Was testing out a different RUF tune, after being disappointed, decided to search for what else was out there and came across this.
Test Track: Grand Valley Speedway
Best Lap: 1:52.354
Previous Tune: 1:53.265
Test Track #2: Trial Mountain
Best Lap: 1:23.583
9 tenths quicker, and the car was much more enjoyable to drive. With 1 exception... Under hard braking, this car is absolutely un controllable.
This little tid bit, prevents me from getting into the :51 bracket. I simply can't enter the corner, even closely as hard as I should be able to, and I lose a lot of time slowing down so much earlier. Trail braking seemed to be the best option in this scenario, but it definitely hurt my lap times.
Corner Entry... When trail braking, the car was very smooth and handled well. If I needed to turn tighter, I could tap the brakes and it would help aim the car, although it's not advised to have to drive this way, but it worked for the time being. Turn in on mild corners seemed fine, definitely while coasting.
Center of the turn: Under coasting conditions it worked well, but at times where I over drove the corner a touch, I was literally paranoid to touch the brake peddle to get slowed up and correct the issue. So I was forced to coast beyond the apex, and just live with an understeer condition, resulting from driving in too deep. This hurts my exit and screwed me up, and costs me a lot of time throughout the track.
Corner Exit: With the exception of the above forcing exit issues, the exit felt pretty good. I caught myself catching the tail end at times if I got to full throttle before the car was ready. On the 1-2 larger sweeping turns, I did sense a touch of understeer on exit, but all I had to do was let off for a sec, and it helped the car get up and off the corner.
Overall, if I could get rid of the Braking issue, which I'll try to do with the Brake Balance, I think this tune would be great. It's hard to fully review it with this rather large issue I'm having, but the above is the best I can do for now.
Update!
I played with the brake balance, and saw minimal enhancements of control under braking, so my next step was to go straight to the LSD.
After some rather quick and abrupt LSD guesswork, I got to the setting of 15, 18, 10, ran a few laps to get use to it, and then ripped off a
1:50.306. A full 2 seconds faster at Grand Valley with LSD adjustments. These are rough figures, as I didn't take the time to fine tune them, but there's work to still be done to both the LSD and in my humble opinion, the tune as well. Using this LSD set up, I was able to drive the car a lot harder and more realistically. This unmasked the core of the suspension, where I came to find, that the car has too much turn in, not enough turn out. Turns too much on corner entry, and doesn't turn enough on corner exit. The car doesn't seem to appreciate quick weight shifts from corner to corner, but with the new LSD settings, I was at least able to control the car from spinning. Trail brake is still required for the first corner to not absolutely lose the car, but I can live with that. My personal opinion, is that the car needs most attention to its Toe settings, both front and rear, as I have a feeling that this is where I'm getting the turn in/turn out issues. 0/0 isn't very common throughout many tunes across GTPlanet. I might try playing with some more fine tuning tomorrow, but I didn't want to waste much time on it, when I don't feel the core of the set up is quite suited for me just yet.
Update #2 Adding - rear toe, stabilized the corner entry very nicely. I used -.07 on the rear, and didn't touch the front. Dropped the front Sway bar to 4, and then used a spring rate of 9.9 / 13.0
This is the stock front to back ratio of 43% - 57% stiffened by 15% all around. The softer front springs also helped the car transfer weight under braking. This allowed me to put up a new personal best of
1:49.966 which was my goal for the night, So I'm headed to bed! But the car still understeers from center out on the higher speed, longer turns.
EDIT: Performing Chassis maintenance in GT Auto, drastically reduced everything I complained about. Added a 2nd track & times to all 4 tunes tested.
