Struggles with GT1 & GT2 2005s

I‘m really struggling to drive the mid 2000 GT1 & GT2 cars. I can‘t brake them properly, it‘s either to soon and I lose a lot of time or it‘s way to late and I spin.
Mid corner, I often feel like the car is not turning and I spin. When I accelerate out of a corner, the cars get light, steering wheel is going crazy and I spin.

Maybe someone here has an idea about what I‘m doing wrong? I like the looks & sounds of these cars, bur I can‘t drive a single decent lap and had no fun with these cars at all.

 

Moza R9 and GS Wheel (a modern gt/formula wheel, I don‘t have a round wheel). I use Asetek Forte Pedals.
At the moment, I don‘t habe a shifter, but I only shift i situations where it‘s sane to only have one hand at the wheel. But I‘m getting a shifter in the coming days.

 

any car within the gt1 2005 class you are having particularly trouble ?

Personally i did a league season in the maserati and found it drove very well, even with 0 wing.
These cars really punish too aggressive trail braking and are also sensitive to downshift locks.

Id recommend testing a brake pressure of like 95% - 98% with them.

 

Depending on pedals and leg feel i would go even lower. I use brake pressure at 82%.
T-LCM pedals.

 

Smoothness is essential, I've found- make sure to blip the throttle on downshifts, don't trail brake too aggressively and be very gentle on throttle out of corners (you can get away with more in the GT2s, barring the Panoz, but the GT1s are very quick to remind you they have 600hp and no TC) and they become a lot more manageable. Very much a "slow in, fast out" type of class

 

Ok, I‘m embarrassed to say that on a racing sim forum, but I don‘t know what „to blip the throttle on downshifts“ means. Can you help me out please?

For example modern Monza T1: I a modern race rar, I slam the brakes at the 150m sign as hard as I can, while shifting the gears down like a machine gun from the highest gear to gear 1. As I do this, I trail of the brake and at the apex I step on the gas again.
If I do this in the GT1 or GT2 cars, I die

I need advice!

 

Tap the throttle pedal to increase revs on each downshift. Modern cars do this automatically, these manual-sequential cars usually do not. Same story for the old IndyCars, for example

Edit: The reason behind that is that the revs drop too low relative to the driven axle, meaning the engine and the axle are rotating at different speeds, and that causes instability. It's like a half-step between paddle shifting and full heel-and-toe driving, and in real life, these GT1 cars were actually often still driven using heel and toe despite being sequential to decrease wear on the mechanical components.

 

In general, you tend to want to drive the older stuff slightly differently than modern stufff, smoother on the braking and with throttle, definitely no machine gun downshifts like in some F1 car.

With these cars especially, you get quite a bit of rotation from using throttle, I don’t rely on keeping the front loaded and rear light with deep trail braking to get around the corner

 

Generally smooth is key here, modern machines have tons of driving asists that allow the drivers to drive them like animals, they're meant to be abused with aggresive inputs since you're relying on the assists to do most of the work. Older cars don't have that, so you'll need to readjust your inputs acordingly, smoother gear changes, use a kick of throttle in every downshift to stabilize the rear, and usually try to enter corners slower than you'd think you can, you don't have ABS to help you with the brakes.
I'd do that before going into any setup menu and making changes.
If you want to learn about shifting with any car this one is an oldie but still very relevant:

 

Thank you all, I will try these cars again & I will try to be smoother. I have ordered a shifter and I believe that my driving with these cars will improve with that.

Anyway, more tipps & tricks to tame these cars are very welcome!
What setup changes do you apply to the GT1 or GT2 cars?

 

Don't assume you can drive these cars like a GT3. They are not easy, and that challenge makes them fun.

 

Honestly, I would recommend just try and get accustomed to driving them before you look at setup changes. It can make a difference, but I can see from your replies that you're unaccustomed to these sorts of cars so it's more important you get used to driving them on the limit before you make any changes.

So key points to remember: No traction control or ABS, blip the throttle on downshifts (also applies to driving H-pattern cars), roll the power on SLOWLY - feather the throttle with barely any input, don't just floor it all the time, and brake earlier than you think you should whilst you're learning the cars. As you learn how to handle them, you'll naturally find out how late you can start braking.

Here's a foot-cam from a V8 Supercars driver - watch especially his throttle and brake inputs, see how smooth they roll on and off. Letting the brakes 'tail off' slowly is also key to cornering but takes some getting used to when you're actively using the clutch on down shifts. And yep, that's two feet on the throttle (probably to conserve energy)

 

Also, if you want an "Easy mode" car that uses these driving techniques with no assists, go for the Ginetta G40 GT5 It's actually a lot of fun in its own right, but it's a lot more forgiving than the faster cars that need to be driven this way, e.g., GT1 and GT2, Super V8.

 

Any thoughts on getting a round wheel for the 2005 GT1/2 & LMP1, and the late 1980 F1 cars?

Seems like it might be a worthwhile investment for these machines.
