I think the race_s setup is quite fine then, maybe just lower the brakeforce to ~900Nm if you use mouse. that's not meant to be a funny answer, but in my opinion it is better to keep using that setup until you drive 1:25s or faster - instead of switching to random setups every now and then, hoping to find big improvements within one lap.
I don't upload the setup I use since it is not my own one, but I recommend you to improve your racing line and braking points before testing thousands of setups
at www.lfsworld.net you can download XRT/BL1 hotlaps (S2 Hotlaps -> Hotlap charts -> XRT; click at the laptime you want to watch, save it in your lfs folder /data/spr) and watch them onboard (V to switch view) if you want to work on your racing line - good luck!
Thats the setup I used to use when I was a demo user using a mouse. Can't remember the laptimes I was getting, but I could easily win from that back. But thats just Demo-ness, not really my skill
