies as a tool in certain tight esses to help set the car up for subsequent sudden changes in direction. (Same principle as in 1 above).

haven't taken the R-35 out yet so Its a whole new learning curve....

haha I think duncan has come quite a way....including outright win in the NSW Supersprint champs 2009. Second outright in today's round too (behind a v8 radical lol) with a 1.41.08 which is super fast in a car with only light mods.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
