this just gets my nipples hard thinking new tire physics is that much closer

in-progress snapshot. cooked the rears but so much fun to drive, i don't know if they can last with better driving.

will try to tweak but shouldn't suck like last iteration did sometimes

still not fast

at last. not quite tuned in the damping, but really controllable with throttle so steering wheel can compensate. stable enough mid-corner to allow to commit.

extended setup information in readme.txt to replicate exact feeling as much as possible (with G25/27). and a little demo where i fail badly but have fun

the zip is all the iterations i tried tonight on top of the 400 one that was the result of last session.

some fine tuning. not quite right yet but the most fun to drive of the bunch so far.

these last two are heavily influenced from a good xrt set (zeus bl1r) but some more work was added to get to this point so it's not like a total ripoff

um. needs fixing. the understeer is not from the springs i think but toe. just go slow and you will go fast (useful to hug apex even when entering the corner too narrow)

host settings:
g25 at 634

well, out of time before being satisfied with anything. however, just for interest here are two of about 30 iterations i worked on. posting since it may be a while until next time i get a chance to continue.

You're totally right about the ARBs. Most of the time I change things in the garage and go by feel to make iterations. When I loaded this last one up in VHPA I saw the roll stiffness was way too high (and the bump damp is over critical).

I think the reason is that overly lowering the car creates a longer roll moment arm and my idea was to keep the rears as flat as possible to help grip on the inside wheel. This was leading to more and more roll bar and some googling helped me start raising the car again and finding a more natural feel.

I ran across the interesting quote from Colin Chapman:
Any suspension, no matter how poorly designed, can be made to work reasonably well if you just stop it from moving.

of course the goal is to some day reach performance closer to that of WR setups, which is kinda far right now. It's a bit different though trying to make an all-around set. Things can feel great on one track and be horrible for a given corner of another track. It's a good challenge to compromise for south city chicane and aston gp.

I'm happy to get this criticism. i'm no engineer but i'm having fun and any feedback helps a lot. the latest version already has less stiffness and would be released but i'm trying for a minimum of quality assurance to prevent people from losing interest.

Hopefully i can post within a few hours since i have a break today

almost direct turn-in with a smoother transition to corner exit.

not endurance quality but very nimble and stable.

not there yet, but since i may not have the chance for a while, here are the latest iterations of what i hope will some day be an all-around set.

since i can't drive, this may be useful for others like me to have fun. there is a bit too much wing but the car stays very driveable and seeks to turn in while staying (sort of) stable through the mid corner and exit.

there are three sets, one from earlier today that stood out, another that i think might be the best of the three, and the last one i was working on tonight so maybe not as polished but quite interesting.

note 606 degrees with g27 in global profiler. it may need to be a bit lower still... not quite sure how to do steering geometry

Quote from edge3147 :

Quote from englishlord :

a jerky 30-40fps

So do you think when you go see a movie at a theater the movie is "jerky" because standard cinema frame rate is still 24 FPS

my head aches every time there is a pan. note that they avoid pans because the frame rate makes it so jerky

i had a go with R3s last night. it was a bit hard to get heat into them. i think R2 will be the final choice but there is a balance issue making the rears overheat.

at westhill i was able to do a lot of laps as long as i didn't push to max with a lot of gas. (rear left tire failed on inside on 39th lap (of 39 lol))

about ff i was totally off. i had been using 100% for a long time but recently put back some caster so i was at 35% and trying 40% now. oops.

this latest aims to improve mid-corner turn-in and possibly have the tires last longer by having less wear on inside.

i think it needs a bit more steering ratio. it's getting close to guidable in the middle of a skid with hot tires. it's never felt so much like a real car.

i'm so glad i got a comment i wonder if for faster tracks it's just straight wing that is the problem or if there is too much toe-in and softness in the tires? with this last set i'm finally sure the same times as my first all-around set can be reached

using these settings
wheel lock 639
force feedback max

a little better

i'd love to see Scawen's wishlist

+1 for your interesting list

my addition would be plasticity in the drivetrain

kinda sticks

pretty good

trying to go faster and sick of the understeer.

it feels too soft but i'm too soft to do the math. very fun but start with 100% fuel and try to make the tires last for max effect.

before i released my last all-around set i did 9 lap races of the entire lfs content (including rally) against a full grid of everything from gtr to gti, starting from the back. if i lost one race, i had to start over from blackwood. compulsive or just plain fun? well some people play bingo.

i didn't do as much testing with this one. any help is appreciated

note it needs high force feedback setting

i got two front seats out of a volvo s80 for $100. with a 12v converter to plug it into the wall the electric position adjustments work. having built a seat myself i can say having it be adjustable is a necessity for comfort.

are you getting force feedback from your wheel? is it g25/27?

Thank you Eric, Scawen, Victor. Your work, our pleasure!

ps all this talk of loops makes me think we could use a function to group objects, move them as a group and do save and load.

really nice. i love the little unfinished cylinder peg thing holding up the side mirror. unless you're looking to complain you don't even see it. they really spent the time on stuff that matters

fine tuning the last one

re adding programmers: it's not a programming problem, it's a math problem. actually coding physics simulation rules is simple, it's engineering them that's hard.
