Now even if you are under power coming out of a corner after getting them to hot you can have the back end come out aswell cause they've got too hot under lift off and hav'nt had time to cool before you power out. With the diff open (and also taking into account that the more laps you do, the faster you go as you gradually push harder), it allows for the car to really rotate and lean on that back end hard, especially under lift off, after a while of this the rears get hot, and if you keep pushing harder they get too hot (went up to 100 after one corner) and the back end starts to hang out. Results, yes it is very much to do with both diff and tire temps! (and also how you have to adjust your driving style for each). Just did some testing running about 6 or 7 laps with diff at default 15, then at a much higher lock of 50! I also had a thought that because the rears might be spinning a bit on the inside due to too much open diff that after a few laps the rear tires maybe get a bit too hot whilst the fronts remain at optimal temp so grip slightly better, as i thought i noticed that with he diff more locked up the rears teneded to keep a more consistent temp (if not overdriven of course), but that could just be me imagining things. These are all just guess'es really so please dont take my word on any of this (apart from locking up the diff more, that definately does work). Now you can adjust the pre-load, but ive no idea what the power and coast ratios are set to as they are non adjustable and don't state what they are at (unlike say AMS2 where these values are shown, but also adjustable on the same car), but i assume it runs less lock under coast in the RF2 version.Īlso i wonder if there is any viscous locking in the Audi (IRL & in RF2) as i thought the loosening of the diff could be down to viscous fluid getting up to temp. I am refering to the official S397 Audi so I hope thats what everyone else is talking about (seemed to be but was'nt quite sure).Īnyway as for the effect occuring after several laps I can only assume (from my limited knowledge) that maybe the diff gets slightly looser as things warm up (i say this because i was finding the problem was most apparent when lifting off the throttle). Hey man thankyou very much! Im so glad its helped, a pleasure mate!
