Title: Balancing changes for the 2.13.0 UKGTR pack
Post by: Legzy on June 20, 2010, 10:36:49 PM +0100
Well I know the GTC Spyker is too fast for it's class & have a couple of other thoughts too, but what balancing changes do you think are required?

Maybe you think there is a car in a class that is too good? If you know what advantage it has, that might help but is not critical.

Maybe you think a car/cars are too slow in a class & so they never get picked... can you tell me what's wrong with them maybe?

Obviously next season we'll only be running two classes maximum of the four, but they all had an outing last season, so we should know what needs tweaking.

If it can be done....I'll love to see the Z4 unshackled and moved up a class to GT2....not sure if it would be competitive though?

Z4 doesnt run in GT2 i dont think.

Could upgrade the BMW E36? GT2 a tad to make it competitive with the 997's and F430's. The current Beemer in ALMS GT2 is racing well with them.

I'd like to see a GT2 class C6 vette too.  8)

I'm not sure Lazlow was too concerned for authenticity Mark!

I'd agree the GT2 beemer does need a hand especially arond the slower tighter tracks. Not sure the new 'real' gt2 beemer has been released by anyone yet?

GTC aston is a dead dog and probably should be removed as i dont think there is anything that can save it which is a shame. I've always struggled with the TVR and would have said it needs somthing but H@L has quashed that thought with his speed in it!

I was only saying last night a lower class Corvette would be nice.

When testing GTCs for Nurb GP on Sunday I noticed the RS Porsche was at least 1 second slower than the 997 Cup car that I drove in the race.

IMHO with all the balancing that has gone on previously, we could really do with a couple of the top drivers here getting together to test the packs to see where we are.

Don't forget, though, that it's not just about single lap pace, it's also about tyre degredation and fuel use, and their effect on pit stop times.

One or two people do prefer the 996 compared to the 997 version

Dave is right about the fuel use and tire degredation, but only if the race length is long enough for that to come into play. I didn't run too many events last season (only 2 I think) so it is difficult for me to really speak to the subject with a lot of experience to back me up. I do remember the pit time for my 997 GT3 vs. the Viper were identical. I may have taken on 1 extra gallon, but that should amount to 1 second at most. I was shocked to see that outcome in the pits considering the GT3 should sip fuel compared to the Viper. I thought for sure I was going to win that race at Brno prior to leaving the pits.

There are so many setup adjustments for these cars it would take hours and hours to effectively measure the true performance potential of each. Track choice will expose a particular car's weakness and testing on that type of track is necessary to do so. Testing on multiple tracks takes time. Has all this been done before?

With my limited exposure, it seemed to me the Spyker stood out. That being said, I should probably go test it before passing judgement.

Just as a reminder for me:
What's wrong witha a Porsche GT3?
Nothing  :) Racing other similar cars would be great for me. I have not found racing the totally mismatched Viper, just wait for the pitstop (yawn), and the awful Vertigo, just waiting to get rear ended, satisfactory at all. Any other class offers more for me and maybe just me to be fair :angel:
Hey SBG, I think you're hinting at balancing changes that are required by this class... any chance you could add your balancing thoughts on the 'Balancing changes thread (https://www.simracing.org.uk/smf/index.php?topic=8032.msg142176#msg142176)'. I think you're saying that the Vertigo has too much advantage come the pit stop, but please clear up there :)

The GT3 cars are well balanced over an enduro but I don't enjoy racing against either the Vertigo or Viper, easily the popular choices, for reasons I've explained. GT3 doesn't work as well as GT2 or GT1 for me. Unless, you've got something to spice GT3 up? :angel:

hello mike,
sorry, but i must totaly disagree about fuel in vipercc and 997Gt3. viper is with a BIG gap the car in in this class which need the most fuel. there is a totaly different between other cars.
the most big different is between vipercc and i think it was RS (which can easy do 0 fuel tank races), Viper loose much more then 10sec. against this car. and i am sure against your car it is around 5-8 sec.
please test this for your own, it is so much huge fueldiffernt between vipercc and the other cars like gt3, rs, 430/360 and many other, think Z4/aston was the 2nd bad car in fuel in this class.
spyker got a 10kg? penalty during last seasen, and was only a little faster for me in beginning of season 0.2-0.4 sec. and need more fuel then gt3 and rs, so cars are equal. viper is in any tracks fastest car of class, but in other tracks totaly dump and like i say before, is totaly sh.t in fuel and tyres.
hope this help a little

I agree. From my experience of the GT3 viper last season it is hopeless on some of the slower tracks - slow and suffers from poor tyre and fuel performance. On the faster tracks it is potentially the best of the GT3's but again the poor tyre wear and extra fuel just about brings it in line with the BMWs and Porsches. Not a good car to pick overall  ::)

2010 GT3 real world racing seems sweet. Surely would be better to get the new mod altogether. :-\

Don't forget, though, that it's not just about single lap pace, it's also about tyre degredation and fuel use, and their effect on pit stop times.

Indeed. The cars are currently balanced with 80 min races in mind. If we are going to reduce race times then it will really need to be 40 mins with 2x fuel and 2x tyres I would have thought.

PS. According to my spell checker, you spelt degradation incorrectly Dave. (Sorry, could not let this rare opportunity pass :P ;D.).

Valencia GP. Lambo vs Corvette C6R, both tested with 100 litres, medium tyres, 2-9 wings

Car / Best time / Fuel per lap / Tyre wear (5 laps)

Lambo / 1:28.5 / 2.93 lit / 2.7 & 2.9 (F) 2.9 & 3.4 (R)

Vette C6R / 1:28.1 / 2.78 lit / 2.7 & 3.1 (F) 2.5 & 2.8 (R)

Summing up: in one of the tracks which should most suit the Lambo (continuous series of corners, it only has 1 long straight), the Corvette is still faster. It also uses a bit less fuel and just a bit less tyres. But its a bit more difficult to drive, has to be said as well.

On the other hand, as I said in Paul Ricard (long straights) I found a higher difference, over a second per lap. Imagine in Road America or Monza...

Conclusion: the Lambo needs some more power (I've always said its a bit too slow, in the straights and overal as well, as its the car using most fuel too). The Vette is probably the best car out there overal, but it is pretty difficult to drive so if its slown down it only has to be ~10kgs (or the corresponding amount with engine power or whatever).

yes busi, lambo need help.

i did not test UKGTR lambo, but i did watched the wheights before season of the cars and lambo have actual +15kg more then orginal and 575 have -5kg then orginal.
so i did know lambo is to slow, think lambo need -5kg too (20kg less then actual), but best is lambo -5kg less then 575 bacause of much fuel and slow high speed (important in race too)
but then lambo specialist busi win every race in this car :laugh:
lambo 1175kg or 1170kg is good, but stay with orginal fuel need.

servus

edit: i did see that lambo have already a better fuel need, so equal wheight to 575 is perfect 1175kg.

hello,

i did not test every car in the carpack,
but 575 is my main car and get other cars equal to this car i do write (of course i know any are better in fuel in tyres, this i have already in my calculation)

i do think that lister need -5kg (or perhaps -10kg as maximual, not more because of very good fuel and michelin tyres in this carpack), car is 0.2-0.3 sec. slower then 575/aston (before aston got wheight last season i think)/550
10kg = around 0.15sec. in an average 1.30 min. track for GT1 cars, but of  course little different from track to track.
