The JP Porsche 911 991 GT3 Replica Half Cage is an ideal choice for those looking for a reliable and lightweight half cage to fit in Porsche 911. This design replicates the styling of the GT3 cage using Bs4-T45 metals to ensure the frame remains lightweight, and fits using existing mounting points in the car. This cage can be fitted with both types of Porsche 911, Panoramic roof, and non panoramic roof, ensuring you will be able to select the cage which best suits your needs.

Key Features:

  • JP Cages use only the best materials for their cages.
  • Available in a range of colours.

Fitting Process:

  • Remove the Front seats
  • Remove the rear seats
  • Loosen or remove the carpet which sits under the rear seats
  • Remove one of the rear side trims from B pillar back to rear window
  • Remove the rear window bay trim which covers the fuses and wiring
  • Remove the nuts from the rear strut tops
  • Place the rear section of the cage so it lays on the step below where the wiring is with the mounts under the one remaining trim against the step shelf where the wiring and polystyrene is. This will allow you to refit the Side Trim you removed by sliding it between the cage and the car and popping it back in place.
  • Once the trim is back in place you can now move the rear section of the cage up and into position onto the strut tops and put the nuts back on, just leave them finger tight so you have movement to fit  the front of the cage.
  • Now you have the rear in position you can remove the 2 bolts which go through the rear seat beam
  • Sit the front part of the cage on the beam and fit the bolts through the cage feet and the beam loosely.
  • Fit the bolts into the lap joints which join the two halves of the cage, you may need a woggle bar or old screw driver to assist in aligning the holes.
  • Once all the fasteners are in place you can tighten them all up.
  • Now the cage is in place you can refit the rear window bay trim and the carpets and seat delete kit, this can be a bit fiddly to get back in place but the trims are flexible enough to pass through the cage, you may need someone fairly small or agile to lean through the cage to refit.
  • Fit the seats and Enjoy.
