I've gone by the mentality of balancing out show with go. With the power I have at my disposal I think a sway bar and brake pads/lines might be next. I think those two things will really allow me to control the car around bends and when I need to stop quicker; the stock brakes just don't cut it
They aren't great, but not the worst I have driven on.
I'm not sure what else you have on the car, but I'm super pleased with the setup I'm running now.
A full bolt on stage 2 car is perfect all around. Enough power on the interstate and plenty for back roads.
I was in a tight autoX session 2weeks ago, and was overwhelming th tires on multiple occasions.
Intercooler will really help too.
Rear sway and wheels/tires are my next step.
