As I posted in Roberto Costa's F1 2012 Total Overhaul thread, I have been working toward adjusting car performance — most notably top speeds as a result of the game's too-powerful DRS effect — to levels actually seen at the circuits this past season. Using the official Formula 1 website's results section and the McLaren team's website, I have arranged the document below which illustrates the top speed reached through the speed trap during free practice, for positions P1 and P10 (P24 was typically too slow to compile a reasonable average). This, along with the McLaren team's data on straightaway length and full-throttle duration, aided me in finding that just three "baseline" setups are needed to suit all 20 circuits on the calendar. 1. Extreme low downforce, low drag. Monza only. 2. Extreme high downforce, high drag. Monaco and Singapore*. 3. Medium downforce and drag. Applies everywhere else. * Singpore is not merely a simple "copy-paste" of the Monaco data, as Monaco has very specific car data for steering lock, suspension durability, brake pressure, transmission shift times, and more. Singapore uses the majority of the data from the "medium" setup above, with aero data from Monaco. I am open to feedback, but please understand I am not looking to regress back to single-circuit setups. I am content with being "in the ballpark" here. My priorities were (1) reduce the overpowered DRS and (2) adjust the clearly-wrong default setups at locations like Silverstone (which, for example, uses the same low-drag configuration as Monza). Final drive ratios have been adjusted to top out at the end of the longest straight, using DRS as early as is prudent, using 50% KERS capacity, on low fuel. This leaves enough slack to give the AI as much of the full rev range as I can with a single setup. Front grip has been increased to give a more balanced feel when using the default suspension values. This was done not to improve handling, but to give as much adjustability one way (i.e. towards understeer) as the other (oversteer). I found many of my setups before adjusting front grip saw something like 2F-9R suspension values just to get a balanced feel, leaving very little "wiggle room" if I needed to further dial things in. Difficult to explain. Baby's put down for the night, and I work early tomorrow. So without further adieu… My spreadsheet and resultant graph of top speeds: https://www.dropbox.com/s/amk0ap1gph3vflf/Speed_Trap.pdf The download (I recommend you use a mod manager such as JSGME): https://www.dropbox.com/s/3hzkij6u4n1kfqr/Revised_Performance_v1.1.zip Experimental version 1.2 (reduces grip by 5-10%, but introduces balance issues, work in progress): https://www.dropbox.com/s/l0sb1q704dovlf6/Revised_Performance_v1.2.zip Please provide your feedback! EDIT: v1.1 uploaded, including "balanced" folders for each car for use against AI or online. EDIT: v1.2 uploaded, reduces overall grip by 5-10% to more closely match actual 2012 lap times. EDIT: v1.1 linked again, still offering v1.2 as experimental version and work-in-progress.
