4-Point Roll Bar - Nissan Factory Style


Fairlady at SMT for the roll bar fabrication

I had the 4-Point roll bar custom fabricated at SMT in Makati. They used schedule 40, 3mm thick iron tubing with an outer diameter of 45mm. They used 1/4 inch steel plating for the backing plates with held down by 3 bolts for each plate.



Clean welds for the seatbelt mounting brackets

Nice clean fabrication, which clears the soft top mechanism and hood. They also installed a cross beam for the 4-point seat belt mounts, which also acts as a strut to strengthen the rear end of the chassis and roll bar mounting points.

1/4 inch steel plating reinforced by another steel plating underneath, held together by 3 main bolts

Roll bar clears the soft top, good fit underneath


Roll bar is bolted to the factory roll bar mounting points on the body, which directly connects with the chassis underneath.



Still leaves a good room for luggage at the back even with the roll bar installed.

Very clean and precise fabrication work from SMT. And the owners were pleasant to talk to and share ideas with.





Paint was done by CarPath Paint Shop - a primer coat, 4 coats of black, and a clear coat after fine sanding the base coat. Then a whole lot of buffing with rubbing compound to polish the clear coat evenly. Good clean job.


Looks great after the paint job by CarPath. The black roll bar matches with the red paint of the Fairlady.

Cross beam acts as chassis stiffener and seat belt mounts. I even noticed an improvement in the ride after driving around after the roll bar was installed. And this places additional weight in the rear and plants the rear tires for better traction.


Roll bar probably weighs in at 15-20 lbs.

Definitely adds that cafe racer feel to the Fairlady. Functional and stylish at the same time.



Finally, a sweet Nissan Competition Style roll bar for the Fairlady.
