I have been around and around with this discussion with my G-Link. I first installed a set of Speedway Motors take up springs similar to those listed earlier. This kept the main spring in place at full drop but once I installed the exhaust the full drop would allow the drive shaft to come in contact with the mufflers. At that point I had to install limit straps similar to the ones listed at the beginning of this thread to limit the shock extension to 14". I currently still have both devices installed in the car.
