#1, good tires like R-S3s or Star Specs. #2 would be light, wider wheels. #3 would be quality coilovers. KWs or JRZs. To go more extreme, remove weight from the car.

Very much so. The same tire as 32 psi and 36 psi will feel much different in response. In autocross where you make short jogs, you use high pressure before higher pressure tires tend to turn in better than lower as they have less surface resistance. But too high will sacrifice a lot of grip so it's a balance. Every tire compound is different. On road course where you build up a lot of heat, run lower pressure since more heat adds more pressure. I start at 30-32 on my RS3s on track vs 35-36 on autocross.
