Buying springs depends on setup, car weight, and brand of springs. I run on a 3/8 mile track with long, banked sweeping turns. I've found that my car works best with the rear springs straight up as far as spring rate. I drive the car straight and use stagger to help turn the car through the center. Also, my car must weighs 3,400 lbs according to our rules, so I choose the springs accordingly. Afco recommends a 205 lb spring, and Landrum recommends a 225 lb spring. The main factor, however, is the track turn radius and banking. Racer17j needs to keep the back of his car tucked in off the corner, so he can get more bite. Thus, he has a stiffer left rear spring. My track is probably a bit more of a momentum track where I'm feathering the gas all through the corner on the high side where the back coming out a tad ( and i mean a TAD! ) isn't that bad a thing, it helps turn the car. All that said. I'm probably wrong. I've run only 10 races (couple of seconds though) but I read a lot, and that's what I get out of it.

What about a heavier spring on the LF than RF? I heard that makes your car not push going into the turn.
