The CG-Lock simply clips onto a seatbelt (no holes or drilling). Once installed, pulling on the shoulder belt tightens the lap belt. FMVSS 208 tested and SCCA legal for Solo II including convertibles without roll bars.
The CG-Lock attaches to the tongue of your daily driver's existing 3-point, factory installed seat belt. Once installed, pulling up on the shoulder belt tightens the lap belt portion "racing harness tight" - keeping it as tight as you want until you release it. The shoulder harness remains unrestrained as normal for maximum arm and upper body movement.
"As long as the CG-Lock is installed according to the manufactuer's supplied instructions, the CG-Lock has no effect on the original factory upper body restraint and will be compliant with 3.3.1 of the SCCA National Solo Rules. This includes convertibles without roll bars.">;BR>
