I was researching the different seat pressures and bind extremities on the different valve springs that i plan on putting in my B16A2 w/CTR cams. Since its just cams w/gears, a mild setup (if that), I was wondering what the significance of the coil binding distance is. Also, the Omni springs have a seat pressure of 55lbs while the ITR has 65lbs or pressure, which is best for my setup? What rpm does the CTR stop making power at? TIA.
