Yeah, autoslolam, autocross, solo, whatever you call it; is mostly a social sport. With a lot of downtime for every minute of seat time you will meet a lot of people, and it is that aspect that draws a lot of the casual drivers.

Learning the course seems harder than it is. Take it in as sections, don't try to memorise each cone. In a clamshell there are only 2 cones that matter, same with a chicago box(aka 3 cone slolam), etc. The rest of the cones are just there to scare you. There are only so many elements that you can make out of a bunch of cones, so after a while you'll be able to relate sections you see to those you've driven in the past and apply the same techniques. Some elements even look like turns on a real track. When you walk, walk where you would be sitting in your car. Don't walk two feet left of a cone, because in the car you're going to be 5-6 feet off of it; that type of thing.

As with any novice on a track; the goal is to get a clean run in and build upon it. Speed will come with time. I'll try to wrap this up, but here's a bit of an advice dump. Turn your head on course. In the car, especially on a parking lot course, you may find yourself looking out the side windows a lot, or even over your shoulder in a tight turnaround. Turn the head far, look where you want the car to be. In a slolam look at the final cone, or at least 3 cones ahead if it is a long one. The slower speed the turn the more important it is to take the tighter line. The tight line is almost always the fastest, and as the day carries on you will find a lot of marbles offline anyway. Solo is a game of speed vs distance. Each turn you are deciding exactly how much speed to sacrifice to cut the distance. Shuffle steer. Try to not be replacing your hands on the wheel, or risk finding yourself crossed up. Leave the car in 2nd once you get there. Oh, and with a big rear bar you may experience some snap oversteer as you lift the inside rear tyre, so; be ready for that. Just go to maintenance throttle(mid-throttle) if that happens and it'll settle down in a moment.

If you see anyone emptying their washer or overflow bottle, do laugh.

Edit: oh yeah, brakes are for transferring weight, not slowing down. That too.
 
Thanks Marcus, good stuff. Seems like this could turn into a long conversation, rather than have the thread go way off-topic with something that some people might not care about, let's fire the social group back up and carry on over there. I've been wanting to make the social group more useful, this will help kick it off. 👍

Off Topic: Auto Cross
 
I'll be hopping in the room to run a few laps in a moment, and while I cannot commit to racing this evening I will perhaps try and pop in between tinkering with the car for this weekend.
 
I'm about to log in and join the lounge now. We'll start at Autumn Ring and go from there. If we get some people in the room we'll plan on doing a qualifying session and a longer race starting at 9:30pm EDT, perhaps a couple shorter races before then.

WIN. I am there.


BTW We are planning a Fast Times karting trip this late fall/winter. Anyone with in driving distance should consider making out for this LIVE ACTION. ;)

I will be on around 9:10ish, I'm testing an operating system.
 
I'm sorry I couldn't hang around to race last night, but it was fun to run a few laps with you guys regardless.
 
I have a question for the motorheads. I drive an Impreza, I have been driving with different brands of tires on the front and rear of the car for about six months without a problem. I had some bad luck with some vandals in my neighborhood and my front and rear driver side tires suddenly became deflated. I went to a tire place to ask if they would sell me 2 tires and put them on the old rims without installation, they told me that since I had a car with AWD they could not do this because the size of the different brands could affect my AWD and anti-lock brakes. I thought someone on here would know if that was a bs story or not, keep in mind that although the tires are different brands they are all the same size. So after all this rambling I want to know, can someone run the same size of different brand tires on an AWD car without it negatively affecting the car?
 
This issue is the circumference of the tyres. Very rarely are the same size of two different brands exactly the same. Much like you may wear a difference size shoe or pants depending on what brand manufactures them. Also, a pair of worn tyres will have a different circumference than new tyres of even the same model. When an AWD car has different tyres on different wheels it will cause the differentials to operate to compensate for the difference in speed between the wheels. Driving like this over a distance will prematurely wear the differentials.
 
I have a question for the motorheads.

If you bring your wheels into the tire store and ask to install two tires on those - they'll do it. You can even leave your car in the parking lot on two jacks ;)
All they care about is liability and money.
That said - any real AWD will be damaged from extended periods of driving on tires of different circumference. Subaru says maximum acceptable circumference difference is 1/4", which is about 1.5/32nds of thread depth. I forget which subie you have, but if it's 5-speed you'll cook solid your non-serviceable viscous coupling center diff. If it's an automatic, clutch-pack will wear out or a couple of solenoids in the tranny will die or both.

If it's an older 4eat tranny - those have a fuse to put them temporarily in FWD mode. I'd do that until I get 4 equal tires.
 
I'll support the info given. With AWD like ours you can't have the wheels spinning at different speeds for any appreciable amount of time or it will cook the differentials. That's why we have to be towed on a flatbed.
 
Are we doing a little preseason race Tuesday? Maybe Motegi east coarse?? Or whichever.... ??
 
^ Yes, we're going to give the new update a good testing tomorrow so everyone make sure to download it earlier in the evening. I should have the lounge open around 7pm EDT and we'll just go from there. I don't know what's going to be in the update so I'm not going to plan anything firm, just lots of testing.

In off-topic news, I enjoyed my first AutoX yesterday and finished 2nd in my class (out of 4), just 1 second off the leader. Getting through the course is kinda difficult and confusing, I didn't have a "good" run until my fourth go, and that ended up being the final run.

Here's a vid of my fourth and final run. I'll go into more detail HERE.

Nice! 👍
 
Gonna try to hit the lounge for a few laps around the GVE-R so that I have something to compare post-update.
 
Update is now available...
 
Well, I ran 17 laps before/after the update.
Post-update wear:

Pre-update wear

Looks like maybe 25-30% less wear.

Overall best time was about the same (and still 3 tenth slower than Marcus's, and all in T1, gotta figure out wth he's doing in turns 1&2), but post-update I ran all 17 laps within a few tenths of my best, where prior to update times crept into 0.5-0.7sec+ slower territory but the end of the stint.

Sooo, seems like voluntary tire strategy is out.
 
Interesting. I guess this will make a no-stopper more feasible but I hope it doesn't eliminate pitstops altogether. Probably will though. 👎

If anybody else has time to do some testing of the new update please post any findings relevant to our season here. I'll be at work for the next 9-10 hours so I won't be able to check anything out until tonight. I've read some of the early reports and besides tire wear I haven't seen anything that would have much impact on us. My main concern is whether or not our qualifying procedure will still work properly, as long as that still works the same then we should be ok.

DSG, which track were you running for your tire test? HSR?
 
Based on what I've read I expect less tire wear as DSG has already tested. Also, slightly more downforce effect, and slightly lower top speed but probably not enough to have a dramatic effect on the Nissan. Guys are back to getting 30 laps on softs with Nascars on Daytona. Downforce has a bigger effect on top end speeds now but there isn't much downforce or HP in the Nissan, in my opinion, to have much effect. Not sure how it affects lateral grip, if at all.

Since we won't be adjusting downforce (no tuning) I don't think this will have any real effect on us. It may slightly change how the car handles, but as you said probably not enough to make any real difference. From what I've seen the "stock" setting doesn't appear to be making any change to the car, it's more that when you make a positive or negative change the effects are greater.
 
Alright folks. I, as well ran a few laps just before and then again after the update. I only ran 4-5 laps including my outlap each session, so I cannot comment much on the tyre wear. I did not notice much difference in the wear during my few laps, but I was also abusing the car in 'qualifying' type attacking. This was all on GVE/R, in the ORCA lounge, with proper regulations.

My PB from last week was a 1'07.562.
My best of 4 laps before the update with dsg was a 1'07.742.
My best of 4 laps with a good buzz at 1:45AM after the update was a 1'07.693.

These lap times on this particular combination accumulates to noise to me, BUT, the car has changed. The car feels more stable, but it is not pushier. I think this is because the source of these changes is different. It feels more stable I think because the rears are not losing grip as quickly with the increased wear, allowing a bit more throttle abuse. It doesn't seem to increase push, however, due to what I expect is the increased effect of the downforce. The car's factory settings are not at min downforce, and the changes are not linear. The nose is more planted at speed. The car is overall 'easier' to drive, I feel.

Now, you guys are probably thinking along the lines of 'how the ^#!( is the car not producing considerably faster lap times if what you say is true.' I think that is a factor of the test course. The increased downforce certainly allows more aggressive entries, higher minimum corner speeds, and higher exits, no question. On the final turn in GVE/R it is worth 2-4 mph depending on how you tiptoe along that edge. However, this is largely counteracted by the increased drag of the aero. I did notice coming onto the main straight with a larger head of steam, by a couple of hundred rpm at least, but then after the start/finish line the car does not pull quite as hard as it did previously. In fact, I'm starting my turn-in to T1 LH bend at 1-2mph lower than with the previous laps before the update.

All of this said, I do think the update ultimately has lowered the target time with a bit more seat time to adjust to the different characteristics to capitalise upon. Before the car was a 'trail the snot out of the entry, tiptoe the tip-in, and crank the wheel to scrub the fronts to make it push a little on exit, putting the power down' type of approach. Now it is more of a 'hammer down' affair everywhere.

Again, while the car's potential lap times I feel have dropped slightly, I think the changes will tighten the field a bit. Being that the car is much easier to drive; more forgiving, I think the folks in the middle of the pack will benefit the most from what is essentially a reduced penalty for mistakes and overdriving. I think most people will find the car 'faster' for their abilities, and certainly find more consistency in the behaviour.

I, as well, will not be able to drive again until later on this evening, but these are my initial impressions. More may come to me as the day passes.

^ Well, I'm not good enough to pick-up such nuances, but I can confirm that the car? on average, is easier to drive after the update. I'm not sure it's the change in the tire model or simply fresher tires
 
Lol, one more thing to check (or decide on) then.
Run qualifying with 'collision off' to disable draft (if so - check if enabling collision preserves qualifying order)?
Or run quali with draft? I'm sure that'd be 'interesting', especially @Monza.
 
I am not a fan of qualifying with the draft.

With collision disabled fast guys can drive on through any slower traffic. No more ruined qualifying runs.

Think solo track run for qualifying. However everyone gets to be on track doing their solo runs.
 
Still not sure what collision disable is all about? Is it basically like having penalties on but with out the penalties?? Where you drive through the invisible people? Sorry, but just a lil confused.

Problem with that........what happens when I forget to turn collisions back on for the race? We'd have to abort, do a manual grid line up and restart. That's presuming collisions can be turned off during free run.

Collision disable turns everyone into a ghost other than you of course, so you can drive through someone and not interfere with them, or they you obviously. With collisons disabled there is no draft effect. With collisions ON, they way we've always done it, you'll have drafting in qualifying, you have to pick one or the other. There is no mix and match option.
