The community 288GTO is very, very good but I've no doubt it'll still be heavily tweaked by Kunos before it gets to production. The same thing happened to the 787b; the one in the game now is very different to the original, community car.

Going from what I see on public servers, cars that aren't popular are classic cars, F1 cars and supercars. Even the modern hybrid Ferrari F1 car that is already in the game doesn't seem to get much use.
So that leaves Endurance racers?
Just about. Most of the populated public servers are GT3s, GT2s, the formula Arbarth and occasionally GT86. Everything else gets 2-3 people who leave after five minutes. 90% of the content goes unused.

There may be other reasons for that in the online racing world. I can only speak for myself, but my favourite cars are the Ferrari 312, Lotus 49, Maserati 250F 6cyl, Lotus Exos and 911 RSR. I've spoken to many others with overlap in that list. I also drive the F/Abarth a lot because it's very similar to the car I race in real life and is good for practise.

I wish I had the time and skills, as I have a racing car sat in my garage that I could presumably model perfectly as I have all the dimensions, weights, torque/power curves etc. It would also be of great benefit to me to practise with it on a sim as I can't afford to drive it anywhere near as often as the people I race against.
What car is it btw?

Edit* Just seen its a 2008 Formula Renault 2.0... amazing, Daniel Ricciardo and Valtteri Bottas both competed in those in 2008. Some great champions in the series too, Kamui Kobayashi, Robin Frijns, Carlos Sainz Jr, Stoffel Vandoorne, Daniil Kvyat, Pierre Gasly, Lando Norris and more!

I'd be willing to recreate this for you, but unfortunately these days I'm very busy and really can only take on paid jobs - if this is something that still interests you let me know, as there is a lot of potential to create something very high quality with real data.

Example of the project I'm working on at the moment (FSAE car for a university):

Thanks. Money's tight at the moment as the engine blew at Silverstone last week, but I'll bear that in mind. When we get proper internet at home I look forward to getting iRacing with the FR2.0 which they have already (and the FA in AC is fairly close), but the more immediate interest to me is the spec I have to run my car in for UK circuit racing: air restrictor to limit power and ride height jacked up to 40mm - this is very different to standard spec, and setup in particular is really hard because I can't rely on the data and setups I inherited with the car.

Whist we're on the subject, the other thing that annoys me about sims is that they claim to model cars accurately, but the setup options are usually not representative of real life. For example, the FR 2.0 and FA both run a 'monoshock' front suspension unit, which runs a conventional spring and damper for pitch, and a stack of bellville washers for roll, which give a number of pre-set roll stiffnesses, with no damping in roll. AC don't model this, so you adjust it like a conventional F3/F3000 with a spring and damper on each side connected to a pushrod for both roll and pitch. Another example is the 2-Eleven that I owned before the FR 2.0, and that too had different adjustment options in real life to on the sim.

No problem, give me a shout if you ever fancy it, as I love working with real accurate data for projects.

Whilst I don't claim to understand all of what you are saying, I think it is possible to separate pitch and roll in AC by using a third spring - is that what the FR 2.0 uses or is it something different? In that situation you can run a damped third spring, and undamped normal springs for roll.

Will do! I can let you have full access to the car, along with data.

The Monoshock is different to that. I can't access online photos from work, so I'll have to try and describe it with words: A monoshock unit, as used by the FR 2.0 and FA at the front of the car, uses standard pushrods as with any other single seater. As you no doubt know, normally, each pushrod connects directly to a bell crank to act on a spring and damper unit - one at each corner of the car. In the monoshock, both front pushrods connect to a single component which pivots back and forth if the pushrods push in/up or out/down together (i.e. a pitch movement of acceleration, braking, or bumps), and this pivoting is controlled conventionally by a spring and damper. However, any movement in cornering, i.e. which causes one pushrod to push and the other to pull, causes the component to slide sideways left and right along a bar - it slides right for right hand bends (left pushrod pushes, right one pulls) and left for left hand bends. Inside the component is trapped a stack of dome shaped sprung washers ('Belleville washers') which resist this sideways movement. The washers can be assembled in various orientations, providing different spring rates for roll. The washers are trapped in the component by a moveable collar which provides preload up against the washers. No damping is present in this roll system, so it is only suited to a single seater, which has very little roll inertia. A monoshock system saves weight, complexity and cost.

Nice explanation, certainly paints a clear picture in my head of the system, sounds like a great way to go about things in smaller single seaters.

Would similar behaviour not be simulated with relative accuracy just by removing/reducing the damping on the corners with the springs acting as the washers, whilst still keeping the heave spring as normal?

Yes, but it would be nice to see the actual settings modelled so I could try things out for real life racing. The range of springs available and the gaps between them is also different. Likewise for the 2-Eleven. It would also be nice to have it to give me confidence that the models are actually realistic.

Perhaps wasn't the best idea to drive the Maserati 250F after I had been driving F1 cars as my braking points were messed up but I wanted the best reflections/on board camera view to see the full effect of the lights and reflections on the Singapore Night edition track.

https://www.youtube.com/watch?v=vhSLKlmDUXU

Managed to capture sound as it had never seemed to work before on Shadowplay properly (stereo mix enabled but unavailable!?!?!) after much gnashing of teeth and head scratching, basically turning it on & off again, selecting, deselecting, disabling, enabling and trying older VIA audio drivers whilst keeping an eye on the audio mixer levels playing a long sound file and waiting until it moves then quickly run the replay and capture it.

Track (includes night version of Bahrain too) - http://www.simracersjapan.jp/nightpack.rar select the night weather on the track options page, just below the time of day setting.

Who needs the Ferrari pack when you can just make your own! tongue out










To be fair the 550 Maranello isn't due anytime soon, its the 550 GTS racecar that is more pertinant (together with 5 other mid-2000s GT1 cars!).

Kudos for that, looks good. I really don't have the artistic flair or IT skills to do that kind of stuff, it must be really cool to be able to do it and see the results of your work.

Bought this game about 2 weeks ago and a controller (gamepad). It's quite tough with the controller but every time I play, it feels like a real indulgence.

I bought a ps4 last week and should have assetto corsa arriving tomorrow. Think ill be getting the season pass pretty early on. And looking forward to trying it my little set up - t300rs wheel, t3pa pedals mounted on a playseat challenge. Spent half an hour setting it up today and sitting in it pretending to drive!

You will love it, get the Porsche pack - the GT3RS is sublime!
