In one of my Steve Smith books it says to increase the lf spring rate 100-150 #s if your car is loose on dry slick.

It says running reverse spring split is ok if the tracks not high banked.

"It says it will keep the lf from lifting up too far and thus keeps the wt at the left front corner. If a car pushes going into a corner reduce the rf spring rate".

I guess I dont see how a spring effects it lifting too far???????? also increasing the lf would reduce your crossweight on entry and loosen entry????

I can tell you - Steve Smith has never been in a race car.

I've got that book. Some of the things in it work backwards. If you read carefully you will find the book giving opposite set-ups for the same situation. The best thing you could do is do spring reserch. Find out how they work.
Knowing that a 1200 spring is stiffer is only 1/2 what happens. Remember the car rolls on the springs. A 1200 and 900 compared, the 900 will have more wheel travel and thus keep weight on that wheel longer.
A spring is a lot like a cam. Lift as rate and duration as length of time weight stays on the spring.
