Hi everybody, I'm trying to do a setup for the BMW M4 gt3 but I need an information. Does anyone know the optimal temperature that tyres have to reach? More than 100°C?
I personally never looked into temperatures on any cars, what i do is do couple of laps (10 or so) see how tyre wear is. this way u know which tyre and axel is taking more stress. You can tune this with ARBs and spring rate. so for example if you have more rear wear after couple of laps means rear are working bit hard so you can soften the rear spring ,arb or maybe even softer damping can help (but not as much as first 2) OR you can stiffen the front arb and/or springs and damping. also lowering toe close to zero also help with wear.
Keep them as cold as you can manage whilst not sacrificing too much lap time. Rear axle starts to do some funny stuff once you go above 100 °C, and generally lower temps mean slower thermal degradation over a stint.
