I have been modifying the LMSC torque for a more realistic value but I have noticed a slight wheelspin. Where do I change the tire grip?
You can get high grip bu setting the "Jupiter" static downforce cheat at -24.92 value in Environment options. IT WORKS WITH ALL VEHICLES AND PROPS. I'll upload the demo video on YouTube later.
It works, trust me. I tried even with not sport cars and then I performed correct manoeuvres at high speed. ALTERNATIVELY He can adjust aerotechs to gain grip and run in vehicles with wingtips. The higher the speed, the stronger is the grip.
That sin't what he asked though, he asked about how to change tire grip. You obviously don't know (and neither do I) so, politely, bugger off.
change your tires. or go into the tire's jbeam and adjust the values. there's some complicated math involved, but simply adjusting the "frictionCoef" and "slidingFrictionCoef" will increase your overall traction
If you're going for realistic values, wheelspin is fine. Even LMSCs with should be able to easily spin their tires in first or second. NASCARS can pretty much spin their wheels in all gears if you try hard enough. It's just the consequence of having a lot of power in a RWD car with no aero. If you really want more grip, you can increase frictionCoef.
