stock springs spring rate.

ok so i have tien s-tech springs and i wanted to compair the spring rate of these springs to that of the stock springs. also i just wanted to know if the label f on the springs means front and the r means rear.

i assume f means front and r means rear... cant help you oin the reat though

what is there to compare really? a aftermarket spring with a higher spring rate than stock is going to be stiffer, thats pretty much all there is to it.
