Just been testing the Camaro SS '10 more. I've been increasing and decreasing weight and BHP, trying both extremes, and have made the car a tiny bit easier to control, while still maintaining its fast pace (still slow in a straight line compared to some of the other cars though). I also just went for 22 laps in a run with it. After the 18th lap, I started losing about 2 seconds a lap every lap, and pit when I had about 3% of my left side tyres left.
I'll be messing round with some of the other cars now, to see what I can get out of them.
EDIT: The Corvette Z06 (C6) seems very similar to the Camaro SS. They're very closely matched in all areas- cornering, straight line speed, tyre wear, and overall laptimes.
EDIT: Comparison time, now that I've done a full tyre run on the Z06:
Both cars have the same rate of tyre wear and both set very similar/identical laptimes throughout, BUT, the difference comes in HOW the tyres wear. The Camaro SS '10 wears its left side tyres mostly, and this causes the car to develop oversteer as the tyres wear down. The Z06 wears it's front tyres mostly, meaning that it develops understeer as the tyres wear down. The only other real difference between the cars is that the Z06 is 2mph faster before the first braking point of the lap, but loses this slight advantage in the final sector.
I'll summarise each car I test below to make it easier:
All cars are tested with 0 aerodynamics, maximum ballast, same ballast position (0/the middle), the same gear ratio, the same brake balance (5/5), the same LSD settings, and the same suspension adjustment (ride height reduced to 5 above minimum on both ends), and have been fully upgraded with all parts. All HP increasing parts have been changed to stock, apart from engine stage 3 which cannot be undone (same goes for weight reduction stage 3). Some HP increasing parts may have been added back on to get the PP up to 515 without removing ballast. If/when your car wears its engine in and gains BHP, reduce the power limiter some more or remove an HP increasing part if you can.
Camaro SS '10: 23 laps on tyres, 1:19.0XX for lap 18 before times dropped off a lot, develops oversteer through the run.
Corvette Z06 (C6) '06: 23 laps on tyres, 1:19.0XX for lap 18 before times dropped off a lot, develops understeer through the run.
Lotus Evora '09: Tried it out to see if I could fix it. Too much grip in corners meant that it lapped 3/4 of a second faster than the SS and Z06. Reducing BHP to make its laptimes drop caused its tyres to last for too long. Giving it sports soft tyres made it have too little grip in corners. Couldn't fix it, gave up on it and won't include it.
BMW M3 Coupe '07: Same pace as the Chevrolets. A bit faster on straights, but a little worse in corners. 20 laps on tyres, but I smoked the left front a few times under braking, and it was the first tyre to wear out because of this. Can make 23 laps like the others. Lap 17 was a 1:18.6 and lap 18 was a 1:19.8, due to the increased tyre wear on the left front from my errors. 1:19.2xx is between those 2 times though, and what I think lap 18 would've probably been close to, if not slightly faster than. Develops a mix of understeer and oversteer through the run.
Nissan Fairlady Z (Z34) '08 (Nissan 370z): Plenty of oversteer throughout. Requires a bit more delicate driving through the slower corners, or a slightly different setup. If driven properly, can do the same as the previous cars. I can't be as precise on the throttle as I'd like to be, because I'm too used to X and O on the DS3 and am horrible with using any other buttons to brake and accelerate. This and the BMW M3 are the fastest cars in a straight line of the ones I've tested so far. I used the suspension, LSD and brake balance settings from this tune to make it driveable enough to test for a few laps: https://www.gtplanet.net/forum/showpost.php?p=4346037 If all else fails, try the car with a rear wing on it. EDIT: Ran it again with the same settings and I suddenly have better control over it, and am just about on the pace
Maserati GranTurismo '08: Has the pace of the other cars. A tendency to oversteer meant that I wore the tyres out after 17 laps, but it's nothing that a tune can't fix. If moving the ballast or using a tune doesn't do the job, try a rear wing.
Ford Mustang V8 GT Coupe Premium '07: Oversteer in the same places as the other cars, but understeer absolutely everywhere. This puts it 2 seconds off the pace. Moving the ballast all the way to the rear improved the times by 3/4 of a second, but that's not enough.
Nissan Fairlady Z Version S (Z33) '07 (Nissan 350z): Finally another car that has the pace. Should be able to make 23 laps like the others, with the usual drop off of pace after 18 laps. Mostly develops oversteer over the run, but theres some understeer in places too.
BMW Z4 M Coupe '08: Another car with the pace. Should also get the same 23 laps out of it's tyres, with the usual drop off of pace after 18 or so. Develops oversteer through the run.
So, that's my testing done. These are the cars that I think we should use out of all the ones that were tested:
Camaro SS '10
Corvette Z06 (C6) '06
BMW M3 Coupe '07
Maserati GranTurismo '08
Nissan Fairlady Z Version S (Z33) '07 (Nissan 350z)
Nissan Fairlady Z (Z34) '08 (Nissan 370z)
BMW Z4 M Coupe '08
EDIT: A question, how long do we think the races should be? Ideally I'd like it at a distance that means we have to pit for fuel at least once. On the current track and depending on the car, fuel will run out right around the end of 3 tyre runs (tyres you started on and 2 additional sets from pitstops), which is something like 60 laps, and may be too long a race for some people.
Also, will the weather be changeable? If so, we need to remember to set "grip reduction on wet track/track edge" to "real". If we don't, our racing hard tyres will have better performance in the wet than the intermediate and full wet tyres.
