Chevrolet Corvette ZR1 (C6) RM '09
Well this is hands down the one of the best close-wheel racer money can buy. Not many cars even come remotely close! There have been many tunes of this car already, but this being the first few cars I bought, I took the liberty of enhancing what was already a beast into a menace.

Okay... Back from the Holidays, ready to give Gran Turismo All Stars another shot in the Vette with your updated tune.
Track 1: Trial Mountain - Best Lap 1:18.929 (Old Tune - 1:19.683)
Entry: No complaints here, car feels solid and actually turns in better than before, allowing me to enter slightly later, and still make an effective angle. Car seems to turn tighter and quicker.
Middle: No more understeer! Not only is the understeer gone, but the overall balance and stability of the car is considerably better than it was previously. Car rotates very well under brake and coast conditions. Patience still pays when getting back to the throttle, but as long as you hit your marks the middle of the corner is fantastic.
Exit: The new and improved handling through the center allows the car to rotate earlier, with a far more stable feeling. This allows me to get on the throttle sooner than previously, helping with drive off, traction, straight away speeds, and lap times in general. I must admit, that I did make some LSD changes, as recommended by 'Thunderstruck' after some online testing laps. The final settings, that allow me to get on the throttle with a lot less fear are 5, 10 & 38 respectively. (I might go up on the init/accel a little bit with time.)
Overall: Much, much better for me throughout every point of the track. The most noteable change, outside of the corrected understeer issue I had previously, is the cars stability, which translates to dramatic increases to consistency for me. The car is no longer 'on the edge' which allows some forgiveness. In a 10 lap race, 5 race series, this becomes a key factor. I've ran this series at least 5 times previously and have failed all of them, due to driver error, combined with a tune that didn't promote my driving style. In those previous attempts, I was always able to get to the front, but absolutely could not hold it together, mistake free, for the duration of the race, which always cost me the Gold, and in the end, the series. If anything, you could add a little bit more turn, or free up the car a bit, to give it just a little extra bite when you need it.
Grand Valley - Best Lap - 1:43.329 (Old Tune 1:44.244)
Well, as I described on the last track, the car was extremely balanced and stable. So, when we head to a track with higher entry speeds, and tighter corners, this usually translates into a slight understeer issue, and this was no exception. Don't get me wrong, it was leaps and bounds ahead of the previous tune, allowing me to cut 9 tenths off my lap time. But I did experience some understeer from the center out on this track. This tune and car, when on this track becomes a coasters dream. If you like to make a moderate entry, meaning middle of the road, between aggressive and modest, just a solid, strong entry, then coast through the turn, waiting for the perfect time, to hit the gas and drive away, this tune has the ability. I found myself comfortably out front, but that R92CP Race Car never left my rear view, with the 787B tucked in right behind him. The tune is comfortably capable of winning, if you stay clean and smooth.
Green Monster, the ring... 6:34.397... (Old - 7:01:931)
This is where we see, all of the increased control and stability reap rewards. The car still hates bumps even at 16 / 15 ride height.
Had I used the proper gearing for the final straight away, I probably could have pulled this one off. But 4th place here and will probably crush the series hopes, due to the R92CP running 2, 1, 1 so far to my 1, 2, 4, leaving me 50 points back. I'd need to win the next 2 in a row, with him finishing 3rd at least once to pull it off. Which wouldn't be so horrible, if he didn't start in P1 every f#%$ing track. Either that, or I need to go out of my way, to force him off the track early and try to win that way, but it almost always results in me taking myself out. I'm going to break down, and use a different car
The ring - 2:23.534
The one and only part of this track I like, is the big down hill spiral. Other than that, I dislike this track. Higher Speed and lower banking corners magnified the issues I had at Grand Valley, and made the car feel like the old tune again. Just not enough turn through the center and out. Understeer monster for me on this track. I'm sorry to say, I hated this tune on this track. 4th place finish, game over series.
All in all, this tune is great, I just need to find a way to fine tune it, to suit my personal needs. Great update though, without a doubt. Thanks again for taking my review into consideration and I'm glad to see it help your tunes progress in a positive direction.
