Gerald,
We realize that for every degree of angle of your shock is canted, you lose a percent of spring rate. So, regardless of what the actual spring rate actually is, we just use say, 350 /250 as a basic starting point and then maybe hone in from there. Plus, there's not really a right or wrong spring rate either. You could use very light springs for a soft mushy ride, or more than double the rate for autocross. But you can't have both.The idea of canted shocks is that it gives more travel without having to use an extreemly long shock. Anytime a shock is canted it will always have more travel. A car with 6" of travel with near verticle shocks will yield a car that looks like one of those 4WD AMC cars from the 70's, I don't think that is what you're after is it? Cobras generally have around 2 or 3 inches of travel.
Good luck,
Tim
