Best of both worlds

My T/A is an all around car...I drive her to work on nice days (highway cruising); I go to the drag strip with my buddies; and I go on winding backroad cruises with my car club. I want to upgrade from my KYB shocks and Eibach Prokit Springs. I've had them on the car for 4 years and 10k miles. I was a collage kid when I bought them, and now that I'm graduated and making better money, I want to upgrade my suspension to the same level as my drivetrain.

If money wasn't an issue, what shock/spring setup would you get?

I was looking at the QA1 Double Adjustable Coilovers for all four corners, but I'm not sure what spring to get with them. Like I said, the car sees a little bit of everything, but if I had to pick ONE setup for the suspension, it would be for drag racing.

Here is a quote from a vendor:

Springs-
275lb - Drag Racing
300lb - Nice Ride & Handling
325lb - Firm Ride, Great Handling/Cornering

Is it a good or bad idea to mix spring rates? I was thinking 325lbs for the front and 275lbs for the rear...drag racing is supposed to have soft in the rear, correct? If it's not a good idea, I would drop the fronts to 300lbs, but I'm definitely not putting drag springs in the front.

Opinions?

On a completely separate note: If I was to run coilovers in the rear, would I still need to the run the stock style springs for ride height, or do the coilovers take care of that?

The spring rates are mixed from the factory and so are the dampers/shocks..

Front spring rates are always different than rear spring rates because of the front and rear weight differences..

As far as what rate is right for your setup,, sorry no answer, it will depend on personal preferances..

Personally I'd go with Strano or LT1 Eibach springs and Koni or SLP Bilstein shocks.
If the car is going to mainly a drag car running the stiffest available stock spring in the rear and the stock v-6 springs in the front would get you better results(from what I've heard).

Here are spring rates to consider.

If you go with the QA1s go with the 325 lb kit.
