Clue me in on the Porsches, please

    [Singleplayer:] I now know that the Porsches cannot be entered in sprint races. I guess the workaround would be to drive them in a custom race weekend event against the AI but I have since heard that they are slower than the rest of the GT3 field in sprint races anyway. I like Porsches but do not want to be racing at a disadvantage. Is it possible to race them against a field of other identical cars? Apart from Career and Championship modes, what is the best way to race them against a diverse AI field in shorter one-off events? Please excuse me if I am revealing a high level of ignorance here; I've only been driving this sim for two days.

    There are two Porsches in-game. The Cup car is indeed slower than the rest. So why is it in the game? well, because it participated in the Spa 24H in 2018.
    The 991 GT3 R however is a proper GT3 car which participates in the Endurance series and is properly balanced (irl and in-game) vs the rest of the GT3 field.

    And you are correct, the only way to race this car in Sprint tracks is using the Custom Race Weekend mode and you'll be competing against other vehicles in the Endurance series.

    There's no way to make single-make races but again, the GT3 R is very competitive against the rest.

    I think the porsche gt3 r is one of the faster cars. Its got good power and amazing in the tight slow parts too
     
  5. The porsche 911 cup car, is a recommended first buy in iracing. You can pretty much always find a race, people just love that car. I was hoping they would have more races just for that particular car, with no TC its always fun.

    I'm not actually sure the Porsche 991 GT3 R is one of the fastest cars.

    I think it's one of the hardest cars to drive because of lack of downforce and overall weight/aero distribution.
    If you can overcome these limits it can be fast, yet pushing is much harder than with most other cars.

    I don't think it lacks downforce it's porsche we are talking about and they were in lmp1 and their road cars are beating lap times even though it doesn't have high power as mclaren or ferrari but it has excellent grip.
    I agree on one of the hardest car to get lap times out of

    The Porsche just makes its downforce in a different way. It doesnt have a very large diffuser at the back because its full of engine. This means they run much larger rear wings to the rest of the field to compensate for the lack of low pressure under the car creating drag.

    This is why the Porsche is generally a little slow on the straight as you have to run more rear wing compared to others to generate the same peak downforce.

    By doing that you get more push understeer in the fast corners so its about balancing the front ride height, bars and dampers to compensate. By stiffening up the front you can negate the understeer but it will make the car more nervous.

    Due to the cars short wheelbase its great on the brakes, agile in the slow stuff and with that engine over the rear wheels traction is epic. It rewards big trail braking. Its just to be fast you have to have an edgy less sprung setup to negate the high speed understeer due to the weight distibution and rear wing. Some people like that whilst others hate it.

    Yep that's true it has overall very stiff setup for that rear engine but i like that it provides very lively feeling but sometimes edgy car is generally faster.
    look at esports no one on top is using ferrari yet but instead they choose lamborghini which is similar to porsche.

    Did you mean the rear? Because as far as I know, in order to get rid of the understeering you have to stiffen the rear and soften the front to make the car more prone to turn

    The disadvantage might be that the included setups are not as tailored for those tracks as the setups for the cars that competed in the sprint championship. I expect the Lamborghini, Mercedes, and Audi to have included setups that came from a lot more input from teams/engineers.

    However, the tracks that the sprint championship competes on should be better suited to the 911 (tighter). Herberth also won ADAC GT Masters last year with a 911, which is all sprint races, and uses SRO BoP.

    It does have less downforce due to the engine getting in the way of the diffuser, but it's also the lightest car in the base homologation.

    Yes, apologies it was a rushed reply earlier. It is indeed the opposite to what i said above :)

    Well, this kind of discussion went on elsewhere:

    Read what Aris said, i think it makes sense.

    Personally i do think the 911 GT3 aero is lacking, compared to most other GT3s.
    The fact you can try to overcome that by adding a lot of rear wing is a different matter imho.

    Porsche's strong points are elsewhere.

    I agree.There is a reason why 911 RSR is mid engine now.Rear engine is good and all BUT rear mid engine is used by almost every top motorsports (lmp1,f1 etc).Still fun car i can go down 2 clicks on rear wing still no oversteer on mid-high speed.

    The Porsche requires you a lot of aggressiveness, I feel, it's a car that it's made to just push it in every corner, and you need the car to be nervous by as James P said, and be very very precise on the wheel to being able to handle it properly.

    It's basically a high-risk high-reward car that feels amazing to drive, but you need to have some skill to truly push it to the limit, other cars are easier to get to the 100%, but the Porsche is muuuuuuuch much fun to drive.

    At least to me :p

    Just one thing: Why is the short wheelbase responsible for the car being good under braking? I believe it would actually be the other way around. The thing that should make the Porsche good under braking is the fact that it has the engine at the back, so less of the load is transferred to the front when you brake.
    I'm not saying I know this for sure, and if you have an explanation as to why a short wheelbase makes a car good on the brakes I'd be interested to know what it is, but it's not making much sense to me.

    Yes, you're right.

    I was under the impression that with a shorter wheelbase car there is less weight transfer when accelerating and braking between the front and the rear of the car. A short wheelbase car is generally lighter as well which helps braking performance.

    This has repurcussions with COG too as the lighter you can make the car generally the lower you can get the COG. This means less "dive" under braking and therefore more braking stability.

    A heavier longer wheelbase car i thought would have more weight transfer to the front and therefore have more "lift" at the rear, decreasing braking performance. As you say what also helps the Porsche is the fact that all this weight is behind the rear wheels so lift at the rear is minimised.

    That was my understanding but maybe i am wrong :)

    I believe that when you have a longer wheelbase, if all else is unchanged, you actually get more load transfer between front and rear. It's similar to width: a wider car is desirable for mechanical grip because it gets you less load transfer from side to side when cornering.

    The reason why Porsche is good on the brakes is because the brake bias is as close to 50/50 as humanly possible. The rear has the weight of the engine pushing it down while the front gets the load from the car pitching forward so it loads all tyres almost equally which is why it's so good and stable. A longer and wider car would have very stable aero properties both rolling and squat/dive. Porsche relies on bumpstops to limit that movement instead. Not sure why you get so confused
