Group C Cars - The Best? Worst?

Down-force puts more pressure on the tires what causes them to wear faster.

I think that is false. A car with more rear-biased downforce will have more understeering, causing fewer spin-outs/unintended power-sliding, thus more evenly wearing the front and back tires.

I've experimented with this myself: I used a stock Audi R8 race car at Le Mans 24h for a few minutes, and it was constantly trying to oversteer itself. Increasing rear downforce made the car more stable, and thus less rear tire wear helped me achieve 10 (instead of 9) laps per pit stop, helping me to win the race.

That's what I meant with finding the balance.
Set the down-force so that your car does not over- or understears but don't put it just to the max.
That makes the presure on the tiers greater then needed:sly:
 
Not maxing the downforce opens up the top end as well, any reduction in downforce will lead to higher top speeds on straights. The trick, as has been stated, is to find a balance between stability and speed so that the car can both maintain its rubber as long as possible and handle higher exit speeds to get that edge at the beginning of the straight.
 
I usually run ALL my Group C's with max downforce for cornering at Le Mans, it's has worked well for me before...

Both requires high downforce.

If more down-force simply would give you more speed.
Why doesn't every car have a spoiler like the Suzuki Escudo then?it's

I'm not an expert on these things it's just that my common sens is telling me that it has something to do with it...

2 Things:

1 -- Many people have tested and concluded that the best times in GT5 are achieved with max downforce(balanced per driver taste), even at places like Le Mans. GT5 just seems a little off in calculating drag vs downforce and you don't gain enough speed by reducing wing angle. Actually you don't lose enough by increasing it. If the mega-slipstream enters into it, this compounds the issue. Less DF might help with racing tactics, but rarely with lap times.

2 -- Most(not all) of us are not capable of being as consistently perfect lap after lap after lap as a trained and talented professional. Our setup is usually less than perfect as well. So more downforce --> better cornering with less mistakes --> better, more consistent laps
 
My personal favorites are:
Nissan R92CP
Toyota 88C-V
Bentley Speed 8

I just can't use the Toyota GT-One and the Sauber C9. They sound TERRIBLE in GT5.

Me neither :( I love those cars, but I can't stand the sound...

I hope they fix it...someday... :nervous:

On topic:

The best Group C is the Minolta Toyota 88CV... hands down... :)

The worst... IDK... maybe the 905??? :confused: It was just terrible in GT4, haven't driven it on GT5...
 
Sorry but I had to ask... What car do you guys use for the seasonal cause my R92CP is struggling..
But my fave would have to be the Minolta

I wasn't talking about topspeed....:indiff:

High downforce --> better tire wear
High downforce --> better corner exit speed

I said nothing about the grey part.

I think it's one of the best! No bugs as in GT4 and with its extremely low wheight a monster in the curves. Topspeed isn't the best, because the engine isn't the strongest, but at the same time this makes the car relatively easy to drive. And due to the good power/wheight ratio, the acceleration isn't really hurt by the lower power.

I'd go with the Audi R10 TDI - a joy to drive and its a premium so you can enjoy the cockpit view and the sound of the car while you take on the competition.

I've passed both the C9 and 88-CV (second and first place cars) within the 5 laps of the real circuit tour seasonal with the mid turbo upgrade and racing softs with stock settings.

The Audi R10 TDI isn't Group C car, but it's in LMP or whatever.

Seems we just misunderstood each other.

no problem 👍
 
As the OP is talking about using La Sarthe No Chicanes, I'd think that a high top-end car would be essential. The tyre wear should also be reduced by not having to negotiate the 2 chicanes.
 
Using a tune on my Mazda I get 235mph.... just wondering how it will do on tyres...
 
Best is the 905, extremely predictable, killer brakes and very stable!

Minolta and 787B are a close 2nd, with the r92cp after those. R92CP is good, but doesn't quiet have the speed of the top 3.

Generally speaking lower weight equals better tire wear, so that's about it.

The Audi R8 is still king ding-a-ling though in all fairness. Pretty much a "perfect" LMP car.
Bentley is my favorite, with the new (premium) Peugeot 908 a very close second.
