What springs should I get for my GTUs?
Need some help deciding on what type of springs to get. These are the choises:
Eibach -ProKit (Avg Low 0.8"F 0.8"R)
HKS (1.5 Inch Drop)
H&R (? drop)
Suspension Techniques (approx. .8" drop)
Racing Beat (approx. 1" drop)
What would be best for street use and once in a while weekend autocross?. Your suggestions would be very helpfull.

Your best bet is get springs for how you want to drive. I don't really know much about spring "kits" I have the Ground Control Coilover kit, which comes with Eibach Springs. I chose 6" 375lbs 2.5"ID springs for the front and 6" 325lbs 2.5"ID springs for the rear. This lowered my car 2" with the spring perches all the way down. I can raise my car back up to stock by raising the spring perches. Great for trips to and from the track or auto-x. Keep in mind these springs only work because I have coilovers, that setup won't work for your car, its just an example. My setup is great for a well-balanced car, very neutral steering characteristics. Although you will need to upgrade shocks with springs as stiff as mine. The GC Coilover kit is only $399, and that includes the springs. Its a great deal.

because the coilover kit replaces your spring perches...I'm not sure what the diameter of the stock spring perches are, and I don't know the heights of the springs in inches you will need to get the proper lowering. Plus the front spring perches differ from top to bottom, the front springs stock are the pig-tailed looking ones, and on my setup the diameter of the perches is the same from top to bottom.

The factory upper spring perch is a different size. The GC setup is a great addition especially if used with proper struts and the camber plate. The adjustability of that setup is all you will ever need. Downside is that it cost more. The racing beat springs are what I would use other wise. They are linear rate springs and just a little stiffer in the front about the same out back and a good compromise from the all out GC racing setup and just an improvement over the factory pieces.

I've got the Eibachs on mine. The variable rate is good on the road and a decent compromise for autocross. If you're planning to autocross note that if you use coilovers it moves you to a "prepared" class where the competition will be overwhelming. Springs that use the stock mounting will put you in "street prepared" where you can at least be semi-competitive.
