This happened during the S397 24h of le mans, but didn't bother to post until now, maybe it has correlation with this bug: https://forum.studio-397.com/index.php?threads/porsche-911-rsr-loss-of-downforce.64510/ So, when fitting in new wet tires, the rear tires were than they should be, the usual 29 degrees when you don't have tire warmers. When I got in the car: 29 F 29 R slicks First switch to wets: 29/24 Second switch to wets: Server crashed three laps later. Teammates had some stints New slicks fitted in 29 F29R Just posting numbers from now on New slicks 29/29 new wets 29/24 Teammates had some stints New wets 29/21 New slicks 29/29 Teammates Had some stints New slicks 29/29 New slicks 29/29 New slicks 29/29
