I've increased compression and ignition timing a little bit since there was room to do so pretty much for free, not much of a change though. I also changed gearing which improved acceleration pretty significantly. I made front brakes bit more aggressive since comfort hit wasn't big and it helped a lot with stopping the car and tameness score, setting them so much towards comfort is something you can do in later years when brakes are a bit better. Tires are now sports compound since it's nice upgrade that won't cost much and off-road score wouldn't be very good anyway. I completely changed suspension, I find picking preset corresponding with what you are going for and then tweaking from there in small steps yields best results, there is always something to gain here, presets aren't perfect. BTW downforce slider doesn't do anything unless you have downforce under-tray, in similar fashion aero inclination won't do anything unless you have lip or wing on the car.
My advice I guess is to tweak stuff and see how it impacts your car in statistics, at some point you'll know enough about how it all works to go straight for what you want to do. Well that's how I'm going about it anyway, seems to work so far

. Also pay attention not just to main statistics but also stats under them in Detail Stats screen, there is useful stuff there like for instance wheel spin penalty, if it's high your tires can't cope with power you're sending to them, you may try to get bigger wheels, change gearing or if all else fails maybe reduce power. Actually compare your version with the one (below) I tweaked. Yours get -10.2% penalty on this, mine gets -5,7% and that is with change of tires back to medium compound. What's up with that? It's pretty much exact same car with same engine. Difference is in much longer first gear that helps to reduce excessive wheel spin which also helps to improve 0-100 time. Devil as they say is in the details
