I'm just passing through this thread to say that was positively amazing to watch.
Absolutely. This video representation of his epic Cappuccino victory over not one but two GT40s is fully captivating and the work of a GT 2 master, one whose artful tuning and driving magic have touched the hearts of every driver to experience said video, inspiring some to achieve GT40 victory or die trying and condemning others to madness with the overwhelming and for many unattainable majesty of it all.
Hehe, thanks guys. Definitely don't consider myself a GT2 master though, at least not from a driving perspective. Glad the video helped out. Yeah, the settings I used are pretty weird, let me walk through them to attempt to de-mystify them:
Spring rates: went with 2.0 / 10.0 to go for as much oversteer as possible, as the super soft racing tyres are giving the car massive grip. Setting the front springs as low as possible, combined with high downforce, subjects the car to a phenomenon called "ground effects". This lets the car take extremely tight turns after elevation changes, but it also makes the car more difficult to control if you're not careful. Try these spring rates on Trial Mountain and you'll see what I mean when you get to the sharp left corner before the final straight. The stiff rear springs won't be affected though and will keep the car stable. You can set the front springs to 4.0+ to reduce the effect.
Ride height: this is the key setting that lets the Cappuccino keep up with the GT40's. GT2 has a glitch where setting the front height low and the rear height high boosts acceleration. The 'downside' of this is that you're moving the car's center of gravity forward, which makes the car more difficult to turn. Thankfully, the Cappuccino is barely affected by this, and still handles great.
Dampers: same as springs, 1 / 10 bounds and rebounds for max oversteer. GT2 dampers are broken. There's two ways to set up dampers: soft front / stiff rear for oversteer, or both sides soft to let the car handle bumps more easily. 2 / 2 bounds and rebounds work well, especially on PAL where 25 FPS physics make bumps more extreme. Personal preference.
Camber: 2.2 front is my go-to setting for most cars, seems to reduce understeer the most. I kept the rear camber at 1.0 as the Cappuccino didn't really need any extra grip in corners. Could be lowered to 0.5 to help the car turn even more, or raised if the car is losing grip easily.
Toe: another classic broken GT2 setting. -0.20 / 0.20 is my go-to for making pretty much any car turn more easily, for basically no downside from what I can tell.
Stabilisers: never noticed much of an extreme difference with stabiliser settings in this game, 3 / 5 is a go-to for me at this point.
Brake balance: The Cappuccino doesn't have much of an issue with braking stability, especially with the ride height settings, so this doesn't matter much, I just went with 24 / 22 and it seemed to work fine.
Gears: here we go. I couldn't really show this in the video without going through the whole process, but I did something called the 'gear trick' to give the car extremely close gears. The Cappuccino has a narrow power band at high-RPM's, which is why I drove in manual and geared up as late as possible for the best acceleration. Using Auto Setup 1 with a very fast final gear, then slowing down the final gear, gives you the best gear ratios for close gears. The gears in the video were set up with a less efficient method than the one I use now. To replicate them, set the final gear to 5.500, then set Auto Setup to 1, then set the final gear to 3.400, then set 1st through 5th to 2.531, 2.020, 1.590, 1.265, 0.985. The tricky bit is finding the right final gear that gives the car enough top speed without sacrificing the 1st gear launch, as the Cappuccino is only a 5-speed. I was almost hitting top speed on the long straights.
Downforce: max front and rear, pretty much no reason not to, unless the car has extreme understeer which lowering the rear downforce can help with.
LSD: I set Decel to 15 because I was having issues with the Cappuccino divebombing uncontrollably into corners with PAL 25 FPS physics. On a higher frame rate, I'd set this lower to let the car turn into corners more easily. I don't want the LSD to activate and cause understeer while accelerating, so the Initial and Accel are set to 1.
Hopefully that explains what was going on, and why the Cappuccino was punching above its weight. It's a surprisingly fast car, one of the best sub-197hp cars IMO.
