Rear Tension Gauge
Designed to provide the chassis stiffening of a roll cage but keeps the rear seats accessible to retain the drivability and comfort for the streets. Features adjustable stiffness to tune the level of stiffness. Note this is NOT a roll cage and is not designed to meet the standards of NHRA, SCCA, FIA and other racing organizations. ( and most unlikely cams as well )
=========
This cage bolts straight into r33, using the side seatbelt mount points. This is more for adding rigidity to the chassis rather than a full on roll cage. Allows you to run your backseats and can be torqued in the centre loop to increase tension around the main loop.
This is the more expensive aluminum model, and is very light and of course the Do-Luck quality, further pics can be taken of the gussets to show the workmanship in this.
The drivers side loop has the side tab to run the seatbelt extender as well as original seatbelt mount.
Price: $450.00 bargain considering how much they are new.
Condition: Excellent condition, clear coat on aluminium is shiny like new, only on the main loop (top towards roof liner) is some blemishes where some sticky tape padding has been.
