Hi, Just a few quickies: * What's the unit used for tire pressure in FM4? Is it Psi? I.e. if I'm setting front and rear to 2.4, is that 24 lbs and/or psi? Please enlighten me. I'm from SEA and here we typically keep our values at either 28 lbs front and rear or 30 on all fours, depending on roads. They're not the best. * Reducing caster allows faster wheel to wheel lock, allows the front wheels to turn more/faster, correct? * How can you get some of the R2 and R3 race cars to hit higher top speeds? I've tried reducing aero, increasing tire pressure, lowering ride height, stiffening up dampers and playing around with the gear rations in a way that the final drive value is tuned for speed, and the 5th and 6th gears are made shorter for better acceleration. More top-end power.. faster redlining in top gears and hence better top speed. Thoughts? Thanks for reading.
