How to Pass? (Page 1 of 2)

Umm... not sure what you are asking. I've been passed a lot in my Lemons "career." Most of that looked fine.

These endurance races have lots of opportunity if you are fast. Watch the traffic and pick the faster "lane."

If you aren't fast, advice on an internet forum is unlikely to make you so regardless of how fast your car could be.

That said, that looks like a good driver in a fast car. It looks to me that he is on the brakes later, and on the gas earlier, and doesn't hit anybody. The driver passed a lot of people because that car was fast, the driver passed a lot of people because they were slow drivers (as evidenced by the times when a drag race wasn't sufficient to execute the pass) in equally fast cars. "The Line" isn't always the fastest line in traffic.

If you want to get fast like that, you probably should have started competitive karting when you were 4.

Also, this.

Passing is about knowing your car, and knowing how to read traffic. You don't need a much faster car. I bet that car in your linked video isn't really all that much faster than the others, the driver is faster. And honestly you'll learn faster in a slow car because it makes you work at it more. If you know your car and know how it can take turns off line, you can get around people. But learning to read traffic is a skill that takes practice. (I am not saying I am amazingly good at either of these BTW).

The best passing and traffic practice I've ever found is showing up to the local go kart track and driving a bunch against the random arrive and drive people. You'll get a good mix of clueless beginners, average people who'll drive the line and force you to find another way around, and the local "pros" who'll make you work to keep up. Everyone's kart is more or less equal, so it makes you focus on reading traffic and improving your own driving to go faster. You don't drive a kart quite like you drive a car, so not all of it transfers 1:1, but the traffic reading sure does.

We run that track in Lemons and there is ample passing room there.  [ https://youtu.be/l_5aHCNeYso?t=128 ] I do a goodly amount of passing here too at the same track.  I don't force passes like the E30 was doing.  My mantra is always position over speed so you will see me give up overall speed and passing opportunities so that I can be where I want to be on the track.  I might give up a pass now to make a better/easier pass in a couple of turns.  At the 1:12:00 mark, me and the 700 car start cutting through traffic.  You can see the drastic difference in driving styles.

#1 identify how you are faster than the car you want to pass.   Can you carry more speed: under braking, through a turn, out of a turn, overall straight line speed. 
#2 get yourself close to the car you want to pass so that when you are faster than them, you can complete the pass.
#3 expect cars to do the unexpected and never assume that they see you.

Depends on how you define slow. A lower HP car that handles well in the hands of decent driver can be competitive. The Kim Jong Elantra is such a car. It handles well but maybe puts 125HP to the pavement. Maybe. We weigh about 2600# with fuel and driver. It is not a fast car. But we can hustle it through the corners well enough to pass a lot of faster cars. Especially on tracks where we spend a lot of time in the corners, like Sonoma.

I think your car handles well, too. So, if you are open to a suggestion, you might work on getting your corner speeds up before worrying about passing. I break each corner down into three sections: turn-in, apex, and exit and am constantly evaluating if I am as fast as I can be at each part of the corner. If you need to simplify that process, start with corner exit speed then move to apex speed and finally entry speed. Then start putting all three together.

Bolded text is basically the Lemons textbook for driving a quick(ish) car.

Faster is faster, doesn't mean just in a straight line.  Clearly though if you can blow by on a straight, that is the easy button.
Watching this video, you can't say the driver was just taking a faster line with a slower car.
He was taking slower lines but doing them faster!    Me thinks that is what made this car so fast and able to pass.
I had mentioned this before too,  he doesn't slow down much, keeps the speed up while passing.
Many (most?) let him by too.   I enjoyed watching it, was most impressive.

I would appreciate any links to good passing videos.

The last race we did with the Rolls was a learning experience.  I was passing anywhere from 5 to 20 cars every lap.

I've only raced a few times so take my info with a grain of salt. The Rolls being so huge makes things a little difficult compared to smaller cars like E30's zipping around everything. I don't like to be a jerk or force position or anything like that.  I would mostly pass by either powering around them when I could predict their line, or braking deep inside corners so I became visible and they knew I was there.

The most frustrating thing is when someone is unpredictable with sudden jerky movements. I notice those cars usually have traffic jams around them and take a little more time and patience to pass safely.

Yup, and that car isn't cheated up like many are in ChumpCar.

Wyatt is stupid fast in anything, that car without wyatt still pulls harder then many e30, put them together and it makes v8 cars wonder if they need a new tune.

Learn the other drivers and cars on track with you. Pay attention to how they drive and their capabilities. Use this when planning ahead with your moves as was mentioned before.

It will help you from getting caught stuck behind a slow car.

And then remember that every session there will be different drivers in each car so you'll have to re-learn the cars to a degree.

Here is Cerveza doing a lot of passing, seems pretty aggressive to me.
