I used Hami's tune:

with some modifications to fit my driving style. I cannot express how much I hate understeer. I can deal with oversteer & adapt my driving to that, but not with understeer apparently. Turning less sharply or going easier on the throttle is intuitive to me. Understeer makes me feel like I'm fighting the car. I want to turn MORE and I can't! AHHHHH. hehe You get the idea.
The idea was to eliminate as much understeer as possible in this car. It helped me to be able to deal with the car and drive it more naturally. This may not work for everyone, but if you're still struggling, it's worth a shot.
My changes are as follows:
Car fully broken in. I was struggling to begin with and the car was almost there anyway, due to the retries, so I finished the job. This is not
necessary to do, but if you're already close, you can. You can ease up on the PP changing down below if the car isn't broken in yet.
LSD: 5/5/15
To allow for sharper turning.
Power Limiter: 100%
Hami's tune lowered this to meet the PP requirement. I went about it a different way.
Ballast: 82kg @ position 50
This will get the car to the PP limit, but that's not the main point of it.
Yes, that does actually say to put it at the
back of the car. Most everyone was putting ballast at the front, with the idea that the wheels that turn and propel the car would have the most grip. This makes perfect sense and should actually be the way to go, but I've found that it feels like it puts
too much pressure on the front tires and makes it harder to turn it. Much in the way that carrying 4 cinder blocks would make it hard to walk. Sure you have great traction, but you're being dragged down.
Putting the ballast at the back, like I did, seemed to take a little of that pressure off. What it
really seems to do, in my opinion, is it helps the back end of the car swing around a little quicker. While the front wheels are turning and pulling it. Before I did this, it felt like the front wheels wanted to turn, but the back wheels wanted to go straight, like a train on a track. It felt like the car was fighting itself.
With this setup, I was able to feel like I was driving the car, rather than fighting it. No, it won't make the Clubman Stage easy. That one is going to be the one that you need to use all of your good driving skills (you have been practicing those, right?) to get smooth lap times.
I will say that, for me and my driving style, making these changes made it easier to get the most out of each turn and it wasn't so much of a battle.
Obviously change the Final Gear on the transmission for each track, so that you're not quite hitting the limit. For Autumn Ring Mini & Tsukuba it needs to go all the way full right. More acceleration, less top speed. For the others it needs to come down close to Hami's.
Because of the changes that I made to the car, I actually put it more to the right that he had set up for CSR5. It gave me more accel during the curvy parts without killing the top speed on the straight. Experiment for what works for you, if you try this.
Like I said, this may not work for everyone, but I was able to nail 4 of the 5 tracks well with this setup. The CSR5 is just a pain in the booty no matter what you use apparently.
