I'm curious on the tires, are you actually driving them on the street? I thought they were too soft for a dual use setup. My car is used the same way, sunday driver and as many track days as I can do but I may drive from VA to NY on a weekend once or twice a year. I was probably going to go with nitto invo's since they seem like the best compromise on traction and longevity for a dual use vehicle. I'm too poor to have 2 sets of wheels/tires and will probably be getting a 20" 10 and 11" setup sometime this winter.
My engine and suspension setup is very similar with only some different brands here and there. Brakes are stock with better pads/fluid since I run shorter courses near me that focus on handling and not a lot of high speed straights.
