what kind an size spring should i run to drag race an street race? what would help me hook and hang a curve?

Pick what your favorite is and start there. Drag racing requires softer suspension, street racing is illegal so don't worry about that and road racing requires a stiff suspension. So maybe buy more cars so that you can have everything on one key ring

Well, there is no simple answer to this. You can't really excel at both too much without making a sacrifice with one or the other....ultimately, you sacrifice both.

The go-to setup on a Third Gen are the Bilsteins and Koni struts/shocks. The Koni setup will offer adjustability, so you'll be able to better dial the suspension in for what you're looking to do.

A drag setup will want an entirely different combo than something that will handle. It sounds like you're wanting to drag race a bit more in a straight line than you want to handle. If that's the case, I would recommend a drag setup with our street sway bars. QA1 offers adjustable front/rear struts and shocks for the car that are really more designed for drag. They can be adjusted to be a bit more compliant for street use and with our sway the car should feel comfortable through corners.

Let me know more about your goals and priorities.
