struts and springs-school me

90 GT vert that sees 12-15 autox events/year. Both my wife and I race it so it sees double duty. Drag and Road race also but the primary is autox. Daily driver.

I'm leaning towards the Koni Sports, (single adjustable), they seem to be the best strut for the money for my application. Anyone know what is the best spring match for performance.

Can I run coil-overs on the front and springs on the back?

Thanks...

Here's how I decided on the Konis...

Koni DA's are pricey ~$1k, but very tunable, (rebound and compression) too pricey plus I don't want to have to deal with all the minute tuning details.

Bilsteins. I'm sure they are good, very good, less expensive ~$600. But when I leave my track and hit another autox track or go to the drags I need some adjustability.

KYB AGX/Tokico Illuminas. Inexpensive ~$450. Both are single adjustable. BUT, they adjust both rebound and compression at the same time. Not good for tuning at the track.

The Koni Sports (yellow) are also single adjustable BUT, only adjust rebound. ~$640. This seems like it would make for a quick easy tune w/o so we can drive...

Opinions please
