This cam was designed for ease of tuning and drivability, along with a smooth, factory type idle. As with all BTR offerings, you can be sure you're getting the utmost reliability as a result of thorough testing on our in house engine dyno and Spintron."

NSR cams are designed to be compatible with factory springs, however, you MUST ensure that the original springs are not worn and are capable of supplying adequate OEM spring pressures.
