I began the Le Sarthe 24 II race earlier today with the Minolta. I had tested the Minolta to get the best racing setting on the track with neutral balance. However once i started the race there was a major problem with the rear tyre wear of the tyres. I was using Super Hard tyres front and rear and the rears were nearly red after 6 laps while the fornt where dark green,just got out of being blue. I stopeed and wetn and di some testing and no matter what i did the rear tyre wear is awful! It would not be so bad if the AI cars were the same but they were not, there tyres lated twice the distance as mine. The tyre wear is the same if i use Stage 4 turbo or not, my TCS is set at 10 and i set my LSD accel to 60 and tried everything i know to lower rear tyre wear but nothing worked! Can someone please help me, i really need/want the Bentley Speed 8!
 
I have had the best results with the Audi R8 and Bentley Speed 8. The Group C cars do have worse tire wear, especially the Minolta Toyota.
 
Well i will take your word for it M Power, i am going to purchase a R8 and do the Le Man 24 hour again and see if i can win the Speed 8! I take it that is what you did, will i need any power upgrades on the R8 to win? Down the straights the AI only does 211mph s are power upgrade neccasery?

I have an R8 and both the Pescarolos. Don't be fooled into thinking the '03 Pescarolo is not as good as the '04 version because it has less power. The '03 Courage C60 gets significantly better tire life than either the '04 or the Audi R8, giving it a significant advantage.

In shorter races the '03 can use softer tires. In long endurance races it will require far fewer stops. Use Stage 4, stock settings (but turn off ASM and turn the TCS up to 7), and adjust the gears for the track.

The '03 Pescarolo is a great car.
 
R8 has tire wear but not as much as the minolta. maybe you could break less or just setting up some TCS so that you dont peel out coming out of a corner.
 
Thanks for the heads up, Zardoz. I only have the '04 Playstation version and have not yet even tried to go endurance racing with that, I was therefore not aware of the superior tire wear. Good to know. I am currently saving up to buy the '03 version anyway, so I am looking forward to taking it to an endurance race some time.

I am impressed! I just bought the car and went for a B-spec test with it at Fuji. Using medium tires all around, the Minolta gets from 6 to 7 laps, and the Audi R8 gets 10. The '03 Pescarolo did one laps better, but when I switched from medium to hard tires for the rear, it extended that run to 16 laps. Usually when I use anything harder than medium tires, the car tends to pit because of low fuel and not because of tire wear, but the lap times are uncompetitive. With this setup, however, the '03 Pescarolo almost matched the tire wear with the fuel consumption and continues to put in competitive lap times. That means that it can beat the other cars on both speed and pit strategy, whereas before my advantage was usually in speed only.
 
So what car should i use to win the Le Sarthe II race? I only want to do it once as i hate the idea of waiting over 8 hours to find out i lose!! All i want is the Bentley! i have just bought a R8 and while its tire wear is better than the Minolta the rear tyres get thrashed just as bad! Why does this not happen to the AI cars? I hear of people winning with like 12 laps over 2nd place but when i used the Minolta i either 3 seconds infront or 15 seconds behind! GGRRRRRR!
 
Try it with medium tires up front and hard tires in the rear. You should be able to squeeze out five, maybe even six laps, out of the tires with that R8, and even though you will still have to pit more often than the AI, the speed advantage should make up for that.
 
soften the car up a bit and raise the ride height a lot
I ran Le Sarthe last night for a few laps and I'm pretty sure it was bottoming out
 
The AI struggles with the tyre wear on that Toyota, always quick, it is the first car in the pits usually! I can only offer the advice of reading the set up guides. Tyre wear is caused by putting too much energy through the tyres, and you need to put more energy through the fronts. Back the brakes right off, 5 front, 1 rear. Drop the ride height at the front, or raise the rear a bit, so you can stick softer springs and dampers on the back. Basically soften up the back end, and it does not put as much stress through the rears. Good luck.

Tried a search but couldn't find anything specific. I'm trying the Le mans II 24hr race, started with a few cars Minolta Toyota, R8, Formula, but my driver keeps losing it on the straight and goes into the wall any tips to stop this.

Cheers

What is your speed setting? Seems anybody's B-Spec driver should be able to stay on the road at "3". Mine has 5500 points and can now drive the Audi R8 perfectly at Sarth II on "4".

I'll check, but I would think the R8 in stock form is so fast on that track that it could probably beat the AI Sauber C9 and Minolta Toyota 88C-V on "2".
 
I know it will be down to the set up I have for the car, but as I like the way they drive for me I dont want to change it to much (the set up I use is the one posted in GT4 tune shop, but with some changes to suit my driving style).

Old Pedro(B Spec name) had no trouble at all on Le mans I, I suppose he just get bored driving down Mulsanne and just decides to end it all.

try to adjust brake bias. stiffen front or soften rear.
 
I am going to do a bit of testing with the Toyota 88C tonight, I won it last night, then used it to do the super speedway 100 laps. My observations were that "2" was quick enough, and that 3 lead to spins occasionally, in b-spec. I worked on the suspension on the back end, using principals gained from Avatis and Zardoz school of tuning. I will test it tonight at sarthe, to see how long the tyres will last, and how much fuel it uses. I'll post the results to the appropriate section, I am sure someone has posted a set up somewhere, I will add to that.

The R8 was consitantly getting 7 laps on Hard fronts and superhard rears. This perfectly matched the ammount of fuel available, if I was paying attention when doing the pitstop, I was stopping the fuel going in at 75/80 litres, as that was enough to bring it into the pits with vapours :-)

And FYi I decided to see what happened when you ran out of fuel... the car drops to an 80 km limiter, and crawls back to the pits. Annoying, but not as tragic as it being all over!
 
First of all, Take the TCS down to 4, Never put it up so high unless the car calls for it. The TCS is for traction. Placing too much WILL ware down you tires fast. Then go to your suspension feild, Look at your camber and toe angles. Play with these setting for tire useage. These setting is for the tires. How much grip and ect. I have this car also and I could get 10 laps out of it. Depending on what track tho. I could get a straight 10 laps on "Tokyo" tack. I also finished the championship race in Pro hall. I could be a beast if you set it right and could handle the unsteadyness at high speed.
 
Ok, I had a fiddle with the setup, and tested it by starting the sarthe 2 24hrs race... I did not have time to complete it, but I did run 3 stints with the B-Spec bob to determine exactly how far it would go on a set of tyres He was constantly set to 3, so as not to mince the tyres.

Before I go any further, I would like to say this was an enduro test, not an ultimate speed test. My goal was to get the most out of the tyres.

The first stint I did on RM/RSM and trashed the fronts after 5 laps. So I pitted, and got a set of hard fronts on it. Up to this point Bob had been doing a best of 3.18.539. Off out on RH/RSH tyres to find the limits again. There was another Minolta running in the race also, it pitted on lap 7 ( very hard rubber i think! ) Starting lap 12, the tyres at the back were looking sick, bright orange, but watching the car it did not look too unhappy, and it made it round to pit happily. 17/80 fuel was left, so decided to see if it was any better to short fuel the car, hoping a little weight was reduced per chance. With 17 left, I reasoned that I only needed 65 in the car before the tyres were ready for the dump again. I dialed the pace down to 2, and headed out again, ( or rather Bob did ). With the pace dialed down, Bob was doing 3.21's consitantly... not enough to keep up with the C9 Sauber. I pitted on lap 19, after another 7 laps, conclusion, the reduced pace and less fuel did naff all good! I sent Bob out for a confirmation run on the same tyres, at pace setting 3, to see if we could catch the Sauber.We got to the end of lap 26, and pitted. At this point I decided to have a steer, and see if I could make up the 8 secs to the Sauber that were lacking, all pit stops being equal. I made it to Lap 31 before the tyres looked too bad to continue. I concluded that if I had gone fron the start with the RH/RSH combination on pace 3, it would have looked OK, and the fact that I took the gap from 50 secs to 10 secs in 5 laps, showed that the occasional 5 lap excusion from the A-spec component ( me ) would secure a win at Sarthe 2.

Now, since you have been forced to sit through this rubbish, here are the settings :-)

All listed Front / Rear respectively where applicable

Brakes 9 / 5
Springs 13.5 / 9.5
Ride 67 / 75
Bounce 5 / 3
Bound 9 / 6
Camber 3.0 / 1.5
Toe 1 / -1
Stabliser 5 / 2

Ballast ---- nothing

Downforce 63 / 88

LSD init 25 / acc 55 / dec 14

Driver Aids Ov 8 / Un 4 / TCS 2

Use the transmission trick plus a little tuning to get
1st 2.900
2nd 2.100
3rd 1.650
4th 1.330
5th 1.080
6th 0.880
Final 3.500 use 3.400 if you have the big blower, it will pull it.

Comments welcome
 
Hi all.... I can now CONFIRM the solution TO WIN IN "SARTHE II"

The car: The Minolta.

Options: Buy the level 4 turbo, Tyres-> Hard and Super Hard, Refresh the body and rebuild it.

Change oil.

Before you start the race, change the set up, just the tyres -> Front: Hard and Rear: Very Hard. I change the ration gears to 20, but i think is not necessary.

:D Thats it! Run on speed "3". :D



Resume:

I start the race in speed 3 and will maintain it to the end. First I had Hard tyres on the Front and Rear, but after 4 laps I already was in the Pit. After the first lap I was already in first place. When I stop in the Pit, almost all the cars past trought me, I was in 5º place. I change the tyres - Front: Hard and Rear: Very Hard. At the 6º laps, I had already one lap over the Ford GT 40 '69 (6ºplace), at the 9º laps, I was in 1º place again. I stop at the pit again after the 10º lap. I changed the tyres again to Front: soft and Rear: Very Hard, when i left teh Pit I was still in 1º place. It toke me only 5 laps to come back to the pit, so I change the tyres again to the best set up - Front: Hard and Rear: Very Hard.

After 20 laps, I was sure to win, I just need to wait 23 hours more :) The best time I got in those 1º hour was "3'11.282" the speed is +/- 330 Km/h.

The other cars goes to the Pit moreless after 8 laps, but the Ford GT 40 '69 only after 16 laps!

The best thing is... you don't hit any wall !!!

Good races to all !

Serge.

PS: This morning after 13 hours, I still had the 1ºplace and 2 laps over the 2º place (Sauber Mercedes).
 
Hello, the only problem with the Minolta Toyota is the suspension travel is too little in the rear for high speed BUMPY tracks, like Sarthe. Under repeated loading it begins to collapse, effectively lowering the ride height and unweighting the rear tires enough to spin. It is not too much power or weird science, your obvious clue is the sparks. If you put B-spec Bob in the drivers seat and go for a ride on the tailgate, ok, air foil then, you will see clearly, as he accelerates past 200 mph (300kph?) sparks start to fly out the back, just like when you drive over the rumble strip. If you then go and do nothing more than raise the ride height- I used 77mm with spring rate 15.7- and go back out with Bob, voila! Your tire wear problem is now gone, wear is consistent with the Sauber C-9 and R92CP.
I am puzzled because this was explored and discussed in the "Minolta 88C-V tune" thread I'd started and several people who posted on this thread participated in that discussion but seemed unaware of what we'd learned.
 
Just thought i'd share my settings for the minolta.

Its a combination of a couple of the tunes mentioned on this site.... (i'm claiming no credit...) I thought i'd post it as some of the other posted settings didn't work for me on the sarthe tracks.

it works really well and i won both sarthe races with it by a large margin.

Buy all available parts... using turbine kit stage4.... No nitrous tho.

Brake bias : F=9, R=5
Spring rate : F=13.5, R=15.7
Ride height : F=67, R=77
Bounce : F=5, R=3
Rebound : F=9, R=6
Camber : F=3.0, R=1.5
Toe : F=1, R=-1
Stabiliser : F=5, R=2

Gears. Use Tranny trick.... so auto is1
1= 2.900
2= 2.100
3= 1.650
4= 1.330
5= 1.080
6= 0.880
Final=3.400

Downforce = Max front and back.

LSD.
Initial = 25
Acc = 55
Dec = 14

Looks neat, do you use a wheel or controller?

B-Spec for the 24h races ;)

I'm not sure of the exact margin i won by, but on sarthe I.... i started the race, set the speed to 3. overtake to on.... then left it.

Checked the race with about 8 hours to go, and i was 9laps (or 5laps, i forget which.... i'll have to test again..... either way it was a large margin) ahead of the nearest car.... :drool:

It's right to say that the Minolta Toyota is hard on tires, but that should not be a problem thought. I won the 24h II in B spec with it. Here are my settings (very simple) :
- Super hard on the Rear
- Hard or medium on the front (1 lap less with medium, but the car seems to handle better, it's a choice to do)
-Stage 4 turbo
- no TCS/ASM
With these settings, my b spec driver makes 6 laps. It's not a lot, but as he is really quicker, it's largely enough.
I won the race quite easily, despite the fact that my car did twice the number of pit stops than the 787B (my main competitor) did.

So it's possible to do it, but your b spec driver has to be faster than the other competitors.

Regards,

Snypa
